I've tried it with a reset-function inside my
component - but what sounds like a good idea, does not
solve the problem:
Yes, I can get very short "high-tick" outside the
timing limits of the runtime.
but I also get a square instead of only a rising or
falling edge.
I found no way to tell the stepgen.c
(without making changes inside the stepgen-source):
"do not care about any timings or the pin-state. if a
motor step is needed, just toggle the level of the pin"
this is only one data-telegram via ethernet.
but a rising and falling edge together need two
complete packets - 2 data telegrams.
this is wasted time, when the receiver is able to
interpret every edge as a motorstep himself...
now I use this
if ( stepgen->timer1 != 0 ) {
if (*(stepgen->phase[STEP_PIN]) ==1){
*(stepgen->phase[STEP_PIN])=0;
}else{
*(stepgen->phase[STEP_PIN])=1;
}
instead of this
if ( stepgen->timer1 != 0 ) {
*(stepgen->phase[STEP_PIN]) = 1;
} else {
*(stepgen->phase[STEP_PIN]) = 0;
}
in stepgen.c - and I get a square-wave
do you see any other way to get this result?
without changes in stepgen.c ?
