So first off i originally thought i could use an ar1100 to act as a touchscreen for my 7" HDMI lcd screen. However after trying the Vendor_04d8_Product_0c03.ics file in /system/usr/idc folder and rebooting i still can't get it too work. A lot of people can't get it to work so I figured it can't be use with android 4.3 as it stands.
When i plug it in the debug window shows
usb 2-1.2: new full speed USB device number 5 using fsl-ehci
input: Microchip Technology Inc. AR1100 HID-MOUSE as /devices/platform/fsl-ehci.1/usb2/2-1/2-1.2/2-1.2:1.0/input/input3
generic-usb 0003:04D8:0C02.0004: input,hidraw0: USB HID v1.11 Mouse [Microchip Technology Inc. AR1100 HID-MOUSE] on usb-fsl-ehci.1-1.2/input0
but the touching the panel does nothing. Not in app, or out. The screen works fine on my windows machine.
My question is how can i interface a 4 wire resistive touch screen? I don't mind if i have to use i2c or whatever it takes but i don't know where to start. i noticed some people are useing the lvds as a hdmi out to go to laptop screens but no one ever discusses getting the touchscreen to work. Or at least in any writeup/ tutorial i could find.
Some background on my project is that i want to use this to have a 7" touchscreen in my vehicle that runs android software and also software i will create to control electronics in the car. I have everything i need except for a touchscreen.
Linux won't work very well because it's not touchscreen friendly at the moment. (pop up keyboard, email apps, etc.) Maybe once ubuntu makes thier phone software it will be a better option but for now I need android to work.
Any ideas how to get a 4-wire resistive touch screen to work with android? I can compile from source if i have to i just don't know what to edit.
