This is only really useful for applications that use DrawRGBBitmap8. The
RGB444 format has fewer colors, but can be up to 25% faster than the
default RGB565.
I have tested this change on the Gopher Badge and the PineTime. Both can
be substantially faster once the code is modified to output RGB444
instead of RGB565.
* Unify the Rotation type, so that SetRotation can be used in
interfaces.
* Add Rotation() method to these displays, so that the current
rotation can be read.
* Change SetRotation() so that it can return an error (if the given
rotation isn't supported).
- FrameRate option sets device framerates from 39-111Hz
- VSyncLines option adjusts device vsync pause using st7789 "porch control" feature
- Added Rx(cmd, bytes[]) to support retrieving scanline timing data over SPI
- Added Sync functions to support syncronization of animation to vertical scanline timing
- Minor adjustments to Configure to clear screen memory before display is visible
* Fix setWindow bug, add CS pin for Clue compatibility.
- corrected bit shift in setWindow that broke high addresses
- added csPin to constructor (will now work with adafruit clue)
- small adjustments and comments to init routine based on working arduino driver
* Update main.go
Updated test example with CS pin.
* Reverting unnecessary (no-effect) change in setRotation.
