Re: PICs as replacements for L297s

Many moons ago (15 years) I used to run very short courses on the use
of the Intel 8085 system development kit. (TALK ABOUT THE BLIND
LEADING THE BLIND.) I used to have 10 trainees writing code for a
simple project - like a traffic signal sequence - and have them enter
it on the kit to see if it worked. Sometimes there would be 10
different reasons why the it would not work and they each required
help.
But I ENJOYED the mental gymnasics involved.
The purpose of this post is to ask, how different is progaming a PIC
to that which I described above?

Many thanks
