now I have a real problem.
On RPi I use my application with 8 intruments on Panel (and on Frame)
I want to use PWM output provided by:
import RPi.GPIO as GPIO
then using this code:
pi_pwm=GPIO.PWM(12,1000) # Hz
pi_pwm.start(50) #duty 50%
does not make a nice/clean 1kHz tone on pin 12, but some “noise”
when I do not run wxApp the sound is clean !?
Does anybody know what is going on? Why PWM is affected by wx?
