GFX Forever: The Complete Guide to GFX for IoT

GFX works anywhere, on PCs and IoT gadgets, plus everything in between. It is cross platform and compiles with GCC or Clang and should be standard C++14 (17 preferred). It is device independent, allowing you to make your own drivers. It will use those drivers in such a way as to reduce the amount of I/O necessary to make the driver work, whether it's SPI or I2C. Not only that it will draw anywhere, even ASCII to the console or serial port.
