Getting started with demo programs, getting hardware docs.
Posted: Fri Apr 24, 2020 3:37 am
Hello!
A few newbie questions.
I bought a 7 inch LCD with capacitive touch.
Could anybody point me to some documentation where I could find (for example) the connector
pinout (the 20 pin FPC connector). I couldn't find any documentation except the dimensions of
the screen, and in order to wire it to a microcontroller, I need at least the connector layout.
I also bought the USB to SPI interface. There is some software on GitHub, and again there are
no explanations whatsoever about how to use this application.
Background info:
- When I plug the USB to SPI board, it is apparently recognized, so it doesn't seem to be a driver issue.
- When I plug the LCD on the USB to SPI board, the LED on the screen interface board is lit, so I suppose
the connection is right.
Now on GitHub, there are many applications.

As I'm dealing with the 7 inch board, I guess it's here:
Basic-EVE-Demo / EVE Test executabiles / Eve2 / EVE2-70
NB: I verified the chip behind the screen, it's a FT813, therefore EVE2.
There are 3 applications:
As I'm using a capacitive touch panel, I suppose it's this one (TPC = touch panel capacitive).
EVE2_70G_TPC.exe
Running the application does nothing except popping a terminal which says:
Channels found: 1
USB -> SPI bridge opened.
And that's it. But LCD panel or not doesn't change anything.
Could anybody point me to some hardware documentation where I could find the connector
layout, and also explain me how to start the demonstration program?
Thanks for any hint.
