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:
| Screen | mbed name | KL25Z example |
|---|---|---|
| sdi | mosi | PTD2 |
| sdo | miso | PTD3 |
| rs | sck | PTD1 |
| RD | GND | GND |
| IM0 | GND | GND |
| IM1 | 3.3V | 3V3 |
| IM2 | 3.3V | 3V3 |
| IM3 | 3.3V | 3V3 |
| CS | digitalout pin | PTD5 |
| RST | digitaloutpin | PTD0 |
| WR | digitaloutpin | PTA13 |
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
