Hi,
I've been making a 3D printed mini laptop with a raspberry pi zero W and am using a PITFT for the screen.
I need to use as few wires as possible to go across the hinge from the screen to the PI and cant fit a ribbon cable attaching all the GPIO pins.
I've looked at the documentation for the PITFT on the pin outs and found that it uses the pins SCK, MOSI, MISO, CE0, CE1, GPIO25, GPIO24 and both the I2C pins. But whenever i plug these pins in using some small jumper wires the screen works but the touch doesn't.
I've been searching for its pin outs and keep getting the same results and when plugging the PITFT straight onto the raspberry pi the touch works again.
Is there any extra pins used for this type of PITFT that went documented?

Have you also connected the 3.3v pin? The STMPE610 touchscreen controller has a pull-up resistor connected to 3.3v on its interrupt pin:

Yes, i have connected the 3v pin opposite the first 5v pin.adafruit_support_mike wrote:Have you also connected the 3.3v pin? The STMPE610 touchscreen controller has a pull-upi resistor connected to 3.3v on its interrupt pin:

Post a photo showing your hardware and connections please. 800x600 images usually work best.
