Setting up the environment
New discovery, if cmake is already included in the environment, you can cancel it first and use the official version
Or run the command to export the environment esp-idf\tools\idf_tools.py export --prefer-systemls
If there is any error in the process, you can check the output content. Espressif has done a good job in this regard, and will output relevant information at every step
First download the latest git project, this is very important
- Installation tool
./install.ps1- Then export the environment
export.ps1
- First run in the new project folder to set the project compilation target, each project only needs to be executed once
idf.py set-target esp32s2- Then compile
idf.py build- Download and monitor
idf.py -p COM15 flash monitor
- Step by step is too troublesome, here can be directly in place, compile, download and monitor
idf.py -p COM15 build flash monitor
