Where is the pin connection list please?

I realise it's using the SPI pins 5,6,7, that's fine.

- and I see three more connections for pins 24, 25, 26, but what goes where on these?

Apologies if I've missed it in the code, or elsewhere.

Demo project to demonstrate that ILI9340 display driver and graphics library. very simple but a good starting point for any project using such a display. Please use this to thoroughly … driver, Graphics, ILI9340, LCD, SPI, TFT

You should check out my Program http://mbed.org/users/Elitism/code/ILI9340C_Serial_Control/

It lacks doxygen comments, but still the source file of the display lib: https://mbed.org/users/dextorslabs/code/ILI9340_Driver_Lib/docs/216d35e347b8/ILI9340__Driver_8h_source.html. So chip select, reset, and data/command pin.

+1 for bringing up doxygen comments !

Hi Dan,

I really should make this more user friendly! - when time permits!

The program you referenced uses the library 'ILI9340_Driver_Lib', If you take a look at the code contained in the library files there are some clues, http://mbed.org/users/dextorslabs/code/ILI9340_Driver_Lib/#216d35e347b8

To compound Erik's answer - pin 24 is the chip select signal, pin 25 is the reset signal, and pin 26 is the data/command signal.

I hope this helps! Cheers, Ian.

Thanks to you both. I feel slightly awful because I figured it out just after posting the question - despite lots of looking prior to that! I think they call it sods law...

Thanks again! (I just wish it was so easy to get stuff up and running on a beaglebone. Been struggling to get this display working on that for about a week. I am going to look at porting your code accross)

So nice to have such great support for noobs!

Cheers, Dan
