What is the most painless way to program a small micro for 2 PWM

math manipulation of input to output.
I can handle the hardware, but software is a foreign language.
Would consider easy to impliment software or a low cost programming
service. Comments and suggestions appreciated.

How bad does this program need to be done ?

1) Take the cost of your time

2) Guess how much time it would take _you_ to "program a small micro"
and double it.

3) That would be your base line to start paying someone how knows what
their doing to get it done.

If you have the time and would like to learn how to do this yourself,
I would suggest googleing for *** programmers and free *** software.

PS: Don't let the CPU zelots tell you which is best, at your level any
CPU will do to learn on.

*** = AVR, PIC, 8051, 6808, ARM, etc, etc, etc ........

PPS: I like AVR :-)

That just proves you are silly. 8051's rule! :)

I can't at the moment recall a more repulsive architecture, excepting
maybe the IBM 1401.

CDP1802 has them all beat hands down.
Hey, i liked 1802s beter than 8051s or 6502s and about as well as 6802s.

Actually, the 8051 is quite repulsive, at least as far as the on-board
timer goes. I made an interface once from ASCII to RC PWM, and it wasn't
as much fun as, say, a 68HC11 would have been.

I've never used an 1802, but from the data *** it looks like it's not
very friendly.

But I've used a 6502 to make a keyboard scanner with N-key rollover - I
found its architecture very pleasant to work with, except for the 256-byte
limit on the stack, but how deep do you need to call when all you're doing
is scanning a keyboard? :-)

Sorry for contributing to the religious uP wars. ;-)
