Dennis ODea

I called tech support and was connected with Charlie Matthews. My question needed a bit of research, and Charlie completed the research and sent me a written summary in less than an hour. I told him it was not an emergency situation, but he responded very quickly. Excellent customer support!

Update 10/10/23: Charlie also sent us a no charge sample next day that we were quickly able to test to confirm we would not have any issues in our product. Could not be happier with the support provided.

Sergey Dryga

Excellent support, fast response and they provided information requested and helped tremendously with both design and firmware.

Mark Courson

Kelsey Zaches has provided us with timely information. She facilitated a meeting and answered all questions and provided us with alternatives. Highly professional, personable, and most important, technically savvy.

Enda Sullivan

The support was excellent. It would be good to have a fully functioning software suit that works in Windows but cftest was sufficient just to get started.

Mike Gorden

Charlie didn't give up on me and pursued the issue until it was resolved. He also insured that the datasheet was corrected.

Mario Munoz

I really appreciate the quick answer to my question

Peter Glen

Quick response, thank you; The solution was that the chip we are using is little endian, and the display is big endian. Swapping the ushort_16 byte order did the trick.

Very prompt and thorough reply from Chris Mathews of Crystalfontz. Unfortunately their 3.5" TFTs are not tested w/ Pi Zero W. But they offered to review our code, which is nice. Will probably go that route if no plug/play solution is available on market.
