ESP8266 （5）,驱动屏幕

news 2025/9/18 5:30:46

代码
第一步设置驱动库TFT_eSPI的默认配置文件
1，设置适配的屏幕 #define ST7789_DRIVER
2，设置屏幕大小 #define TFT_WIDTH 170
#define TFT_HEIGHT 320
3，设置屏幕驱动板端口和ESP8266对应的端口

// For NodeMCU - use pin numbers in the form PIN_Dx where Dx is the NodeMCU pin designation
#define TFT_MISO  PIN_D6  // Automatically assigned with ESP8266 if not defined
#define TFT_MOSI  PIN_D7  // Automatically assigned with ESP8266 if not defined
#define TFT_SCLK  PIN_D5  // Automatically assigned with ESP8266 if not defined#define TFT_CS    PIN_D0  // Chip select control pin D8
#define TFT_DC    PIN_D3  // Data Command control pin
#define TFT_RST   PIN_D4  // Reset pin (could connect to NodeMCU RST, see next line)
//#define TFT_RST  -1     // Set TFT_RST to -1 if the display RESET is connected to NodeMCU RST or 3.3V
#define TFT_BL PIN_D1  // LED back-light (only for ST7789 with backlight control pin)
