Video Not Working? Fix It Now

In this video I look at the new 7 inch LCD panel from Elecrow with a built in ESP32 and fast RGB interface. Running a 800 x 480 pixel display from a microcontroller can lead to slow screen updates, but not with this new 16 bit parallel interface. Find out how well it works and how we can optimise the screen refresh code to complete full screen refreshes at 30 fps.
