Hardware rotate display preferable

[nikthefix]

Running the display in native portrait mode is much faster than using the soft rotate function for landscape. The hardware rotate for landscape is much better and just as fast as portrait but for some reason the endianess switches for colour byte order:

Native portrait - MSB first Hardware landscape - MSB first SoftRotate landscape - LSB first

Also, for hardware landscape the display buffer is shown twice but squashed. Could lilygo add the DXQ1D1001 / JD9613 datasheet? Should the driver files in the repo be renamed from GC9107 to JD9613?

A patched TFT_eSPI demo - like you did for the T-Display-S3 would be welcome for those not using LVGL. I think these new lilygo amoled boards are wonderful! Thank you for making them. Nik

Thank you for your support to LilyGo. The initial version of the code was written by @mmMicky. He has already left. The promotion of TFT_eSPI may need to be promoted by the community. I can't deal with more things at the moment.

Hi Lewis, I now have a working version of TFT_eSPI for T-Display-Amoled and T-Track. I will post to github when I've cleaned it up a bit.

Thanks

BTW Lewis, I'm happy to contribute to lilygo demos etc but I'm not sure of the best way to submit my code and ideas. Should I use github or send files directly to you? I'm a big fan of lilygo products as you can tell as I'm always leaving messages on github. I have a lot of embedded experience as I worked for Roland Corp Japan for 25 years, but mainly working in China - Shanghai and Chengdu for the Roland / Boss joint ventures. I'm based in London and concentrate on open source hardware dev.

Please let me know if I can be of help.

Additional:

I've been in touch with a Youtube contributor (Volos Projects: @.***). He has helped to make the T-Display-S3 and other lilygo products so popular through his enthusiasm and spectacular demos / videos. No doubt you are aware of his work. We both thought that the lack of example code support for TFT_eSPI or Adafruit GFX in the case of the new amoled boards (now including amoled Touch-Bar) could alienate Arduino and PIO users who don't use LVGL, and that as a matter urgency, some simple effective demo code should be provided for these other frameworks. Community support will no doubt offer a variety of solutions but it doesn't always find itself to the 'hub' and takes time to filter through. So I refer you to my previous email.

Excellent, thanks for the Datasheet!

OK Lewis, I'll do that. Many thanks.

Additional:

A couple of weeks ago I contacted the manufacturer of the display used in the T-Track (they were very nice to deal with) and got hold of an earlier version of the datasheet. It seems that this display does not support a vertical scan so a hardware landscape is probably not possible, which explains why mmMickey implemented the soft rotate. So please ignore my previous message about landscape mode. For speed it's easy enough to design a gui in portrait at a 90 degree angle.
