PWMDAC
This module converts any s/w variables into the PWM signals in EPWMxA/B for C2000 MCU.
Thus, it can be used to view the signal, represented by the variable, at the outputs of the PWMxA, PWMxB, pins through the external RC low-pass filters.
请问一下,我要在28027F里面观察观测到的转子位置信号,应该怎么设置,?
28027F有六路做驱动信号驱动电机,那么只有剩下的PWM4A和4B了,PWMDAC输出的时候只能配置这两路了吗?
RC滤波器是需要自己外接吗?应该接截止频率多大的RC?

TI的文档中有给一个推荐参数,2K的电阻和0.1uF电容,截止频率差不多800HZ

哦,哪个文档啊,能麻烦给我发个地址吗,还有我想用epwm4A和epwm4B作为PWMDA输出,程序里面相应的应该怎么改啊?麻烦指导一下,程序有些乱看不太明白。
