As a follow up from my previous post Getting Waveshare TFT working on Raspberry Pi, my display was blanking out (turning off) after a few minutes. While this is preferable to conserve power and to prevent the display from spoiling, it will be necessary for my projects to be able to turn the display on on demand to display the information before turning if off automatically again. To that end, I will be using the following approach to turn the display on demand.
For some projects, having a display for the Raspberry Pi is necessary to help convey what the Raspberry Pi is currently doing.

Getting them to work on the latest Raspbian Jessie was really easy as opposed to the Wheezy versions. Below are the steps I used to get it working.
