which library can be use for TFT_320QVT

Hi,
This is first time i will be doing project on arduino.(I was using PIC controller’s before).
I have board which is up and running.
I was searching for libraries for TFT_320QVT tft display. i searched over the forum, but i got confused.
SSD1289 IC driver is for tft control.
This lcd has 40 pins.

Please post a link to or a picture from the display module.

Also, before doing anything, you have to figure out for sure the driver chip.
If it is a parallel module, this test sketch should be used: https://github.com/prenticedavid/MCUFRI … eadreg.ino

Well, it looks like this is a 16 bit parallel module.
You need 20 GPIOs to drive this board (16 bit data bus + control pins).

yes, its true. And may be more pins(+4) if i decided to use SD Card for images.

btw, which library will support for this tft with maple mini.

All libraries I know support either 8 bit only or SPI.
So 16 bit data bus is not used yet, as far as I know.

Btw, where did you get this module from? Display size and resolution?

Take the ILI9341 lib from the repo and adapt it to 16 bit, it should go easily.

Thanks.
I will give that try.

The first step is to READ what is printed on your pcb.
TFT_320QVT_ILI9341 means ILI9341. The older boards use a SSD1289.

UTFT supports SSD1289_16 and ILI9341_16
Many other libraries support both of these popular controllers.

There is nothing much different between 8-bit and 16-bit interface.
All of your high level graphics is the same.

TFT_320QVT is only written on tft pcb board.
So, i think controller is ssd1289. So, it’s not worth to try to ILI9341 driver code.

UTFT library is configured for 8080 or for 6800?
