Re: Circle - C++ bare metal environment (with USB)

I searched for"BCM2837 PWM"
What pins can be used on a RPI3 for PWM? Why is this so had to fine?
I would like to flash more than one LED.
thanks in advance,
Doug Howard

Have a look at sample/13-pwmoutput. This sample program drives two LEDs at GPIO 18 and 19 (BCM numbering) using hardware PWM. Circle supports these two channels on the RPi 3 for PWM output. The PWM interface has not changed since BCM2835.
