When should I install the AR1100 driver?
The only reason to install a driver is for calibration. The OS can recognize touch out of the box for both mouse and digitizer modes. After that, you have two options for further configuration:
- Use our configuration/calibration utilities (on the website)
- Use the UPDD driver to calibrate.
The Microchip mTouch™ ARxxxx Series Resistive Touch Screen Controllers are not recommended for new designs. Visit microchip.com/touch for our latest products.
