Today +was partly an orientation day, and I spent a while meeting people and stuff, +but eventually settled down to work. + +For my first project, I decided to work on an IRC bouncer in +[Rust](http://rust-lang.org/). I've wanted a decent IRC bouncer for a while - +I'm currently using [ZNC](http://wiki.znc.in/ZNC), which is the only really +usable one I've found, but it doesn't really handle disconnection well. I'd +like to be able to just close my laptop and go, and actually get all of the +messages I missed when I open it back up. The problem is that if you don't +explicitly disconnect the IRC client, the bouncer has no way of knowing when +you stopped receiving messages, so messages in that timeout window tend to +just get dropped, which makes it quite difficult to keep up with +conversations. + +The solution I'm going to try is to split the bouncer into two parts, a client +and a server. The server still runs as usual, but you run a bouncer client +locally, and that is what you connect to with your IRC client. The bouncer +client then talks to the bouncer server using a different protocol which +allows you to sync unread messages reliably. + +The first problem that I ran into is that there doesn't appear to be a +fully-featured IRC library for Rust yet (in particular, one that can handle +being a server as well as a client), so... the first step is obviously to +write one! I've done this before [in Lua](https://github.com/doy/luairc), so I +don't think this should be an insurmountable obstacle. We'll see how accurate +that assessment is this week, I suppose. diff --git a/content/blog/keyboard-mappings.md b/content/blog/keyboard-mappings.md new file mode 100644 index 0000000..5109b87 --- /dev/null +++ b/content/blog/keyboard-mappings.md @@ -0,0 +1,141 @@ +--- +title: keyboard mappings +date: "2013-11-02T20:54:00" +tags: [configuration, keyboard] +--- + +So I was at the [Pittsburgh Perl Workshop](http://pghpw.org/ppw2013/), and +[John Anderson](https://twitter.com/genehack) gave a +[talk](http://pghpw.org/ppw2013/talk/5084) about his personal configuration +setup. It motivated me to spend quite a bit of time going over [my own +configuration](https://github.com/doy/conf), but in particular it reminded me +that I had been wanting to adjust my keyboard for a while now. My pinkies have +been getting tired more quickly lately, and I'm fairly sure this is in large +part because of how often I have to use the Shift and Control keys. I do all +of my work on laptops, so it would be pretty inconvenient to get an external +keyboard, so I decided to actually put some effort into looking at ways to +modify my existing keyboard to be easier to type on. + +## Control + +One of the first things I did was read up ways to avoid finger stress. As it +turns out, this is especially common in the Emacs community (since so many of +their keyboard shortcuts rely on weird modifier key combinations), and there's +even a [project](http://ergoemacs.org/) dedicated to making Emacs more +ergonomic. One of the things that they do mention is that contrary to popular +wisdom, [mapping Caps Lock to Control really isn't a very good +solution](http://ergoemacs.org/emacs/swap_CapsLock_Ctrl.html). They recommend +swapping Control and Alt instead, since Control is used far more often, and +you can press the Alt key with your thumb, which is a much stronger finger. + +To do this, I added this to my `.Xmodmap`: + + clear control + clear mod1 + keycode 37 Alt_L Meta_L + keycode 64 Control_L + keycode 105 Alt_R Meta_R + keycode 108 Control_R + add control = Control_L Control_R + add mod1 = Alt_L Alt_R Meta_L Meta_R + +## Shift + +The next thing I started thinking about was how to reduce the usage of the +Shift keys. I do a lot of programming, which uses punctuation characters quite +a bit, and so I started +[wondering](https://twitter.com/doyster/status/388138795557978112) if swapping +the shifted and unshifted number row would be a good idea. As it turns out, +[Brock Wilcox](https://twitter.com/awwaiid) did this [quite a while +ago](http://thelackthereof.org/Keyboard_Number-Symbol_Swap), and he liked it a +lot. Using that as a place to start, I came up with [this +script](https://github.com/doy/conf/blob/master/bin/toggle_numkeys): + + if xmodmap -pk | grep -q '(1).*(exclam).*(1).*(exclam)'; then + xmodmap -e 'keycode 10 = exclam 1' + xmodmap -e 'keycode 11 = at 2' + xmodmap -e 'keycode 12 = numbersign 3' + xmodmap -e 'keycode 13 = dollar 4' + xmodmap -e 'keycode 14 = percent 5' + xmodmap -e 'keycode 15 = asciicircum 6' + xmodmap -e 'keycode 16 = ampersand 7' + xmodmap -e 'keycode 17 = asterisk 8' + xmodmap -e 'keycode 18 = parenleft 9' + xmodmap -e 'keycode 19 = parenright 0' + xmodmap -e 'keycode 20 = underscore minus' + xmodmap -e 'keycode 34 = braceleft bracketleft' + xmodmap -e 'keycode 35 = braceright bracketright' + xmodmap -e 'keycode 49 = asciitilde grave' + xmodmap -e 'keycode 51 = bar backslash' + else + xmodmap -e 'keycode 10 = 1 exclam' + xmodmap -e 'keycode 11 = 2 at' + xmodmap -e 'keycode 12 = 3 numbersign' + xmodmap -e 'keycode 13 = 4 dollar' + xmodmap -e 'keycode 14 = 5 percent' + xmodmap -e 'keycode 15 = 6 asciicircum' + xmodmap -e 'keycode 16 = 7 ampersand' + xmodmap -e 'keycode 17 = 8 asterisk' + xmodmap -e 'keycode 18 = 9 parenleft' + xmodmap -e 'keycode 19 = 0 parenright' + xmodmap -e 'keycode 20 = minus underscore' + xmodmap -e 'keycode 34 = bracketleft braceleft' + xmodmap -e 'keycode 35 = bracketright braceright' + xmodmap -e 'keycode 49 = grave asciitilde' + xmodmap -e 'keycode 51 = backslash bar' + fi + +I bound the script to pressing both Shift keys at once as Brock recommended +(using xbindkeys): + + "toggle_numkeys" + Shift + Shift_R + + "toggle_numkeys" + Shift + Shift_L + +and also set it to run when I logged into X. Note that this also maps a few +other things - besides just the number row, it also makes tilde, underscore, +left and right brace, and pipe into the unshifted characters for their +respective keys. Underscore was the biggest win, I think - typing +`$variable_names_with_lots_of_words_in_them` was always a pretty big strain. + +Again as Brock pointed out, I had to remap the keys in some other applications +to make them stay usable. Strangely enough, both i3 and Firefox continued to +work (I have `Mod4+1`, etc mapped to switching desktops in i3, and Firefox +uses `Alt+1`, etc for tab switching). Not really sure what's going on there. I +did have to add some remappings for the hint mode in +[Pentadactyl](http://5digits.org/pentadactyl/) though: + + set hintkeys=")!@#$%^&*(" + +Zsh, readline, and vim also required remapping `)` to `0`, since I use the `0` +command a lot.

This was intended to just be a brief debugging detour for a +different project I was working on, but as these things tend to go, it turned +into an entire project on its own. You can see the end result at +[https://github.com/doy/nes-snake](https://github.com/doy/nes-snake), but I +wanted to go over the code to give an overview about what programming for the +NES is like. + +The NES itself has three processors - a [6502 +CPU](https://en.wikipedia.org/wiki/MOS_Technology_6502), a custom graphics +chip called the PPU (picture processing unit), and a custom sound chip called +the APU (audio processing unit, which I didn't use for this project). Game +data is stored in [ROM](https://en.wikipedia.org/wiki/Read-only_memory) banks, +typically with code and sprite data separate - code is stored in PRG-ROM +(which consists of some number of 16KB banks) and sprite data is stored in +CHR-ROM (which consists of some number of 8KB banks). The only difference +between these two (other than the size) is that PRG-ROM is mapped to the +address space of the CPU and CHR-ROM is mapped to the address space of the PPU +(the different chips also have different address spaces). My game is simple +enough to only require a single PRG-ROM bank and a single CHR-ROM bank. + +The CPU in the NES has a single flat 16-bit address space, which contains +everything from system RAM (there is only 2KB of this), to [memory-mapped IO +ports](https://en.wikipedia.org/wiki/Memory-mapped_I/O) (so reading or writing +at specific memory locations doesn't actually access any memory, it instead +accesses some hardware pins), to battery-backed RAM on the cartridge itself +(if availble), to the actual program ROM. The PPU has its own entirely +separate 14-bit address space, which mostly holds raw sprite data, color +palettes, and information about which sprites should be drawn in which +locations on the screen (that last part is typically the only thing that needs +to be touched in a simple game). + +So this is what the basic skeleton of a small NES program (which uses a +single 16KB PRG-ROM bank and a single 8KB CHR-ROM bank) looks like: + +```asm +; .ROMBANKMAP describes the layout of the ROM banks that this assembly file +; will produce. They will end up laid out sequentially in the output file. In +; this case, we're writing a game that requires one 16KB PRG-ROM bank and one +; 8KB CHR-ROM bank, so we specify that there are two banks in total, and we +; then specify the sizes for each of those two banks. The output file, once +; linked, will be a 24KB file, where the first 16KB is the PRG-ROM data and +; the last 8KB is the CHR-ROM data. +.ROMBANKMAP +BANKSTOTAL 2 +BANKSIZE $4000 ; PRG-ROM is 16KB +BANKS 1 +BANKSIZE $2000 ; CHR-ROM is 8KB +BANKS 1 +.ENDRO + +; .MEMORYMAP describes how the ROM banks will be loaded into memory.

On the NES, the internal system RAM is located at $0000-$0800 (2KB), +; and so we can just define labels that point into that section of memory and +; use them as variables.

The NES was designed +to work on CRT screens, which work by drawing a horizontal line at a time from +the top of the screen to the bottom, at which point it starts again at the +top. This is done by a device called an [electron +gun](https://en.wikipedia.org/wiki/Electron_gun), which fires electrons at a +screen of pixels. The key point here is that drawing is done sequentially, one +pixel at a time, and the mechanism requires some amount of time to move from +one line to the next, and to move from the bottom of the screen back to the +top. The period of time when the electron gun is moving from the end of one +line to the beginning of the next is called the "HBlank" time, and the period +of time when the electron gun is moving from the bottom of the screen back to +the top is called the "VBlank" time. Except during HBlank and VBlank, the PPU +is busy controlling what actually needs to be drawn, and manipulating it at +all can cause all kinds of weird graphical glitches, so we need to make sure +we only communicate with the PPU during HBlank or VBlank. + +The way the NES handles this is to provide an interrupt (called NMI) which +fires at the beginning of every VBlank, which allows you to do all of your +drawing during a safe period of time. HBlank is harder to detect and not as +useful (since it occurs in the middle of drawing a frame), and so it is not +typically used except for some visual effects. NTSC television screens refresh +at 60 frames per second, and the CPU clock speed in the NES is approximately +1.79MHz, and so we get approximately 30,000 CPU cycles per frame, which +translates into roughly 5,000-10,000 opcodes. VBlank, though, only lasts +around 2273 cycles (roughly 400-800 opcodes), so drawing code needs to be +especially efficient. In particular, we don't want to do any game logic at all +during VBlank time, since that time is so limited. + +The other aspect that needs to be handled is system initialization. When the +CPU starts up, it's in an undefined state, so we need to set things up to +ensure that the game executes in a repeatable way. Emulators tend to be +consistent in how they initialize the system state at startup, but this isn't +true of the real hardware, so it's important to do this explicitly. Also, the +PPU requires initialization, but that is handled automatically. It does take a +bit over 30,000 CPU cycles though (a little over one frame), so we wait for +two frames before starting our main game code. Two frames is plenty of time to +do any initialization we might need to do. + +To illustrate these concepts, here is an example program which modifies the +background color every second. The details about how the background color is +set isn't particularly important (it's not really a feature you're likely to +use very often), but this should illustrate the basic structure of an NES +game. This isn't intended to be a lesson on 6502 assembly (there are plenty of +much better tutorials and references out there for that - see below), but just +to show how games for the NES specifically are structured. + +```asm +.ROMBANKMAP +BANKSTOTAL 2 +BANKSIZE $4000 +BANKS 1 +BANKSIZE $2000 +BANKS 1 +.ENDRO + +.MEMORYMAP +DEFAULTSLOT 0 +SLOTSIZE $4000 +SLOT 0 $C000 +SLOTSIZE $2000 +SLOT 1 $0000 +.ENDME + +.ENUM $00 +; declare the label 'sleeping' to refer to the byte at memory location $0000 +sleeping DB +; 'color' will then be at $0001 +color DB +; and 'frame_count' will be at $0002 +frame_count DB +.ENDE + + .bank 0 slot 0 + .org $0000 +RESET: + ; First, we disable pretty much everything while we try to get the system + ; into a consistent state.

We never reenable IRQ interrupts here because we +don't use them at all (they would be reenabled by the `CLI` instruction). Next +we disable decimal mode (this shouldn't actually do anything, since the NES +doesn't have a BCD chip, but no real reason not to do this, to avoid +confusion) and set the stack pointer to `$FF`. The stack pointer is stored in +the register named S, and it is a one-byte offset from the RAM address +`$0100`. The stack grows downward, so the stack pointer should start out +pointing to `$01FF`, and then it will be decremented by `PHA` instructions and +incremented by `PLA` instructions as necessary. Finally, we disable a bunch of +other functionality on the PPU and APU, since we don't want them to be active +until we have finished initializing. + +We need to wait for a total of two frames to ensure that the PPU is entirely +initialized, so we next wait for the first frame to end, and then clear out +the entire RAM space, and then wait for the second frame to end. At this +point, the PPU is initialized, so we can enable NMI interrupts (by setting a +bit in the PPU control register at `$2000`) and begin our main loop. + +The main loop is where all of the logic goes. In this example, we just +increment the frame count every frame, and change the background color (via +some magic) every 60 frames. This allows the NMI interrupt to do nothing more +than write a single value to the PPU, without requiring any logic at all. This +illustrates the basic principle of using the main game loop to set up values +in memory, which the code in the NMI interrupt can just read and act on +directly, without requiring any calculations. + +Here are some more useful links discussing the topics in this post: + +* [NES ASM Tutorial](http://nixw0rm.altervista.org/files/nesasm.pdf) +* [The frame and NMIs](http://wiki.nesdev.com/w/index.php/The_frame_and_NMIs) +* [6502 instruction set + overview](http://www.dwheeler.com/6502/oneelkruns/asm1step.html) +* [6502 instruction set + reference](http://e-tradition.net/bytes/6502/6502_instruction_set.html) +* [NES technical documentation](http://emu-docs.org/NES/nestech.txt) diff --git a/content/blog/writing-an-nes-game-part-3.md b/content/blog/writing-an-nes-game-part-3.md new file mode 100644 index 0000000..749b76d --- /dev/null +++ b/content/blog/writing-an-nes-game-part-3.md @@ -0,0 +1,95 @@ +--- +title: writing an nes game, part 3 +date: "2014-10-15T15:30:00" +tags: [hacker school, nes] +--- + +# input handling + +Now that we have a general idea of how a program for the NES is structured, +it'd be useful to get a bit further into the specific capabilities of the NES. +One of the pretty basic (and pretty important) ones is reading input from the +controllers. + +The basic structure of an NES controller is a [shift +register](https://en.wikipedia.org/wiki/Shift_register).

All +drawing on the NES is handled by the PPU. The PPU does sprite-based drawing, +meaning that all drawing is two dimensional, and happens in 8x8 blocks. Colors +are determined by a 16-color palette, of which a given sprite can only use +four colors (transparency being one of the colors). There is a background +layer, containing 32x30 tiles, and a set of up to 64 sprites, which can each +be either in front of or behind the background. + +The PPU has its own memory space and mostly just runs on its own, handling the +redrawing automatically every frame. In order to tell it what to do, we have +to load various bits of data into its memory. As mentioned in an earlier post, +the PPU is only capable of doing one thing at a time, so this drawing must +happen at the beginning of the NMI interrupt, when we are guaranteed to be in +VBlank. + +There are four steps involved in drawing a sprite. First, we need the sprite +itself. The pixel data for sprites is stored in the *pattern table*, and is +typically (although not always) stored in CHR-ROM. It contains 16 bytes per +sprite, where each pixel contains two bits of data, so each sprite can contain +at most four colors (including transparent). Since CHR-ROM banks are 8KB +each, this provides enough room for two sets of 256 tiles - typically one set +is used for the background and the other set is used for foreground sprites, +although this is not required. The patterns are laid out in memory as two +chunks of 8 bytes each, where the first 8 bytes correspond to the high bit for +the pixel, and the second 8 bytes correspond to the low bit for the pixel +(each byte representing a row of pixels in the sprite). To help with +generating this sprite data, I have written a script called +[pnm2chr](https://metacpan.org/pod/distribution/Games-NES-SpriteMaker/bin/pnm2chr), +which can convert images in the .PBM/.PGM/.PPM formats (which most image +editors can produce) into CHR-ROM data, so that you can edit sprites in an +image editor instead of a hex editor. + +Once we have the pattern data, we then need the *palette table*, to determine +the actual colors that will be displayed for a given sprite. The way that +colors are determined is actually quite convoluted, going through several +layers of indirection. As a basis, the NES is capable of producing 52 distinct +colors (actually 51, since one of the colors ($0D) is outside of the NTSC +[gamut](https://en.wikipedia.org/wiki/Gamut), and can damage older TVs if +used). From those 52 colors, only 16 can be used at a time (although the 16 +colors can be distinct for the background layer and the sprite layer), and +this set of 16 colors is known as the palette. + +To determine which palette color to use for each pixel in a given background +tile, the two bits from the pattern table are combined with two additional +bits of data from the *attribute table* to create a four bit number (the +pattern bits being the low bits and the attribute bits being the high bits). +The attribute table is a 64-byte chunk of memory which stores two bits for +each 16x16 pixel area of the screen (so each sprite shares the same two-bit +palette with three other sprites in a 2x2 block). The attribute data itself is +packed into bytes such that each byte corresponds to a 4x4 block of sprites. +This is all pretty confusing, so here is a diagram (from the [NES Technical +Documentation](http://emu-docs.org/NES/nestech.txt)) which will hopefully make +things a bit clearer: + + +------------+------------+ + | Square 0 | Square 1 | #0-F represents an 8x8 tile + | #0 #1 | #4 #5 | + | #2 #3 | #6 #7 | Square [x] represents four (4) 8x8 tiles + +------------+------------+ (i.e. a 16x16 pixel grid) + | Square 2 | Square 3 | + | #8 #9 | #C #D | + | #A #B | #E #F | + +------------+------------+ + + Attribute Byte + (Square #) + ---------------- + 33221100 + ||||||+--- Upper two (2) colour bits for Square 0 (Tiles #0,1,2,3) + ||||+----- Upper two (2) colour bits for Square 1 (Tiles #4,5,6,7) + ||+------- Upper two (2) colour bits for Square 2 (Tiles #8,9,A,B) + +--------- Upper two (2) colour bits for Square 3 (Tiles #C,D,E,F) + +For sprites, the upper two bits of the palette index is specified when +requesting the sprite to be drawn. + +The data about which background tile to draw is then stored in the *name +table*. This is a sequence of bytes which correspond to offsets into the +pattern table. For instance, to draw the first pattern in the pattern table, +you would write a $00 to the corresponding location in the name table. The +name table data is the combined with the appropriate attribute table data to +get a palette index, which is then looked up in the palette table to determine +the actual colors to use when drawing the tile. + +The data about which sprites to draw is stored in an entirely separate area of +memory (not part of any address space at all), called the SPR-RAM (sprite +RAM). It is 256 bytes long, and holds four bytes for each of the 64 sprites +that the NES is capable of drawing at any given time. The first byte holds the +vertical offset for the sprite (where the top left of the screen is (0, 0)), +the second byte holds the index into the pattern table for the sprite to draw, +the third byte holds various attributes about the sprite, and the fourth byte +holds the horizontal offset for the sprite. The sprite attributes contain +these bits of data: + +* The low two bits (bits 0 and 1) contain the high bits of the palette index, + as described above. +* Bit 5 is set if the sprite should be drawn behind the background. +* Bit 6 is set if the sprite should be flipped horizontally. +* Bit 7 is set if the sprite should be flipped vertically. + +If you don't need all 64 sprites, you should just move the horizontal and +vertical coordinates such that the sprite is offscreen ($FE or so). + +Now that we have seen all of the different pieces of the PPU memory, here is +how it is all laid out in memory: + + $0000: Pattern Table 0 (typically in CHR-ROM) + $1000: Pattern Table 1 (typically in CHR-ROM) + $2000: Name Table 0 + $23C0: Attribute Table 0 + $2400: Name Table 1 + $27C0: Attribute Table 1 + $2800: (used for mirroring, which I won't discuss here) + $2BC0: (used for mirroring, which I won't discuss here) + $2C00: (used for mirroring, which I won't discuss here) + $2FC0: (used for mirroring, which I won't discuss here) + $3000: (used for mirroring, which I won't discuss here) + $3F00: Palette Table 0 (used for the background) + $3F10: Palette Table 1 (used for sprites) + $3F20: (used for mirroring, which I won't discuss here) + $4000: (used for mirroring, which I won't discuss here) + +So, to draw a background sprite at the top left of the screen, you would write +the sprite index to VRAM address $2000 (assuming default settings). + +The final piece of information necessary to be able to use the PPU is how to +transfer data from main memory into VRAM. This is done via certain +memory-mapped IO addresses. + +First, to copy data into SPR-RAM, you should write all of the sprite data to a +single page (a page is a 256-byte chunk of data whose addresses all start with +the same byte) in RAM, and then write the page number into address $4014 (the +$02 page ($0200-$02FF) is typically used for this purpose). The address to +start writing from can be set by writing a byte to address $2003, and so you +typically want to write $00 into $2003 before starting a full page transfer +with $4014. If you want to write to only certain parts of SPR-RAM, you can do +this via address $2004 - set the base address to write to via $2003 as above, +and then write a sequence of bytes to $2004 to store them into SPR-RAM. + +To copy data into the main VRAM address space, you use the addresses $2006 and +$2007 in the same way that $2003 and $2004 were used for SPR-RAM, except that +you need to write two bytes into $2006 before you start writing to $2007, +since the address space is larger. Since the order of the bytes matters here, +you can read from $2002 to ensure that the next byte written to $2006 will be +the high byte of the address. Note that $2006 is also used for scrolling +(which is based on the last address written to), and so you generally want to +write $2000 back into $2006 at the end of drawing. + +Finally, you need to initialize the PPU in a few ways in order to allow +drawing, which is done via $2000 and $2001. These addresses hold quite a few +different configuration bits, but the most important ones are: + +* Bit 7 of $2000 should be set to enable NMI interrupts (we did this last + time). +* Bit 4 of $2000 should be set to use pattern table 1 instead of 0 for + the background. +* Bit 3 of $2000 should be set to use pattern table 1 instead of 0 for + sprites. +* Bit 0 of $2000 should be set to use name table 1 instead of 0 (this is + actually more complicated due to mirroring, but we won't get into that). +* Bit 4 of $2001 should be set to enable the sprite layer. +* Bit 3 of $2001 should be set to enable the background layer. + +The default pattern and name tables will be fine for now, and so +initialization should set $2000 to $%10000000 and $2001 to $%00011000. + +[Here](/blog/sprites.s) is a sample program which draws a background +and a sprite, and allows you to move the sprite around the background with the +controller D-pad.
