基于MSP430F449的低频波形发生器

Low frequency waveform generator based on MSP430F449

介绍一个利用MSP430单片机输出PWM信号产生的低频波形发生器.频率变化范围（20-200）Hz,频率步进值为1 Hz,输出频率可预置,输出的信号峰-峰值可分别在±10 V-±18 V范围调整,信号波形可预置,数字显示输出波形的频率.

The low frequency waveform generator with PWM signal outputs based on MSP430 is introduced in this paper. The frequency ranges from 20 to 200 Hz; the lowest step is I Hz. The frequency can be pre-configured, the peak-peak value of the output signal changes from 10 to 18 V. The signal waveform can also be pre-configured, and the value of the frequency can be displayed digitally.
