自己编写的基于dsp2812的spwm波程序，通过RC滤波能看出正弦波-Their own written procedures based on dsp2812 of spwm waves through the RC filter can be seen sine wave

在使用TI公司DSP2812编程时，设计到浮点向定点转化的需求，本代码以实现三相桥式逆变器SPWM调制为例，介绍一种简便的浮点定点转换方式。(n the use of DSP2812 programming in TI company, the demand of floating point conversion to fixed point is designed. This code is used to realize three phase bridge inverter SPWM m
