boot script

The system will create the boot.py file and main.py in the /flash or /sd (priority) directory, and automatically execute boot.py first, and then execute main.py (if If the SD card is detected, execute the SD card), edit the contents of these two scripts to achieve self-startup. If you write an infinite loop (While True) program in boot.py, it will cause main.pyCan't run (call boot.py first and then main.py), and re-send boot.py without infinite loop to solve it.

• boot.py is mainly used to configure the hardware and only needs to be configured once.
• main.py can be used for the main running program.

The corresponding specific implementation code here, if you have any questions, just look at the source .

note:
* The Micro SD card should be formatted as FAT (FAT32) file system
* FAT formatted memory card will be mounted to /sd, and SPIFFS in internal Flash will be mounted to /flash
