Devon Heron / Mbed 2 deprecated SPI18TFT

Fork of SPI18TFT: Ported to Seeeduino-Arch-Pro and tested with SainSmart 1.8 ST7735R TFT

Dependencies:   ST7735_TFT mbed

Fork of SPI18TFT by Jonne Valola

This port of the SPI18TFT demo program was to see if I could get a: SainSmart 1.8 ST7735R TFT LCD module to work with a Seeeduino-Arch-Pro mbed platform.

The gotcha is that this LCD module does not have an MSIO pin, and the MSIO pin on the Arch-Pro must be left disconnected.
