Spinon_code

Code for Spinon. Please check https://github.com/wjxway/Spinon and Paper "A Single Motor Nano Aerial Vehicle with Novel Peer-to-Peer Communication and Sensing Mechanism" for more details.

Warning

This code base is compatible with ESP32 arduino release v2.0.6 and ESP-IDF v4.4.3 Due to direct write of memory in RMT related code, this code is not compatible with the main interface of ESP-IDF v5.0.0 (though still compatible because v5.0.0 kept the deprecated interfaces)

Note

To get as many GPIO as possible, we fixed the interal LDO's voltage at 3.3V and freed up MTDI pin (GPIO 12). (The operating voltage of ESP32-PICO-D4’s integrated external SPI flash is 3.3 V. Therefore, the strapping pin MTDI should hold bit ”0” during the module power-on reset. So it's completely fine to do this.)

To get the board to work correctly, you have to use espefuse to burn the fuse and solidify the voltage.

    espefuse.exe --port COMxxx set_flash_voltage 3.3V

And then the board will function as expected.
