Getting Started with the MAX1233/MAX1234 Touch-Screen Controllers

This application note shows how to exercise the features of the MAX1233/MAX1234 touch-screen controllers. A simplified console menu system is provided that allows direct, low-level access to the MAX1233/MAX1234 device registers. Each register read or write operation uses 32 SPI clock cycles. The software uses short, mnemonic names for each register. When used with the MAX1234 evaluation kit (EV Kit) board and the MINIQUSB+ command module, this software allows maximum low-level control. Full source code is provided in the accompanying zip file.
