Connecting the Display to the Pi Hardware Connection The 4DPi-35 is easily connected to a Raspberry Pi, by simply aligning the Female 26 way header with the Raspberry PI’s Male 26 way header, and connecting them together – ensuring the aligning is correct and all pins are seated fully and correctly. Image and which to apply this kernel to that.

If you see less than 5 targets, then for some reason you have triggered multiple signals for a single touch, and you should repeat the process from step 6 again. kernel=kernel_hat.img Save the changes made to /boot/config.txt. 6) Shutdown the Raspberry Pi safely, and remove the power.
