Thanks Richard.

I have now placed an order and hope to take delivery some time in July.

Cheers

Very nice work Richard!
ILI9341 based TFT display with resistive touch screen could be the module that I was searching.
With STMPE610 touch controller (SPI/I2C) it would be easy to make systems that do not need any additional input devices (buttons/joystick).

Hi Richard

I am little confused how to adjust code to work.
I have a PIC18F45K22 and I plan to use it with your code but I never work with this PIC processor and I need some Help to configure it.


From datasheet of PIC18F45K22 PORTD.0 is SPI clock and PORTD.4 i SPI data out.

What I must change in your TFT_demo code to adjust PIC pin to work with TFT display.
Whether the pins of TFT displays D/C and RESET connected together on the same pin of the PIC processors or not.
