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.................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
