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
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

working versin with a few problems - mostly that the touch identification routine is still not 10% accurATE at telling when an actual touch has occurred.. random noise on the adcs tends to make the occasional spot apear.; fix for thi would be to detec
