您好，我已经在SPDIC33 EP512MU810 PWM工作精细探索16开发和我的定制板。但当我尝试端口toDSPIC33 EP256MC506相同的代码不工作不能产生PWM。我使用相同的8MHz振荡器。其他外围设备，如LED，开关，定时器工作良好。即使在代码中没有任何错误。请更新…如果任何人都有一些想法…编辑：我已经看到例子16-1：PWMX写保护寄存器解锁序列可能是这是失踪的FordSpEP3EP256MC506in矿山代码TS9

But When I am trying to Port to dsPIC33EP256MC506 same code does Not worked Not able to generate PWM . I am using Same 8MHz Oscillator . Other peripherals such as LEDs, Switches, timers are working Fine.

If any body have some idea.. Edited : I have seen EXAMPLE 16-1: PWMx WRITE-PROTECTED REGISTER UNLOCK SEQUENCE May be this is missing for dsPIC33EP256MC506 in Mine Code -- TS9

尝试告诉我们“……不工作[Sc]不产生PWM……”实际上意味着。我假设“……在代码中没有任何错误”意味着编译器不会产生任何错误。你对旧的MCU和你使用的PWM模块之间的差异做了哪些研究？在新的使用？苏珊
以上来自于百度翻译 以下为原文 Try telling us what "...does not worked[sic] does not generate PWM..." actually means. I assume that "...not getting any error in code" means that the compiler does not generate any errors. What research have you done into the differences between the PWM module you use in the old MCU and the one you use in the new? Susan |

您是否考虑过衍生工具之间的PPS/端口设置的最终差异？6X和100针之间有显著性差异。
以上来自于百度翻译 以下为原文 Did you consider eventual differences in the PPS/port setup between the derivatives? There is a significant difference between 6x and 100 pins. |
