Serial and interrupt

[test153]

So I did and now there's only one error left...

Unable to fit variable RS2_Save

[mister_e]

well, seems we hit one of the limitation of the low-end PIC. In this case, asm INT and home made serial routine would work. 12F683 would provide better range.


Let's see what Darrel would suggest...

I suppose that the only way to write the serial routine is to code it in asm.

Damn me for choosing this somewhat limited pic

12f683 is 8 pin device and has twice the flash memory available.

Thanks for the tip, but I have already bought the other one - as I said to late to change my mind. Anyway i've been doing some diggin and I'm going forward with the ASM serial routine part. There's only one little problem - the code I'm using gives me a "Symbol previously not defined" error. How do I setup variables so I can write to them inside the asm code and reuse them in picbasic?

I can answer that, I think. The name of your variable used in the asm routine needs to have an underscore preceding it in pbp, example:
_MyVar var byte

Thanks, it worked. Now there only one other problem. I get a bunch of warnings about "Found opcode in column 1" and then MPASM gives me a "too many errors" message.

Edit: Nevermind about that error, it turned out that one need a tab space before the asm commands.
