For our school project we are trying to get our 2,4" TFT display to work. This instructables uses the same display. However, for the purpose of the project we need to connect it to an arduino nano and without a shield. Technically you could do this, using all the pins from the arduino. The problem is that we cannot find suitable code for this way of connecting. We don't need the touchscreen aspect of the display, only the 'display' part.
If anyone can help us that would be great!
Thank you!
You have a 40-pin 3.3V display. You must use 3.3V logic.
Do not believe the "Instructables". You need a proper 40-pin TFT Adapter shield and a Mega2560 board.
It does "look" as if your display only uses an 8-bit interface because the UTFT example uses ILI9325D_8
So you have enough pins on your Nano. But you still need to provide 12 channels of 3.3V logic. e.g. with level-shifter chips or with resistors.
Personally, I find ready-made Adapter shield with ready-made Arduino to be the most reliable.
If you enjoy soldering, you can solder a 20x2 female header to some protoboard. Solder level-shifter i.c.s or resistor voltage dividers. Either solder sockets for the Nano or solder the Nano directly to the protoboard.
Plug your display into the protoboard. And you have a mechanically robust project that is electrically correct too.
