CS5460芯片在MSP430单片机中的应用(Application of CS5460 chip in MSP430 single chip microcomputer)

说明：  基于51/52单片机 1，探测环境温度，以LCD1602 做显示单元 2，可设置上限/下限数值，从而做到警报的提醒及应急设施的启动 3，超过设置限值时，会启动 LED 、蜂鸣器以及电机（仿真时使用）应用可使用其他代替(Based on 51 / 52 single chip microcomputer 1. Detect the ambient temperature with LCD1602 as the display unit 2. The upper / lower limit value can be set to remind the alarm and start the emergency facilities 3. When the setting limit is exceeded, the LED, buzzer and motor (used in simulation) application will be started, and other alternatives can be used)
