I use P10 SMD outdoor panel and esp32 controller, and I follow the tutorial on youtube from utech "https://youtu.be/34B4FqgmSSc?si=NphyZaQfVP_f4VvG" with pin mapping as below
and this is the link to the P10 panel that I use P10 SMD RGB 1/4 SCAN
//>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> 01_Test_P10_RGB_32x16
// This is how many color levels the display shows - the more the slower the update.
//#define PxMATRIX_COLOR_DEPTH 4
// Defines the speed of the SPI bus (reducing this may help if you experience noisy images).
// The original value of PxMATRIX_SPI_FREQUENCY in the PxMatrix library example is 20000000.
// I changed the value to 10000000 because if I use the value 20000000, then "ghosting" or "noise" appears on my P10 32x16 RGB panel.
// Each panel may be a different case. If "ghosting" or "noise" appears on your P10 RGB panel, try changing the PxMATRIX_SPI_FREQUENCY value.
// You can use the values 20000000, 15000000, 10000000 and 8000000. Or you can also try using other values.
#define PxMATRIX_SPI_FREQUENCY 10000000
// Creates a second buffer for backround drawing (doubles the required RAM).
//#define PxMATRIX_double_buffer true
