LM2755TMX RGB LED Driver Support #21198

Open vincentpoont2 opened 1 year ago

vincentpoont2 commented 1 year ago

The currently RGB LED Driver NCP5623B and NCP5623C that are used on many FC and GPS hardware are discontinued and will soon be unavailable.

We found a TI chip with a similar function, model LM2755TMX. We hope to use it as replacement, but it looks like PX4 does not have the LM2755TMX driver.

I am wondering if we can add support for this. The attachment is the chip Datasheet. If necessary, we can send test hardware over to anything that can help.

I've written a driver for the LM2755 in a private px4 fork. I am not in a position to upstream it.
