Working with PIC assembly can be pretty fun, but sometimes making up names for loop/condition labels and keeping track is just a pain. So I wrote this macro library that lets you write nested IF blocks, just like C or other languages.
Turns into (the nops are actually the 2nd word of GOTOs)
This is a runtime if macro library. It compiles into real run-time evaluated nested if blocks. I use it for just about everything and I hope you will too.
I tried to use nomenclature similar to mchips ie ifzf - check for z in f, not iffz - check f for z
the skipping instructions have an 'if' eqivelent ie btfss gains an 'if' but loses a 'skip' to become ifbtfs or simply ifbtf but remember that:
- btfss skips if true
- 'if' doesnt skip if true
| Code | Description |
|---|---|
| if | if stuff |
| z | zero |
| c | carry bit |
| dc | digit carry (carrry for low nibble) |
| n | not |
| f | file register |
| bt | test that a bit is set |
| eq | equal |
| ne | not equal (short form) |
| gt | greater than |
| ge | greater than or equal |
| lt | less than |
| le | less than or equal |
