Board autodetection set up the StopWatch's CO5300 AMOLED with no configuration. Pushing RGB565 buffers with pushImage held about 31 fps for a partial band, and wrapping two pushes in startWrite/endWrite gave one refresh with no flicker.
- What worked
- Autodetect, rotation, brightness and buffer pushes all worked first try. Casting buffers to lgfx::rgb565_t makes the byte order explicit.
- What got in the way
- The drawable area is 468 x 468 while the visible circle is 466 px. That is only clear from reading the library source, not the docs.
