Flowcode Support Board

Just uploaded the Flowcode testcard 6 demo into my new RolandTech Enhanced gLCD module and noticed the image has colour inversion. The easy fix is to go into the Flowcode properties for the gLCD and change the colour inversion switch from No to Yes (or from Off to On can’t remember exactly now), and recompiled and reprogram. Easy fix BUT should I need to do this? Is there something else Im missing? Just wondering why the module inverts the colours with the demo code as published by Matrix? Anyone have the answer?
Thanks

Hi Charles,

The latest displays have an IPS screen which has an inverted colour. The older version just had a standard LCD which was good but not as nice as the inverted IPS version.

Ah ok. That explains it. Many thanks.
