Is there a way to record several seconds (2-3 seconds) of data at 1khz or even 10khz? I'd like to store 6 words per iteration.

6 words * 2 bytes = 12 bytes
12 bytes * 1000 hz = 12000 bytes/s...

Thanks for all the help. Because of it I was able to finish the robot project I was working on using optical encoders (instead of potentiometers... PID + nonlinear, 270 degree pots ==slow || messy)....

If I go over 1 page of code (2k words, right?) is there anything I need to worry about w/my current code? I know the pbp code will take care of itself, but my ASM ISR might not. I do use PCLATH for...

Thanks! That seems to have done the trick. I'm using MicroCode Studio Plus, is there anyway to see what variables are stored in what banks?

Also, more importantly, I'm not currently...

My main code (updated):

LCD_Init_PortD.inc:

That is defined in generic_include.inc. I moved it to my main pbp file and removed that include, and it still does the same thing.

Does this have something to do with stacksize? If you overflow...

Sorry it's a bit of a mess. If I comment the "IF" on Line 343, with the corresponding ENDIF, the code runs much more consistently. Also,...

I'm using a 16f877a on a Lab X-2 board, at 20mhz. I'm using microcode studio plus w/PBP and MicroCode Loader bootloader.

My program has an assembly interrupt routine, which to my knowledge is...

My interrupt is an assembly interrupt, so I can't have PBP code there... right?

I am working on a PID controller that also does the quadrature decoding of an optical encoder (which I made tehehe). I have it basically working using assembly interrupts.

The basic operation is...
