Description: The Sharp Memory display is a blend of an eInk (e-paper) display and an LCD. It has the very-low power draw of eInk and fast-refresh rates of an LCD.
Moddable used the [Kuzyatech Sharp Memory display breakout board] (https://www.tindie.com/products/kuzyatech/sharp-memory-lcd-breakout-a2/) to interface with the display FFC and boost the ESP8266 power to the 5v needed to drive the display.
Moddable Sample code: The Piu example Balls is good for testing this display. The build command below includes the -d, debug flag.
cd $MODDABLE/examples/piu/balls
mcconfig -d -m -r 0 -f rgb565le -p esp screen=ili9341 touch=xpt2046
