Significantly optimized for STM32 boards. Supports 36MHz SPI and DMA channel

Configuration

Use "#define COMPATIBILITY_MODE" - then the library doesn't use DMA

Use "#define CS_ALWAYS_LOW" for LCD boards where CS pin is internally connected to the ground, it gives better performance

Extra Features

invertDisplay()
sleepDisplay()
enableDisplay()
idleDisplay() - saves power by limiting colors to 3 bit mode (8 colors)
resetDisplay() - software reset
partialDisplay() and setPartArea() - limiting display area for power saving
setScrollArea() and setScroll() - smooth vertical scrolling
fast drawImage() from RAM
fast drawImageF() from flash (PROGMEM)
