有人能告诉我PIC32 mm的软替换（）是否正确替换？看起来SoftReset来自传统的PLIB。我正在尝试重用旧的PIC32MX代码，并且看起来PLIB不支持PIC32MM。我发现一篇文章推荐PIC32MZ的_u pic32_._reset()替代方案，但是我不确定这对PIC32MM是否正确。谢谢
以上来自于百度翻译 以下为原文 Can someone point me to the correct replacement of SoftReset() for PIC32MM? It looks like SoftReset is from legacy PLIB. I am trying to reuse old PIC32MX code and looks like PIC32MM is not supported in PLIB. I found one post that is recommending __pic32_software_reset() alternative for PIC32MZ, but I am not sure if this is a correct for PIC32MM Thank you

这就是我在MX和MZ上都用到的，并且可以工作：编辑：如果内存提供服务，在执行上面的代码之前，您需要解锁序列。
以上来自于百度翻译 以下为原文 This is what I use on both MX and MZ and works: RSWRSTSET = _RSWRST_SWRST_MASK; RSWRST; while(1); Edit: if memory serves you need the unlock sequence before executing the code above. |

谢谢你的回复。我实际上在MX手册中找到了类似的序列，只是不确定如果在PIC32 MMHTTP://WW1.MICCHIP.CON/DeLoSs/En/DeVICECD/61118B.PDF页11中工作的方式是相同的，除了解锁之外，它还需要同时或4个NOP。
以上来自于百度翻译 以下为原文 Thank you for reply. I actually found the similar sequence int the MX manual, just not sure if this works the same way on PIC32MM http://ww1.microchip.com/downloads/en/DeviceDoc/61118B.pdf page 11 In addition to the Unlock, it requires while or 4 NOPs at the end as well /* perform a system unlock sequence */ SYSTEMUnlock(); /* set SWRST bit to arm reset */ RSWRSTSET = 1; /* read RSWRST register to trigger reset */ volatile int* p = &RSWRST; *p; /* prevent any unwanted code execution until reset occurs*/ while(1); |

实际上我尝试了_u pic32_._reset()，我在最初的文章中提到过，它也可以工作。我找到了另一本手册，它涉及整个P32家族，并且如果具有类似的序列：http://ww1.micro..com/...eviceDoc/60001118H.pdf。
以上来自于百度翻译 以下为原文 I actually tried __pic32_software_reset() that I mentioned in the initial post and it works as well. I found another manual that refer to the whole P32 family and if has a similar sequence: /* The following code illustrates a software Reset */ // assume interrupts are disabled // assume the DMA controller is suspended // assume the device is locked /* perform a system unlock sequence */ // starting critical sequence SYSKEY = 0x00000000; //write invalid key to force lock SYSKEY = 0xAA996655; //write key1 to SYSKEY SYSKEY = 0x556699AA; //write key2 to SYSKEY /* set SWRST bit to arm reset */ RSWRSTSET = 1; /* read RSWRST register to trigger reset */ unsigned int dummy; dummy = RSWRST; /* prevent any unwanted code execution until reset occurs*/ while(1); http://ww1.microchip.com/...eviceDoc/60001118H.pdf |
