Hi everyone,
I have a Beaglebone Blue, which I am trying to use to control two 12V DC motors.
The BBBlue is power supplied by a 2C LiPo. The GPIO0 is wired to a L298N.
The L298N is power supplied by a separate 3C LiPo.
I wrote these few lines of code to test the setup out:
import Adafruit_BBIO.GPIO as GPIO
GPIO.setup(“GPIO3_20”, GPIO.OUT)
GPIO.output(“GPIO3_20”, GPIO.LOW)
but I cannot see any change on the voltage measured on the outs of the L298N.
I tried to use config-pin to enable GPIO.
Information on Internet are quite messy and confusing, IMHO.
Have I missed any step during the configuration?
How can I check whether the GPIO output is actually working?
Where can I find the correct pin names mapping/list?
Thanks in advance for the help!
Cheers,
GC.
