Peter Drescher / Mbed 2 deprecated TFT_Test_ILI9341

test vor the new lcd with a ILI9341 controller

Dependencies:   SPI_TFT_ILI9341 TFT_fonts mbed

Test program for 320*240 LCD with ILI9341 controller. Use SPI and three control lines. The IM mode pins have to be set 1110 (3-0). SPI clock has to be connected to RS labeled pin and DC signal has to be connected to the WR signal.

This driver is written based on datasheet!. I cannot test it at the moment.
