I’m implementing an adapter board to connect an LCD to a RaspberryPi via the DSI connection on the RPi. I have a question that I hope you guys can helo me with, as I have no experience with implementing video adapters.
The Screen comes with 20 pin, 0.5mm pitch connector. The RPi uses a 15 pin, 1mm pitch connector, hence I need an adapter and have not found any off-the-shelf.
It says the driver ic is ST7701S. But I am confused at to whether the driver ic is implemented into the screen assembly or whether I have to put it on the adapter board.
I can see that the board that the Raspberry Pi foundation made for their screen has many more components than my current design, which makes me wonder if I’m on the right path.
The board I’ve made is a simple pass-through with some voltage regulators to convert the 3.3V from the RPi to 1.8V or 2.8V required by the display.
But I wonder if it should also have the driver ic, ST7701S.
I’ve seen elevated traffic from a specific country and this was hard on the heels of another post. Most of it is printer related and the DPI reference made me think they were related. (I had to delete the same user twice in the same day recently.) Plus this is a public community. When someone signs up and immediately wants to go private with a conversation I think they are trying to avoid detection. I may have been wrong but I don’t think so. I sincerly apologize if I was wrong, but again, this is a public community. Don’t sign up and start posting skype links and offering private help.
