sorrry I am new to this....I am using a st7735 display and a nodemcu esp32
I modified the User_Setup.h file and uncommented the following lines:
#define ST7735_DRIVER
#define TFT_WIDTH 128
#define TFT_HEIGHT 160
#define ST7735_INITB
#define TFT_CS PIN_D5 // Chip select control pin
#define TFT_DC PIN_D2 // Data Command control pin
#define TFT_RST PIN_D4 // Reset pin (could connect to RST pin)
#define SPI_FREQUENCY 27000000
and connected:
CS pin on the st7735 to NODEMCU pin D5
DC on the st7735 to NODEMCU pin D2
RST on the st7735 to NODEMCU pin D4
and ran one of the examples but the display is blank !
what am I doing wrong ?
