- 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
