1、 Create a project folder

2、 Open the arduino IDE

3、 Select Chip

3.1. Click on tools

3.2. Click on board

3.3. Click on esp32 and select esp32-c3

4、 Configure required files

4.1Save, save the file in the folder you created

4.2Place this (sprial_72x40. h file link) file in the folder of the engineering project.


5、Burn Code

6.1. Copy the code into the Arduino IDE

6.2. 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

6.3Click on Tools in the Arduino IDE, then click on Port and select the serial port Adafruit QT ESP32-C3

6.4Click on Verify

6.5.Click on upload

6.6.The test results are as follows
