Alarm control panels are a part of almost everyone’s daily life, either at home or at work. This application note describes a sample alarm control application using the MAXQ2000 Low-Power LCD Microcontroller, created with the MAX-IDE development environment. The MAXQ2000 can be easily interfaced to peripherals typically used in security applications, including LCD displays, PIN entry keypads, piezoelectric horns and buzzers, and magnetic reed switches.
