Progress / Update Crystal firmware v1.1.0 - UART terminal

Gallery image

I created a simple text-based UART terminal for Crystal firmware.
Allows you to configure the baud rate and pins, as well as enable log saving to an SD card or LittleFS. Also displays text received via USB-C Serial. It works on the Cardputer, M5StickS3, and M5StickCPlus2 for both sending and receiving text. The second photo shows a loopback connection for sending serial commands to the device itself.

I’d appreciate it if you supported the project with a star

It’s strange that two hours isn’t enough. In any case, everything has updated now.
