Subject: [RFC PATCH 0/5] hw/misc: Add LED device
Date: Tue, 9 Jun 2020 14:34:20 +0200 [thread overview]
Message-ID: <20200609123425.6921-1-f4bug@amsat.org> (raw)
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.
