Add Custom hal example for PCA9685 PWM breakout board #98

Closed samjt closed 1 year ago

samjt commented 1 year ago

This is an example for using a PWM extender board.

My c++ is pretty amateurish, so there are probably some things to change.

One issue is that the PCA board sets brightness across a higher resolution than jled (4096 levels instead of 256). I think this is the reason there is some flickering during fades, but I’m not sure how to correct it. At the moment I’m just doing map(val, 0, 255, 0,4095) in the analogWrite call.

Thanks for the contribution! However, in order to make an executable example, it still needs some polishing. Since I've a PCA9685 somewhere around, I can take care of that and take your work as a starting point. Also I would like to put the example in a separate repository, since it has additionals dependencies (the PCA9685 driver - which I don't want to add to JLed). See https://github.com/jandelgado/jled-example-switch-sequence for an example.

Sure, I thought that would be the case but I don’t think I can open a pr to start a new repo. Feel free to close

@samjt: I have added a new library with a PCA9685 HAL: https://github.com/jandelgado/jled-pca9685-hal/

See the repo for usage examples / documentation.

Amazing, and great detailed documentation, thank you.
