Arduino development environment setup

ESP32 supports development tools such as Eclipse/Arduino IDE, and using Arduino is relatively simple. Here is the method to build an Arduino development environment:

1. Install Arduino IDE 1.8.9 or the latest version

2. Enter the espresso warehouse[2]Package and download all files

Restart the Arduino software, open the tool, select the development board, and choose ESP Dev Module as the development board to indicate successful installation

Program Download

1. Long press the IO0 key while pulling down the EN pin to enter the burning mode; Prepare a TTL serial port module (such as CH340) and plug it into the computer USB.
The connection method between the serial port module and the development board is as follows:

TTL serial port module ESP32 development board
GND GND
TX RX
RX TX
3.3V 3.3V

2. Click on the tool in the menu bar - Development Board, select ESP32 Dev Module as the development board

3. Open the program you want to download, click on "Tools" in the menu bar, select "Port" and choose the correct port number

4. After clicking "Upload", the program will automatically compile and download to the development board, as shown below:
