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. Since v2: - Rebased on PCA9552 - Model intensity to be ready for PWM use (Dave) - Remove QMP events until we get a UI visualizer (Peter) - Remove microbit patch (Peter) Since v1: addressed Eric Blake review comments - Added QMP rate limit Next steps planned: - PoC visualizer... - look at using a dbus backend (elmarco) - look at LED array/matrix such 7segments. Regards, Phil.
