An arithmetic shift left (SAL) and logical shift left (SHL) are the same thing, as you are not extending the sign bit. Both mnemonics are present in the spec and assembler for completeness only.

Hi,
i'm processing BC_Testrom.c16 rom. Into the rom there is follow opcode:

001200AC

In doc there is written that 00 = NOPE. What is mean 001200AC opcode? It should be 00000000?
Best regards.

paul_nicholls · May 30th, 2012, 21:43

Since there is no opcode "001200AC" I'm guessing that might be some data you are looking at in the ROM, not an opcode...

Hi,
in C# i need declare Registry array as ushort (unsigned 16bit) or short?

tykel · June 1st, 2012, 09:50

The registers are signed, so short should do.

Remember the addresses are unsigned though, so you will have to convert sometimes.

Hi,
i've written in C# this function for 0x21 opcode:

private static void loadSP(byte[] opcode)
{
//21 00 LL HH LDI SP, HHLL Point SP to the specified address. Does not move existing values in memory to new location.
int pos = 0;
String strOpcode = BitConverter.ToString(opcode).Replace("-", string.Empty);
String HHLL = strOpcode.Substring(6) + "" + strOpcode.Substring(4, 2);
pos = FromHex(HHLL);
SP = memory[pos];
}

SP is an ushort variable (16 bit), memory is a byte array (8 bit).
In SP variable i need point memory[pos] or also memory[pos+1] so i can let to SP a 16 bit value?

Prads · June 1st, 2012, 12:55

Your code doesn't make much sense. All you have to do for that opcode is to load immediate value to SP, i.e. SP = HHLL.
Also, learn to use bitwise operators please, all those string manipulation looks ugly and takes more processing.

Hi all,
Now i am working on prototype of CHIP16 debugger, because without it i can't write complex alghoritms or programs for CHIP16.

Very good, I look forward to being able to use this.

Looking very nice

For those interested in writing chip16 assembly, and who use Notepad++, here is a custom syntax highlight file.
Unzip it into %APPDATA%\Notepad++. It handles *.s and *.casm files.
Enjoy

Nice! i use Notepad++ quite a lot so i guess it may be very useful thanks!

Cool, switching user-defined languages makes my np++ crash though!

Also, I'll quickly say that a bug affecting hex DB's has been corrected in tchip16.

EDIT: Made a quick little demo, a little bouncing ball with gravity and sound. Press START to restart.

What kind of bug? It's described in Issues at google.code?

Small and nice. Maybe this should be the sprite of realy volleyball ball?

Yes, issue 10. Basically all hex digits > 9 were being converted wrong.

@tronix286: Very neat looking debugger, I like it.
@tykel: As always, good work. You should put it in the program pack

tykel · June 6th, 2012, 11:58

@Shendo: Thanks, I have another little one in the works, nearly finished

EDIT: Here it is, a demo called Water.
It depicts a view on the sea, with a boat moving in the distance. You hear the waves crashing in, and on occasion, the boat sounding its horn.
I did my best for the glitter on the sea.
Feel free to make it better!

Enjoy

So, I had some free time today (which I thought I would spend reading XBox documentation but blueshogun hasn't sent me documentation yet for some reason :P) and I decided to play around with the chip16 compiler code a little. I added an inbuilt function that lets you to write text on chip16 screen.

Hello World demo:

Code:

ConstString hello = "Hello World!!!";

void main() {
	print(hello, 10, 10);
}

Compiler still doesn't do much but I will try and update it in my free time.

Some progress with my chip-16 debugger. It alpha, but it work's!

KNOWN LIMITATION ver0.1 alpha:

- All sound opcodes ignored (interpreted as NOP)
- All FLIP opcodes ignored (interpreted as NOP)
- All PAL opcodes ignored (interpreted as NOP)

- Only one debugging mode: step by step (Trace)
- One-pass dissasembler when ROM loaded into memory. No 'on the fly'
dissasembler after each opcode execution.
- No breakpoints
- No code/memory/registers editor
- Not working stack view panel. Maybe i should refactoring this

Now at: http://code.google.com/p/chip16debugger/
