I see Jeff did something to python, but its still the same failure.
units.py is quite simple.
===========
#!/usr/bin/env python
import hal, time, linuxcnc
h = hal.component("units")
h.newpin("G21", hal.HAL_BIT, hal.HAL_OUT)
h.newpin("G20", hal.HAL_BIT, hal.HAL_OUT)
h.ready()
s = linuxcnc.stat()
try:
while 1:
time.sleep(1)
s.poll()
if s.program_units == 1:
h['G21'] = 0
h['G20'] = 1
else:
h['G21'] = 1
h['G20'] = 0
except KeyboardInterrupt:
raise SystemExit
=============
That is it in its entirety. But changing line one from python to python3
fixed it. It running normally now ANAICT.
Thank you Jeff.
Cheers, Gene Heskett
