Increased Frame Rate on a cheap Raspberry Pi LCD - Make Your SPI Display Playable

Описание: There are a number of cheap LCD screens for your Raspberry Pi. If you're just using them for a control panel or mobile desktop the default settings can work fine. But if you want to play games or any sort of video or animations the 5 frames per second just won't cut it!

In this video I'll show you how to set up an LCD screen for a mobile games console project. We'll install the default drivers and then tweak the settings to get to a useable frame rate. I'll also show some of the issues you'll come across as you push the SPI channel too far.

This is the first of 2 videos on tuning your LCD display. The second shows you how to replace the default drivers with much better ones to get even better frame rates.
