After waking up after deep sleep, I'd like to update part of the screen. But I found that after wakeup that if I don't do M5.EPD.Clear(true) no other canvas commands work. Am I missing something? Does anyone have an example of how to to do a push_canvas() on a part of the screen after wakeup, without the need to redraw the entire screen?
