本帖最后由lupeisen于2021-5-2310:01编辑我们在使用单片机的PC6跟PC3的内部PWM输出功能进行半桥驱动，发现功耗接近0.7W，这个正常的吗，导致了5V的LDO也发热量大，这个能通过软件来进行降低功耗吗，有没有大神遇到相同问题的，请指教下，谢谢

主频8Mhz或16Mhz，使用的PCKIT3.5，已排除接线等故障，显示thefollowingmemoryregionsfailedtoprogramcorrectly:programmemoryAddress:00000001expectedvalue0000118areceivedvalue:00000000programmingfailed.请问各位专家，此故障是什么原因所致，如何克服，谢谢！

模电难在运放为此有人将其称为魔电面对种类繁多的运放电路如何能在第一时间看出其作用还望各位坛友能分享一下绝招例如在输入为音频信号时下面的电路是何工作原理

本帖最后由hsxs于2020-11-1010:33编辑之前没有接触过PIC的单片机因为工作的需要，使用PIC12LF1501,今天查了一遍网上的教程，安装好IDE和编译器之后，新建了一下工程，编译始终出现这个问题，换过老的版本V5.00，也是这个样子CLEANSUCCESSFUL(totaltime:25ms)make-fnbproject/Makefile-default.mkSUBPROJECTS=.build-confmake[1]:Enteringdirectory'D:/PIC/demo/demo.X'make-fnbproject/Makefile-default.mkdist/default/production/demo.X.production.hexmake[2]:Enteringdirectory'D:/PIC/demo/demo.X'"C:\ProgramFiles\Microchip\xc8\v2.31\bin\xc8-cc.exe"-mcpu=12LF1501-c-fno-short-double-fno-short-float-O0-fasmfile-maddrqual=ignore-xassembler-with-cpp-I"C:/ProgramFiles/Microchip/xc8/v2.31/pic/include"-Wa,-a-DXPRJ_default=default-msummary=-psect,-class,+mem,-hex,-file-ginhx032-Wl,--data-init-mno-keep-startup-mno-osccal-mno-resetbits-mno-save-resetbits-mno-download-mno-stackcall-std=c99-gdwarf-3-mstack=compiled:auto:auto-obuild/default/production/main.p1main.cmake[2]:***Error1terminatecalledafterthrowinganinstanceof'std::invalid_argument'make[1]:***[.build-conf]Error2what():Nosuchfileordirectorymake:***[.build-impl]Error2error:clangfrontendcommandfailedwithexitcode3(use-vtoseeinvocation)(908)exitstatus=1nbproject/Makefile-default.mk:105:recipefortarget'build/default/production/main.p1'failedmake[2]:Leavingdirectory'D:/PIC/demo/demo.X'nbproject/Makefile-default.mk:90:recipefortarget'.build-conf'failedmake[1]:Leavingdirectory'D:/PIC/demo/demo.X'nbproject/Makefile-impl.mk:39:recipefortarget'.build-impl'failedBUILDFAILED(exitvalue2,totaltime:1s)
