PCA9685 PWM Signal

#1 Post by Sasch600xt » 03 Mar 2019, 17:55

Hello all :)

i do not get a signal out of the PCA9685 ?
i do not want to drive servo motors, i just try to get a pwm signal out of the PCF9685.

It shows up after "scan for i2C device".

So i try:,1,4095

and get:
"log": ": PWM 1",
"plugin": 22,
"pin": 1,
"mode": "PWM",
"state": -1

any ideas ?
Thank you for your help
