Greetings to all. I hope that we face the current situation at the door as best we can in the company of loved ones. I hope that soon we can return to normality with a better spirit and better prepared for the future.
James, thanks for continuing to inspire those of us who are just fans of this TFT world with these fantastic EVEx chips, with only a didactic and experimental purpose for free time.
First of all I share the link of the version of the library for gameduino, that we have been working in the team next to my brother ligthcalamar (Spain); It works with the teensy 4 SDIO reader, using Griman's SdFat beta library for multimedia management, using screens such as the 3.5 ", 4.3", 5 "and 7" NHD, Riverdi 5 "and 7". Even with the EVE2-38, EVE2-50G and EVE3-50G Matrix Orbital ones.GD23ZUTX
It also works on ARM boards like the F767 core or the H743 core, using the official STM32 core in the arduino IDE.
I have some doubts that I wish you could guide me.
Some displays like the EVE 2-38G or EVE 2-50G have Goodix GT911 touch chips installed. According to the selection guide AN_336_FT8xx-Selecting-an-LCD-Display.pdf
We must upload the information regarding the GT911 touch chip during the start phase, to activate the touch screen.
Inside the file GD23ZUTX.ccp line 718, there is the matrix (EVE_GT911_data ) in which are the registers that must be written during the start of the screen, however the question I have is: What instructions should be used to write that information on the FT813 chip?
Waiting for your comments. Cheers
