These are great, versatile boards at a fantastic price. I currently use them in place of the Arduino Nano. I am using one to control my lab power supply and 16 of them to control the lighting of our heritage railway signal system.
Thank you Electro Dragon.

its now working with P2.0 128×64 1/32.
Just soldered the jumper like the picture attached.

Wiki is definitely missing some information, but it works as intended.

Hi people,
Did someone made this module work with P2.0 128x64 1/32?
Using the DMA library and connecting the cables manually to the display I can draw all pixels.

But, while using the module I have 2 black lines, the PIN_E pin is connected to IO18 (and soldered).

My pins configuration, using DEVKITC (switch is also set to devkitc):
#define R1 25
#define G1 26
#define BL1 27
#define R2 14
#define G2 12
#define BL2 13
#define CH_A 23
#define CH_B 19
#define CH_C 5
#define CH_D 17
#define CH_E 18 // assign to any available pin if using panels with 1/32 scan
#define CLK 16
#define LAT 4 //The strobe signals is sometimes also called latch
#define OE 15

Am I missing something?
