Need help with connecting the pi 3b+ with an unamed 2.8 inch touch lcd tft

Fri Feb 15, 2019 2:42 am

I have a raspberry pi3b+, recently i purchased this screen, this is the exact link: https://robu.in/product/2-8-inch-spi-to ... ce-240320/
I wanted to make a small monitor for my pi. I searched a lot around the internet to know which pins connect to pins on the pi, but there is no clear information. Notro's fbtft documentation is not making any sense to me as i am new to all this. As of now I did some connections and lcd is showing only white color. Can anyone pls help me asap as if the screen is faulty, i will be return it soon. I need help with how to connect the pins on lcd to the pins on the pi and also how to setup the drivers and make it as a monitor.

There is a good chance this will work, the 9341 driver chip is on the fbtft list .

Touch screen chip is another SPI port?
