Modified Bob Stone's code for ILI9341 QVGA TFT's without touch capability. Navigation is now done with rotary encoders - two for position, & one setting the maxiterations.
Dependencies: SPI_TFT_ILI9341 TFT_fonts mbed
Fork of
Mandelbrot

Bob Stone
Should have mentioned in the above: Encoder code is specific to the STM32F4, tested on Nucleo F401, should work on the Nucleo F411..
