Setting up touchscreen: Raspberry Pi drive recorder with GPS logger

Since PiTFT itself is already setup in the last step, now I continue to setup touchscreen. This step is also documented on the official document so you should read though this first.

Basic setup

To start with, we make udev rule for the touchscreen.
Then remove and re-install touchscreen package. Then check if current setup went O.K. Now touchscreen should refer to eventN where N is number.


Before calibration process I installed some handy tools that were introduced on the document.


I installed mplayer for later preview use.
I downloaded video from and played it with the code below, which is exactly the same as documented.
Then I saw some scary message. I'll have to check this out later. I'm just going to add GPS module and see if it works.
