ESP32S3 MSC+GPIO+http client
50 USD ESP32-S3 DevKitC-1 WROOM-1-N16R8
A firmware is needed for a DIY project with the following features:
- There are two operating modes for the device, switching is done using physical buttons with the internal resistor of the ESP32S3.
- MSC - in one mode, the controller must emulate a flash drive for the computer (i.e., provide part of the internal memory), in the other mode, the controller uses the "flash drive" for reading and writing information (in this mode, the computer does not see the "flash drive").
- Switching of two TS3USB221 multiplexers depending on the selected mode.
- An HTTP request is made (via Wi-Fi) when switching to one of the modes, taking text from a file on the emulated flash drive for the request, and the response is written back to the same file, overwriting all content. After completion, the previous mode is activated.
A firmware is needed that I can upload to the controller via esp-idf-v5.3.1.
It is also desirable to implement OTA updates and indicate mode changes on the built-in rgb-LED.
More details will be provided to the executor.
