Let's clarify a few details to get started. I have 2 questions, and I'll ask them one at a time.
Question 1:
What specific status do you want the USB-C dongle to indicate? For example, are you looking to show power status, system activity, temperature, or any custom information?
The front of the device has two USB-C ports, and I was thinking of connecting either small LED that could change color to it with some ability for me to have a program that can send a signal to it to change the color of LED to indicate the status of the comput
Question 2:
Do you plan to use a microcontroller (for example, one that supports USB communication like an ATSAMD21 or an Arduino) to control the LED color, or are you looking for a simpler LED driver solution?
