Hi
When I try to start a process , the code downloads fine , it runs on the
board with no errors but it only excutes the first proceess once and none
of the others.
void main()
{
start_process(fwrd());
start_process(checkir());
start_process(checkbumpers());
}
fwrd is just fd(1) fd(2) check IR is one checking digital(4) an turning
the bot 80 degrees amd check bumpers checks a bumper array and moves the bot
with the same function as checkir
any suggestions?
PS
I know the code works because ive used in :
void main()
{
fwrd();
checkir();
checkbumpers();
}
I would use the above code but it taxes the processor to much for me to run
anything else ie: low level vision , maze algotrithm
thanx

| alex, each of your processes must be an indefinite loop. otherwise starting them up via start_process just runs through once. so, e.g.: void checkir() { while (1) { if (digital(4)) { /* go backward for some time */ /* turn a little */ /* go forward (...)
