GT9271 chip?

Open sandric opened this issue 5 years ago • 4 comments

Hi, I kinda new to touch panels world, is there was any tests for GT92* chips? I'm looking into playing with https://www.buydisplay.com/default/10-1-inch-capacitive-touch-panel-with-controller-gt9271-10-point-multi-touch touch panel in my project, I wonder if I'll get any luck connecting it to arduino or esp32?

Hi, You can try this lib. It is possible that main control registers on GT92* is the same. Unfortunately can't find any datasheet with registers description for GT92*.

Hi @nik-sharky,

I'm also looking for a driver for the GT9271. The datasheet is at the bottom of the link provided by @sandric .

@nik-sharky @sandric Any luck getting this to work with the GT9271? I was hoping to use it with this touch panel. https://www.buydisplay.com/9-inch-capacitive-touch-panel-with-controller-gt9271-10-point-multi-touch

There is a datasheet for the GT9271 with the register map available at https://dl.linux-sunxi.org/touchscreen/GT9271%20Datasheet.pdf, though it is in Chinese.
