通过PPS无法获得MCCP输出?

嗨,我试图使用MCPP作为PIC24FJ1024GB610上的半桥输出,但是如果我正确读取数据表,我就不能重新映射OCMXY管脚(即OCM1A和OCM1B等)。这是正确的吗?您可以重新映射较旧样式的输出比较引脚,但是我想使用MCCP外围设备中发现的半桥PWM输出。

    Hi, I am trying to use the MCCP as a half-bridge output on a PIC24FJ1024GB610, but if I am reading the datasheet correctly I can't re-map the OCMxy pins [i.e. OCM1A and OCM1B etc]. Is this correct?

You can re-map the older style output compare pins, but I want to use the half-bridge PWM output as found in the MCCP peripheral.

OCM1X引脚有点可重新映射为单PWM输出引脚的一个子集OCM1A - OCM1F,作为对OCM1A/B-OCM1E/F.我不确定全桥模式,使用4针。

    The OCM1x pins are somewhat re-mappable as single PWM outputs for a subset of pins OCM1A -OCM1F, as pairs OCM1A/B - OCM1E/F.

I am not sure about the full bridge mode that uses 4 pins.

您对“OCM1A和OCM1B2”引脚正确,但其他OCM引脚是PPS(不是全部)。PPS只是检查外围输入源和输出源的列表。如果未列出,则预先分配给PIN。Yorky

    You're correct about the "OCM1A and OCM1B2" pins but other OCM pins are PPS (not all).
With PPS just check the lists of peripheral INPUT SOURCES and OUTPUT SOURCES. If not listed, they are pre-allocated to pins.
