I have an ESP32 setup that I’ve been using for awhile using the latched approach. (RGB and ADDR are multiplexed). I got a new batch of LED displays that I notice are FM6126B based. They actually worked right from the get-go, but they are much dimmer than the other displays I was using. (I’m uncertain what those displays are based on because I don’t see numbers that I recognize from any of the various websites. They have SM5166P & J?5020GP chips.) I tried adding the FM6126B init routines and they do show “init” on the screen, but I get the same dim display. BTW, the colors also seem a little off from what I suspect…
I did confirm that the same code works on the old displays, so I’ve mostly isolated it to the display. I’m just wondering if there are configuration changes I can make that will brighten the display up. I think those FM6126 chips have configuration registers, I just don’t know how to set them up with the SmartMatrix code.
