braineniac Posted April 8, 2020 Share Posted April 8, 2020 I try to use the pwm from GPIO to PWM control a fan. I would need around 20kHz with a variable duty cycle. As far as I understand I need to activate the pwm overlay, but its only available for the h5. Can I change the UART or I2C overlay to achieve this or should I try to write my own overlay? Is that even doable? Link to comment Share on other sites More sharing options...
