Subject: [PATCH v3 0/7] hw/misc: Add LED device
Date: Sun, 21 Jun 2020 01:07:12 +0200 [thread overview]
Message-ID: <20200620230719.32139-1-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.
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.
