hello , I have 4 panels each is p2 64x64 , so i was also hoping to make 128x64 or more . I am not able to correctly workout how to use only one 64x64 . I started by modified ESP32-HUB75-MatrixPanel-I2S-DMA.h and added MATRIX_HEIGHT 64 and E_PIN_DEFAULT 32 but the result is not correct , i think i might have a wiring issue but also could be i did not modify the examples correctly . I will keep on trying until i get it because I only got the panels today :)

64x64 worked better with the other examples but still not perfect

ok i was able to fix the examples for 64x64 , please see if you can also modify the same to fit yours until i get the extra cables to chain an extra 64x64 .

What I did is modify ESP32-HUB75-MatrixPanel-I2S-DMA.h ( made it 64x64 ) . And then inside the examples I have copied the function below from 2_PatternPlasma.ino :

HUB75_I2S_CFG mxconfig; mxconfig.mx_height = PANEL_HEIGHT; // we have 64 pix heigh panels mxconfig.chain_length = PANELS_NUMBER; // we have 2 panels chained mxconfig.gpio.e = PIN_E; // we MUST assign pin e to some free pin on a board to drive 64 pix height panels with 1/32 scan

And added them to the other examples and they worked , here is a copy of all the modified examples that worked . Just a note that some of the examples will reboot the MCU but if you press gpio0 then the next effect will work ( I face crashes with "spiro " effect only ) . I hope that will help .

My 96 * 128 panel works very well
