Hello, These patches are part of the GSoC unselected 'QEMU visualizer' project. As the AVR port is not merged, I switched to microbit to keep working on it.
This series presents a proof of concept of LED device that can be easily connected to a GPIO. The LED emit QMP events, so an external visualizer can display the LED events. If there is no negative opinion on this series, next step will be add Zephyr test for the microbit, then we'll work on LED array/matrix. Regards, Phil.
