TFT Displays

A generous soul donated a handful of very hard to develop for TFT displays, the GEN4-IOD-24T from 4D Systems. They need some extensive setup to work with unfortunately, but once mastered, can be quite powerful! They even have a touch display!

Much of this guide was thanks to the work of Silvia Rothen on their blog post about this display, & the work of both Citybadger & Tristan!

This drive ^ has just one partition, but if there are multiple, you'll need to select and then delete every partition.

DiskPart succeeded in creating the specified partition.

Then exit diskpart back to command promt.

DISKPART> exit
