Hello everyone, I am a happy owner of a "udoo Quad". Among other things, recently I started studying "Firmata" with "Python", using "PyFirmata" as well as "PyMata", and in both cases whenever I declare an "Arduino" pin as PWM I encounter a problem. I start the Python sketch and everything goes well. By the end of the sketch, by placing a serial closure command (e.g. board.close ()), the pin declared as PWM turns to the "HIGH" state, and no longer answers requests from PWM. The only way to get it working again is to unplug the power supply. Has anyone experienced problems in this regard? Have you solved them?
