How to attach an LCD screen to a Pi

Sun Oct 16, 2016 11:53 am

hello every one,

I'm a newbie with raspberry pi. i'm trying to connect a TTL LCD to the raspberry pi 3 using the 40 pin connector.
i realized that i should modify config.txt file and dt-blob.bin to enable RGB output.
what i need is an easy clear procedure to do this or ready made(plug and play) files if possible.

note: im using 2016-09-23-raspbian-jessie image
thanks is advance

The first thing you need to do is to get a driver board to interface between the GPIO block and the TTL electronics of the display. The company you get the driver board from should have instructions for configuring Raspbian to use it.

thank you for your reply, actually i don't have any concerns about the hardware interfacing side since i will do it my self , i just want to know how to enable the DPI (PARALLEL DISPLAY INTERFACE) on the raspberry software side.

thanks
