MCS-51和MSP430单片机定时器的应用比较

以单片机产生PWM波作为实例,对MCS-51单片机定时器T0和MSP430单片机的TimerA进行了比较,得知MCS-51单片机定时器T0结构简单、入门容易、使用方便,但功能较弱,对编程技巧要求较高,而MSP430单片机的TimerA结构复杂、功能强大、入门不易,但使用灵活,对编程技巧要求不高,从而建议用户应根据自身的知识基础和应用场合来选择单片机实现定时的功能。

Application Comparison of Timer in MCS-51 and MSP430

Taking the example of producing pulse width modulated wave by single-chip microcomputer,Timer0 in MCS-51 single-chip microcomputer and Timer A in MSP430 single-chip microcomputer are compared,and it is known that Timer0 in MCS-51 single-chip microcomputer has the following characteristics：the structure is simple,the introduction is easy and the usage is convenient,but,the function is not strong and the demand of programming skill is high,and Timer A in MSP430 single-chip microcomputer has the following characteristics：the structure is complex,the function is strong and the introduction is not easy,but,the usage is flexible and the demand of programming skill is not high,thus,it is suggested that the users should select single-chip microcomputer to implement timing function in the light of their own knowledge foundation and application situation.
