Connect Pi Cable
Insert the Pi cable into the back of the Pi TFT in the correct orientation.
Keyboard + Power
Test the circuit with a USB micro cable connected to the micro USB port on the Raspberry Pi. Connect a USB keyboard to the side of the Pi for input.
The PiTFT should boot up into the Game ROM Aggregator
Remember you have to set up the screen rotation to be 270
so check the previous step if you haven't done that yet!
Lay the D-Pad elastomer gasket over the PCB and place the plastic part on top. Press the D-Pad up and down to test for a solid connection.
Add the rest of the elastomer gaskets and select a game to play test.
Run Mario or something similar to test out the latency. It may be a little difficult to play like this but will feel more natural with the top part on.
