Library for GT911 touch sensor?

I've been looking for a library for the GT911 touch sensor. (Currently T3.2, Soon to be T4.0) I'm not having a lot of luck. Everything I've turned up so far has been specific to whatever they wrote it for. I'm sure people have been down this path. Anyone know of one that works for a Teensy?

I didn't see one in the included files from Teensy.

Thanks!

Yes a simple web search.

But, you also need to be able to sort out what ones are useful and what ones are not. For things like this, totally new hardware, I'm not so hot. It's yet another time consuming learning curve. I found a bunch that needed unknown amounts of work to make something I could use out of them. I'd finally got to the point of looking for the chip documents to see what made it go. Could I roll my own library? Or at least, learn enough to be able to adapt one of the ones I found? Also a daunting learning curve.

This is why I'm so grateful that you found this one. It may be a simple web search to find. It's far more to know which one that you found makes the most sense to try.

Glad I found the right thing - GT911 touch sensor - was the first thing to figure out without a link to what it really was that would have helped.

It is a very large surface as pictured and not clear that was the device at hand. So, it was a double guess on the device and that the ESP code was complete to work.
 
The device I have, that includes this chip, is a DFRobot #0669 340x480 cap touch TFT. All I knew is it included a GT911 touch sensor. And, I'm not really a fan of the ESPs. So there was a lot of finger crossing when I tested it. Currently wrapping what you found, up with the ILI9488_t3 stuff, into a combined library for this display. (It'll only be single touch. I don't feel like going into "gestures" today.)
