Here is an update of my attempts to get the 16 x 32 RGB LED Matrix to display something. I still have not found a library example to work with my wiring configuration. I really thoght I could get PanelGFXDemo_16x32 to work, but no luck.
Here is how it is wired.
On breadboard. My Adafruit ESP32 Feather outputting into the 3.3v A side of 2 Adafruit logic level shifters. Then out the 5v B side to the Adafruit 16 x 32 RGB LED Matrix. I have all 4 ground wires to ground. Then 3.3v connected from the Feather to the A side of the level shifters. The 5v 2.5A power supply to the B side of the level shifters.
Here’s the pin assignments from the feather.
PIN#
R1 - 13
G1 - 12
B1 - 27
R2 - 33
G2 - 15
B2 - 32
LAT - 14
CLK - 22
OE - 23
A - 18
B - 19
C - 16
Is there anyone who can help me? I have been struggling with this for 2 days.
