I am newbie on Arduino and TFT Screens. But I am a semi-professional on programming and I decided to develop a device that can be controlled by Arduino via capacitive touch screen (there will be 2 buttons on the screen and while one of them will increase the current of a device, other will decrease). To do that, I've bought a complete solution (Arduino Mega + 5" TFT LCD + Arduino Shiled but without Resistive touch screen - this one), instead of resistive touch screen, I've bought this one and I've bought a separate PSU.
At the end, I have an Arduino Mega, 5 inch TFT Display, 5 inch Multi Touch Screen Panel with Controller GSL1680F (assembled to the Display) and Arduino Shield which is produced for this system. But I don't know how to communicate these three devices with each other. I know that, Arduino has built-in storage for the codes, and both TFT Display and Shield have micro-sd storage slots for placing codes. E.g. I don't know what is the aim of micro-sd storage slot on the shield.
As a result, is there any code samples / tutorials / video that I can follow to develop with this system? Thanks.
