Interfacing Larger TFT LCD display that ahs RGB interface with our nRF5340 Devkit

[Jhakan]

Hello Team,
We are currently working on  a project for interfacing Larger TFT LCD display with Capacitive touch with nRF5340 Devkit board and SoC. As per the datasheet of the LCD there are pins such as VSync,HSync which require the RGB interface in our devkit. Unfortunately we haven't found a proper pin diagram for connecting these to our devkit board . Thus we would like to know if we can interface this LCD display with our Devkit board and if  not directly can we use any add on boards for RGB interfacing separately. I have attached my pin details of the 3.95 inch display we are currently using. Kindly share your insights for the same

Hi

I will need to investigate a bit and get back to you. 

I saw there was one board that I found in the zephyr board list that might look like it do something similar.So it might be possible to take a look at the pinout there to get an idea

Do you have more of a datasheet to share? I think the 18bit parallel bus might be an issue and you would need another IC for that part

Yes I just had a check with all the  Nordic supported drivers that has an existing driver file. All of them support smaller LCD's that only have SPI for display and I2C for touch panel. The RGB interface requiring LCD's have a other LCD driver IC. If there are any add on boards that can be supporting RGB interface separately that can be integrated with  nRF5340 it would be useful.

My best suggestion would be to look into  TFT single chip drivers like they did on the board i linked below where they used a ILI9341 as display driver. This device at least has driver support in Zephyr however you will need to check if it matches your design as this is not something i'm familiar with. I think it could be worth checking if there is any breakout drivers boards to be had just to test with. Or do a good study of what they did here https://docs.zephyrproject.org/latest/boards/ezurio/bl5340_dvk/doc/index.html
