Had a few moments this weekend to put together a library to connect to uSEQ. It uses a standard common-lisp implementation (tested with SBCL) and cl-libserial-port to form a serial connection to the uSEQ device (RP2040 based usb device).

I implemented a basic REPL to have a back and forth with the device. uSEQ ships with a much more full featured library called useqedit that I would recommend most people to use. I wrote this library to fold uSEQ into my native coding environment, which is Emacs and SLIME.

The cl-useq library can be found on my github along with a description and examples.
