Fork of TFT_test_NUCLEO-F411RE by Motoo Tanaka

Had to move sensors to a remote board because of interference. Added spi burst mode to supported displays.

To do.... ugui buttons are slow. will need to add rtos to project. Finish other way points screen. Will have to rewrite portions of the touch screen class. Sense touch, delay, read values and then average, touch released, is the sequence. Add cadence input and logic to program for computer screen.
