how to use interrupt with SKPS PS2 controller?

[gorgom]

I need to use interrupt when the PS2 controller button is pushed. Can anybody show me the example hi-tech C code?

Here the code using Hi-Tech for the SKPS PS2.

thanks shahrul.

static void interrupt isr(void)
{
if(RCIF==1) status[DATA]=RCREG;
}

From the interrupt function above, can you explain status[DATA]=RCREG; instruction more detail because the declared variable is unsigned char DATA,status[31];. Sorry, I'm quite new with PIC.

Store the status of SKPS protocol. Refer SKPS datasheet, I gather information data 0-28

CODE: SELECT_ALL_CODE

   if(DATA<28) DATA++;
   else DATA=0;
   uart_transmit(DATA);

Thanks. I get it now. There is int read_a2d(unsigned char channel); function in the provided source code. But it seem not use in the main program. Can I just delete the function.

Yes, you just delete that on re-compile either error or not.
