//Adafruit_ST7789 tft = Adafruit_ST7789(TFT_CS, TFT_DC, TFT_RST); // OPTION 2 lets you interface the display using ANY TWO or THREE PINS, // tradeoff being that performance is not as fast as hardware SPI above. //#define TFT_MOSI 11 // Data out //#define TFT_SCLK 13 // Clo...
常用的SPI引脚为: MOSI = GPIO13 (D7) MISO = GPIO12 (D6) SCLK = GPIO14 (D5) 有一个扩展模式,将普通引脚交换为SPI0硬件引脚。通过在调用SPI.begin()之前调用SPI.pins(6, 7, 8, 0) 来启用此功能。引脚将变为: MOSI = SD1 MISO ...
