Ghost Touch

Post by Haz »

I am working with the 43A GTT, in UART mode. Everything works well, but I have a few questions.

1. What are the best practices for the images used on screens to make the startup time faster. Right now, I am looking at 3s (I have some graphics). If there is a way to modify the images to speed up, that would be great. I can change any of them to a different format, type, etc...

2. I have a ghost touch and I have no idea why. It is fully repeatable. Is there a way I can send a GTT_Designer project for someone to look into it? I am at a loss trying to find it.

Hi Haz,

The display is loading all images (and decoding them at the same time) at startup. And the more image you have, the longer it takes.
Using *.bmp images will be faster than other formats as they hardly need to be decoded.

I received your GTT Designer Project file, I will update you when I get to replicate and find a solution.
