Это пятый урок из цикла «Знакомство с Arduino». 3V or 5V power supply D0: CLK Clock D1: MOSI data RST: Reset DC: data. And this can really take a while. Hi, // Declaration for an SSD1306 display connected to I2C (SDA, SCL pins) #define OLED_RESET 4 // Reset pin # (or -1 if sharing Arduino reset pin). As we are experimenting with I2C version of 128×64 pixels display we will need to run SSD1306_128x64_i2c Arduino sketch. 96" with SSD1306 controller costs about EUR 2. It seems my Bus 0 is in a stuck position with both lines high, but I don't want to reset my board in case I don't get it in this state again. The ESP32 will interact with the SSD1306 display via I2C. pdf文件28~48页。 上述指令表中有一个set memory addressing Mode指令如下:(可参考SSD1306.
