ULTIMATE performances of the SPI display driver for #pinetime : 119ms for a full screen refresh. This is not far from the maximum theoretical value of (240 lines * 240 rows * 16 bits) 115.2ms !
@JF @PINE64 is there a vsync pin or some such?
@deshipu @PINE64 I think the controller has some vsync capabilities, but I don't how they are exposed to the MCU. I'll have to have a look to the data sheet 😉
@JF @PINE64 Sadly most of those SPI TFTs don't have it broken out, only the parallel ones do. Would be great if this was an exception.
