I'm going to buy one of this IR touch panels, the 14.1'' version if that matters.
I want to replace its controller and make my own. The goal is to retrieve the status of all the pixels. It's for a custom application with an ESP32, I don't need a Windows driver, etc... just read the sensor's matrix and acquire the pixel status.
Is there any project that I can study and "fork"? Just to avoid to reinvent the wheel from scratch...
It appears you are taking the right approach by researching thoroughly before purchasing. This careful step can help you avoid potential issues. However, these statements in the ad raise some red flags for me:
The brand name is ICAR 35 and it is universal, meaning it should be compatible with various brands.
Certainly, it has a model number which is usb touch sensor lap.
Thanks for your answer, but honestly I'm not sure to get it.
I'm not looking for a library or code for this specific model. That was just an example of what I'm going to buy, i.e. a 15'' IR touch panel.
I'm looking for general information about how to control at low-level such a device, without its own controller. I bet they (the touch panels themselves) are quite similar: a matrix of excitement and sensing signal, don't they?
By getting the controller for the device, you can discover how to duplicate all the low level control! Then make your own. By having the original you can switch back and forth to discover your errors!
Of course, that's exactly what I'm going to do!
But it is not my question, actually
