Firmware for the arduino to communicate with the CH376 operations USB Flash Drive and SD card

I need a firmware for faculty for the arduino to communicate with the CH376S (via UART) and write a text file located on a DS card drive connected to the CH376S, when connecting the Pen Drive to the USB connector of the CH376S they are transferred to the pen drive the file: Temperature, date and time saved on the SD card separated by date.txt.

This is the first stage of a larger project, so this could lead to more work.
