摘要
为提高学生对MSP430系列微控制器的理解和应用能力,提升学生综合运用所学知识的能力,设计了一阶RC暂态过程时间常数测量实验。以MSP430F5529 LaunchPad开发板和LCD BoosterPack插入式模块为硬件平台,利用Code Composer Studio进行软件开发,采用电压极值法对一阶RC电路的时间常数进行实时测量,测量结果通过LCD显示。通过实验,学生掌握了基于CCS平台的MSP430系列单片机的软件开发方法,深入了解了时钟系统、按键、定时器以及PWM,ADC,LCD的原理及应用,进一步提高了综合应用能力。该实验取得了较好的教学效果。
In order to improve students'understanding and application ability of MSP430 series processor and improve their ability to comprehensively apply their knowledge,a first-order RC transient process time constant measurement experiment was designed.Using MSP430F5529 LaunchPad development board and LCD BoosterPack plug-in module as the hardware platform,using Code Composer Studio as software development,the voltage extreme value method is used to measure the time constant of the first-order RC circuit in real time,and the measurement result is displayed on the LCD.Through experiments,students mastered the software development method based on CCS,and deeply understood the principles and applications of clock system,key,timer,PWM,ADC,LCD,further improved the comprehensive application ability,and achieved good experimental teaching results.
