AR1100 touch driver
good day.
i have an AR1100 touch screen controller (https://www.microchip.com/wwwproducts/en/en555168). it works with Linux; however, i can't get it to function with emteria.OS. has anyone had success with this controller?
thanks.

Hi @mountaineer Did you manage to make the AR1100 work ?
Are you using RS-232/UART or USB communication?
copy the file to the appropriate location
/ system / usr / idc

Have you done it ? Does it work well ?
I am using the AR1100 from Adafruit, it is working well on my windows computer. But even with the idc file copied in the good path, it doesn't work with my pi with Emteria.
The system doesn't seem to recognise the touchscreen. It doesn't do anything.
Can you help me get through this please?
I have find out. You have to use the dedicated software from microchip to change the controller's mode.
My controller is working but i have kind of bricked it. So I don't know if it is stuck in HID or digitiser.
Just wanted to add my experience in getting an AR1100 chip to work with Emteria. The trick I found is that you have to put the AR1100 into HID mode in order to calibrate the touchscreen, THEN put the AR1100 into digitizer mode, and it should work with Emteria. I also installed the .ipc file, but I don't know if that file is really necessary or not; regardless, it's not hard to copy to the download folder from a usb stick, then reboot into recovery mode, mount the system, then copy to the system/usr/ipc folder.
I haven't tried, but I did the calibration/mode changes using an old Win7 PC. I think you can do this on a Win10 PC, BUT, once you put the AR1100 into digitizer mode, that's it; you can't get it back out of digitizer mode without Win7 (or a raspberry pi and the github code that apparently fixes it; I haven't tried that).
