Oxford CWM Team / Mbed 2 deprecated TFT_Mikroelectronika_IL9341_sketchpad

This is a simple program using the Mikroelectronika TFT resistive touchscreen to create a sketchpad application.

Dependencies:   SPI_TFT_ILI9341 TFT_fonts mbed

Fork of TFT_Mikroelectronika_IL9341 by Oxford CWM Team

Code to make a simple sketchpad using the touchscreen from Mikroelectronika

The Mikroelectronika touch screen is a good sized display we are using for the first time in 2016. It's got a touch panel layer and can be addressed by either SPI or parallel buses.

Pin connections for use with an mbed

Referring to the pin names on the screen pcb

Pins:

Screenmbed nameKL25Z example
sdimosiPTD2
sdomisoPTD3
rssckPTD1
RDGNDGND
IM0GNDGND
IM13.3V3V3
IM23.3V3V3
IM33.3V3V3
CSdigitalout pinPTD5
RSTdigitaloutpinPTD0
WRdigitaloutpinPTA13

You will need 2 wires to drive the backlight on leda and ledk (anode(connect to +V via a current limiting resistor) and cathode) Link +3.3V to IM1, IM2, IM3 to setup spi communication mode link
