Adn development environment setup
ESP32 supports Eclipse/ Adn IDE and other development tools. it is relatively simple touseAdn __. The following is howto build anAdn development environment
-
InstallAdn ide1.89 or the latest version
-
Open the ide, click File-Preferences in the menu bar, and after entering the preferences, click Add URL
http://arduino.esp8266.com/stable/packageesp8266comindex.json in “Additional Development Board Manager URLs” -
Click Tools-Development Soard-Development Board Manager in the menu bar, and then search for “ESP8266” to install Ad n support package for ESP8266 2.5.2 or the latest version. Note: Since the download URL is from abroad, the access speed is relatively slow, and there may be download errors. Just try a few more times when the network is good.
-
Program download
-
Use a jumper cap to connect the }00 and GND pins, prepare a TTL serial port module (for example: FT232) 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
