4 wire touchscreen

Other Hardware Displays
1

Hello, I'm currently trying to use a touchscreen that has 4 wires but 8 pins. I have a connector with 8 outputs, but I read some topics about touchscreens and everybody uses just 4 of them. So, right now, I'm using just 4 pins (It works with some noises) and my question is: If I use the 8 pins it will be better? If yes, how to connect them?

Here is the touchscreen model: https://www.digikey.com/product-detail/en/nkk-switches/FTAS00-104AS4/360-3037-ND/4508087

I'm putting the screen configuration and the code as attachments too.

That touchscreen is 4-wire only, it just happens to have an 8-pin connector with pairs of pins connected together.

On your board, shorting the pairs of pins 1-2, 3-4, 5-6, and 7-8 will make the connection to the flexy thing a bit more reliable (because there's 2 connections to each signal).

If you look real close you'll probably see each track on the flexy split into 2 pins

Yours,
