JamesD Posted October 29, 2013 Share Posted October 29, 2013 stdio is actually a rather large library of functions. If you really want stdio, you can find some examples in the Z88DK package. A lot of the code is portable and there is MSX support so if you know assembly... have at it. A more realistic approach would be what I did on another machine One of the first things I wrote for the graphics character generator I wrote for the MC-10 were PRINTAT and PRINT functions. That was assembly but you can certainly do the same in C. You won't have the string formatting stuff but you can output text.

Have you tried compiling a 99/4a program with it, and if so can you share how to get something like a hello world up and running? Yes, it is both a cross and a native compiler. The current source is set up for cross-compiling, but once you revert it to plain K&R it will run natively. Nearly all Unix version 6 programs ran in 32KB of memory. See this paper for some background: http://www.60bits.net/msu/mycomp/terak/termubel.htm (note that it mostly speaks in 'words', i.e. 2 bytes). I'm not targeting the 99/4A. If you want to run some C on the 99/4A, Insonmia's compiler together with Tursi's library is probably your best bet. You may also want to look at Al Beard's TI-C, which he did for the Geneve 9640. That one is also both cross and native, but requires extensive bank switching for native (I believe that including all overlays it needs some 80KB). TI-C is here: ftp://whtech.com/programming/ You can use Dave Pitt's assembler and linker to complete the tool chain. Enjoy!

Fire has a value of 1, so if the routine returns 5, then you know right and fire were detected. Hope this helps. Should be easy enough to put that into the GCC compiler.

This code was taken from TurboForth and is tested. Thanks Willsy, I compared your code to Tursi's in libti99. They're very close to each other, but libti99 simply doesn't export a way to check for the fire button (in that function at least). I duplicated that function and added the check for 0x01 and it works. Code looks like this: #define JOYST_1 0x0001 #define JOYST_2 0x0002 #define JOYST_LEFT 0x0002 #define JOYST_RIGHT 0x0004 #define JOYST_UP 0x0010 #define JOYST_DOWN 0x0008 #define JOYST_FIRE 0x0001 unsigned char read_joyst(int joystick_id) { unsigned int result; unsigned char retval = 0; __asm__ ( "li r12,>0024 \n\t" "ai %1,5 \n\t" "swpb %1 \n\t" "ldcr %1,3 \n\t" "src r12,7 \n\t" "li r12,>0006 \n\t" "clr %0 \n\t" "stcr %0,8" :"=r"(result) :"r"(joystick_id) :"r12" ); if ((result & 0x0100) == 0) retval |= JOYST_FIRE; if ((result & 0x0200) == 0) retval |= JOYST_LEFT; if ((result & 0x0400) == 0) retval |= JOYST_RIGHT; if ((result & 0x0800) == 0) retval |= JOYST_DOWN; if ((result & 0x1000) == 0) retval |= JOYST_UP; return retval; } The compiler doesn't let me immediately return the result variable (which I think it should, so perhaps a bug...), but other than that I had no issues...

Tursi Posted June 12, 2014 Share Posted June 12, 2014 I based the functions on the BASIC versions, so, use kscanfast(x) for the buttons where x is 1 or 2 for joystick 1 or 2. It's three tests (two for mode and one for return value) and 6 lines of inline asm, so pretty tight. Still... I like Willsy's observation that you can read the fire button with just one more bit of CRU...

I was following the instructions in post 27. 4.6.3 probably won't accept the 4.4.0 patches. You can try, if you're willing to solve the issues if it doesn't work.

As for how to patch, you should be able to use Tursi's instructions for that without any major modifications (I think you're using Linux, if I remember correctly, so some details will be different but the overall process should be similar enough). 1 Quote Link to comment https://forums.atariage.com/topic/164295-gcc-for-the-ti/page/8/#findComment-3012020 Share on other sites More sharing options...

Yeah, I realized the question was a bit confusing after looking at it again - sorry about that. I'm sure Tursi's video will clear things up. Ironic that we have a compiler compiling a compiler (but probably not that unusual though ) Edit: Admittedly I didn't dig that far for instructions as I figured the necessary instructions, if they were included, would be on (or at least near) the first post.

Ignore the cygwin part if you are using Linux. Indeed, -p1 is a single letter command line option and hence needs the dash. Typically with Unix style applications, you need to add a "-" for all command line options that are a single letter (in this case "p") and a double dash ("--") for the long, fully written out version of those options (which in this case would be "strip"). The "1" after the "-p" is the parameter for that option and in this case means "strip 1 level from all directory prefixes". Oddly enough, if you use the long version you need to use an "=" between the option and the parameter, so the long equivalent of "-p1" would be "--strip=1", which is quite a bit more readable. Normally patch takes it's input from the terminal instead of from a file, but by adding the "<" you're basically saying that the shell, instead of asking for keyboard input, should feed the file after the "<" sign into the program. It's all very cool, and very powerful stuff and imho a lot of fun to use and get to know. You can write full fledged programs in bash scripts, and it's not that difficult to learn. 1 Quote Link to comment https://forums.atariage.com/topic/164295-gcc-for-the-ti/page/8/#findComment-3012541 Share on other sites More sharing options...
