摘　　要：分析了利用MSP430的Timer_B在比较模式下输出脉宽调制(PWM)波来实现D/A转换的工作原理。介绍了利用MSP430F449的TimerB的PWM输出来产生正弦波和直流电平的方法 。The principle of utilizing the PWM to realize D/A when the MSP430 Timer B is working in compare mode is analyzed. The method to use the PWM of MSP449F449's Timer B to create a sine wave and a DC level are described. At last,the corresponding hardware circuit and C language program are given.

关 键 词：MSP430 Timer_B 脉宽调制 PWM D/A转换 C语言源程序
