HUZZAH32, pins and WLED

Post by drizzt321 »

So I got a HUZZAH32 ESP32, and the 128x64 OLED FeatherWing, with the intention of using with WLED-SR branch. Looking at the Huzzah pinout, I notice that IO2 is not connect to the edge, which is the default for WLED to use for LEDs. Seems like I should be able to use IO4 (A5 pin), which seems to have the same capabilities as the IO2 pin.

Just looking for a double check, should work fine?

EDIT: Also, how do I disable the flickering charging LED? I don't have/won't have a LiPo hooked up to this. Do I just need to unsolder it?

I'd think so. Can change the output pin via the web interface once the WLED firmware is up and running. Assuming that works the same in the -SR branch.

Yep. That behavior is normal and expected when there is no battery attached.

Yes, not a problem. Just wanted to double check with those who probably understand/know micros a bit better than I do, though I am learning!

Right, I understand, but is there a way to stop it? I won't ever have a battery attached, so it's pretty annoying. Well, not a battery attached to the board, I will be using an external USB 5v battery pack.
