I am currently working on a project that requires many delays in my code to
get the timing correct. I want to call a subroutine multiple times through
my main code to execute a simple delay. Right now I just use.
CALL DELAY2
Which I then have the following code to create a delay before it returns
back to my original code to keep moving along.
DELAY2:
MOV r8,20
DEC:
SUB r8, r8, 1
QBNE DEC, r8, 1
RET
This doesn't seem to delay my code all the time and doesn't always seemed
to get called. It gets called approximately 25 times in my script.
Write now I have the subroutine placed after my end statement. I have
tried it in my main code as well but seems to go out of its loop.
Is this the proper syntax to execute a subroutine on the PRU?
Thanks,
Tyler
