- Audio playback works - Touchscreen and buttons work - Bootloader works and is capable of dual boot - Plugins are working - Cabbiev2 theme has been ported - Stable for general usage Thanks to Marc Aarts for porting Cabbiev2 and plugin bitmaps. There's a few minor known issues: - Bootloader must be installed manually using 'usbboot' as there is no support in jztool yet. - Keymaps may be lacking, need further testing and feedback. - Some plugins may not be fully adapted to the screen size and could benefit from further tweaking. - LCD shows abnormal effects under some circumstances: for example, after viewing a mostly black screen an afterimage appears briefly when going back to a brightly-lit screen. Sudden power-off without proper shutdown of the backlight causes a "dissolving" effect. - CW2015 battery reporting driver is buggy, and disabled for now. Battery reporting is currently voltage-based using the AXP192. Change-Id: I635e83f02a880192c5a82cb0861ad3a61c137c3a

/* TODO: Better(?) battery reporting for Q1 using CW2015 driver
|
|
*
|
|
* The CW2015 has its own quirks so the driver has to be more complicated
|
|
* than "read stuff from I2C," unfortunately. Without fixing the quirks it
|
|
* is probably worse than the simple voltage-based method.
|
|
*
|
|
* A bigger problem is that it shares an I2C bus with the AXP192, but when
|
|
* we attempt to communicate with both chips, they start returning bogus
|
|
* data intermittently. Ususally, reads will return 0 but sometimes they
|
|
* can return other nonzero bogus data. It could be that one or the other is
|
|
* pulling the bus line down inappropriately, or maybe the hardware does not
|
|
* respect the bus free time between start/stop conditions and one of the
|
|
* devices is getting confused.
