Peace!
I'm attempting use the PWM output from a Pocketbeagle. My test code is
below:
# pwm test script
import Adafruit_BBIO.PWM as PWM
out = "P1_36"
PWM.start(out, 0,frequency=50)
while(1):
PWM.set_duty_cycle(out, 100)
However, upon running this code, I get the following error message:
Traceback (most recent call last):
File "/var/lib/cloud9/pwm_test.py", line 6, in <module>
PWM.start(out, 0,frequency=50)
RuntimeError: Problem with the cape manager
I already looked at
https://github.com/adafruit/adafruit-beaglebone-io-python/issues/262, which
did not work for me, and
https://github.com/adafruit/adafruit-beaglebone-io-python/issues/286, which
I couldn't implement because I'm having difficulties connecting the
Pocketbeagle to the internet.
Any help would be appreciated. I also ran /opt/scripts/tools/version.sh,
the output of which is below.
