AR Configuration Utility (ARCU) can be used to configure, calibrate, test, and demonstrate both the AR1000 and AR1100 touch screen controllers. Additionally, the AR1100 firmware can be updated (re-flashed) via the ARCU.The AR1000 can use either the I2C, SPI or USART based communication protocols, while the AR1100 can use USB or RS-232 (serial). To facilitate AR1000 communications, USB-based PICkit Serial Analyzer is employed to translate
communications from the host PC to the desired embedded protocol, and visa versa.
