1, Hardware connection:

Directly connect the Type C USB port to the computer, and the serial port will be automatically recognized after connecting to the hub

2, Software burning:

2.1. Copy the following code to the Arduino IDE

#include<Arduino.h>

#include<U8g2lib.h>

#ifdefU8X8_HAVE_HW_SPI

#include<SPI.h>

#endif

#ifdefU8X8_HAVE_HW_I2C

#include<Wire.h>

#endif

#defineSDA_PIN5

#defineSCL_PIN6

U8G2_SSD1306_72X40_ER_F_HW_I2Cu8g2(U8G2_R0,/* reset=*/U8X8_PIN_NONE);//

voidsetup(void){

Wire.begin(SDA_PIN, SCL_PIN);

u8g2.begin();

}

voidloop(void){

u8g2.clearBuffer();// clear the internal memory

u8g2.setFont(u8g2_font_ncenB08_tr);// choose a suitable font

u8g2.drawStr(0,10,"Hello World!");// write something to the internal memory

u8g2.sendBuffer();// transfer internal memory to the display

delay(1000);

}

Note: The text characters in parentheses of 'Hello World!' can only be English letters and cannot be in Chinese

2.2. Use a type-c cable to connect the computer to the ESP 32-c3 development board. After successful connection, the serial port will be displayed in the computer management window
