Subject: [PATCH v4 0/8] hw/misc: Add LED device
Date: Mon, 7 Sep 2020 18:32:49 +0200 [thread overview]
Message-ID: <20200907163257.46527-1-f4bug@amsat.org> (raw)
Hello,
These patches are part of the GSoC unselected 'QEMU visualizer'
project.
This series introduce a LED device that can be easily connected
to a GPIO output.
Since v3:
- Rebased (TYPE_TOSA_MISC_GPIO)
- Rebased (Meson)
- Addressed Richard's review comments
- Improved doc/comments
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.
