Fork of Adafruit-GP9002-Graphic-VFD-Library by Oliver Broad

Adafruit_GP9002.h@2:ecf13e85f0fa, 2016-05-08 (annotated)

Revision:
2:ecf13e85f0fa
Parent:
1:09dc95ba8711 
Caching of address and location of last byte written makes it crazy-fast for vertical-aligned drawing operations; After a pixel write any further pixel writes that land in the same display byte need only one SPI write operation to complete.
