Neopixel Support for AMLogic Boards specifically S905X #652

Open Iainrach opened 1 year ago

Iainrach commented 1 year ago

Trying to use the great Neopixel library on a Libre board but it seems like it is not supported. Any thoughts on providing this ?

It appears for the bcm283x boards you utilize the _rpi_ws281x library.

Does this mean it would be pretty difficult to get support for the Libre boards ?

Do you know of a ws2812 library that runs on the libre?

Not so far but I can drive a Max 7219 display over the SPI bus via Blinka so perhaps this could work ??

Yeah, it's a good alternative. Yeah, if there's no existing library, it can get pretty difficult to add.

Also, I think PWM support is a requirement to add to other GPIO pins and most boards don't have it implemented and if they do, it often hasn't been added to Blinka.
