I am trying to get a XIAO to TFT circuit working. I have attached the schematic. I have modified the User_Setup,h
// Only define one driver, the other ones must be commented out
//#define ILI9341_DRIVER
//#define ST7735_DRIVER // Define additional parameters below for this display
//#define ILI9163_DRIVER // Define additional parameters below for this display
//#define S6D02A1_DRIVER
//#define RPI_ILI9486_DRIVER // 20MHz maximum SPI
//#define HX8357D_DRIVER
//#define ILI9481_DRIVER
//#define ILI9486_DRIVER
//#define ILI9488_DRIVER // WARNING: Do not connect ILI9488 display SDO to MISO if other devices share the SPI bus (TFT SDO does NOT tristate when CS is high
#define ST7789_DRIVER // Full configuration option, define additional parameters below for this display
//#define ST7789_2_DRIVER // Minimal configuration option, define additional parameters below for this display
//#define R61581_DRIVER
// For ST7789, ST7735 and ILI9163 ONLY, define the pixel width and height in portrait orientation
// #define TFT_WIDTH 80
// #define TFT_WIDTH 128
#define TFT_WIDTH 240 // ST7789 240 x 240 and 240 x 320
// #define TFT_HEIGHT 160
// #define TFT_HEIGHT 128
#define TFT_HEIGHT 240 // ST7789 240 x 240
// #define TFT_HEIGHT 320 // ST7789 240 x 320
// For seeed samd21
#define HASSPI 1
#define SPICOM SPI
//#define TFT_CS 5
#define TFT_DC 4
#define TFT_RST 5 // Set TFT_RST to -1 if the display RESET is connected to RST or 3.3V
Anything I try ends up with a blank screen. Any suggestions or your own circuit and code?
Thanks,
Bill
