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.Doug Howard wrote: 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,
Honestly not. This would require to run a C++ compiler on Circle and would blow it up very much. I prefer Circle being a lightweight system, relatively easy to be understood. A console class with a command line editor may come, but only to be used inside user applications.
Would be awesome, but probably a huge task!SDL2 running on Circle would be AWESOME. Or libretro/retroarch.
Just imagine all the software automatically available as baremetal by porting those!!
