用DSP中的全比较器产生六路带死区的PWM波-DSP comparator six dead-band PWM wave

无霍尔传感器无刷直流电机控制源代码，控制I芯片为DSPIC33FJ32MC204,主要特点为无需过零比较器实现换相，很好用。-Without Hall sensors brushless DC motor control source code control I chip DSPIC33FJ32MC204, main features without having to achieve zero-crossing comparator commutation, very good use.

高分辨率脉宽调制，通过增加比较器的位数提高分辨率。用在系统时钟高于100MHz而要求PWM分辨率高的场合，TMS320F2802有这个增强PWM模块，可以查看相关的用户手册。-High resolution pulse width modulation, the comparator improve resolution by increasing the number of bits. 100MHz system clock with higher and higher resolution
