16 x 32 LED Matrix with ESP32 and level shifters

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.
