IMX RT 1052 GT911 Touch Driver

[ap213]

Hello dear all,

Before I sit down and write my own driver for the widely used GT911 Touch Driver, I was wondering if somebody doesn't have one and is willing to share it? I need basic functionality to destinguish between kTouch_Down, = 0, /*!< The state changed to touched. */, kTouch_Up = 1, /*!< The state changed to not touched. */, kTouch_Contact  /*!< There is a continuous touch being detected. */ and getting the coordinates of the touch event. 

Best Regards.

Hi @ap213 ，

   We don't have the directly GT911 driver, but you can find the GT911 driver, and modify it to match the RT1052, as you know, our SDK already provide the I2C driver.

  I search the community, and find some post may useful to you:

 You just need to find the GT911 driver, to the I2C, you can refer to the RT1052 SDK I2C code.

Wish it helps you!

Best Regards,
