如果我的音量的调高（即负载增大），我的DCDC的5V输出会跳变到3.9V以下(12V适配器）。想问下有没有遇到类似情况的，需要怎么改善？快出现个大神来解救一下。

大家好…我是一个完整的绿色棒在这一切…我在阅读、阅读和阅读…尝试……但没有任何意义我…我有一个ASM文件称为正常。我在PC上装载了MPLAB 8.92…你可以得到正常的.ASM文件…微芯片网站…从AN64…我在扫描互联网后发现了这个文件…因为它确实…或多或少…我想要的……所以我写了另一个解码程序…使用流代码…它的工作大约92%的时间。矿井不做实际…代码跳跃。例行公事…我只是绕过那部分…嗯，现在我找到了这个汇编文件。我有一个PIC16F57芯片。（看两个数据表。“56”和“57”。看起来几乎一样。Boin插销）.No.ASM文件中有一些代码行。我只是摸不透…（我需要让它正确编译……）所以有“$”的迹象。在等式声明中…对我来说，他们似乎是…像假的等同…只是为了让作者能把文件拿到光盘上。我希望我能找到一个人。告诉我…这一切意味着什么…（我有个主意…但需要有人来澄清我的想法…请……我也想改变…这个NORMAL.ASM文件。转到另一个小芯片。比如说16F68…首先…任何人…有兴趣帮助…拜托。？我完全被困在这里了我是一个职业科学家。只需要做些事情…这样我就可以达到我的一些任务的实际终点。为了完成整个项目，所以我对PIC汇编语言有一定的了解。是零…正如我所说的…我必须通过它。为了使项目的其他部分完成…任何帮手…拜托。。？？？？拜托。。？？？？最善良的南方非洲。 以上来自于百度翻译 以下为原文 Hello folks... I am a complete GREEN STICK in all of this.... I am reading and reading and reading... and trying....BUT nothing makes any sense to me..I have an ASM file called NORMAL.ASM... and I have MPLAB 8.92 loaded on the PC...You can get the NORMAL.ASM file... of the Microchip website.. from AN642 ... I found this file after scanning the internet... because it does... more or less ... kind of what I want ...So I have written another decoding program... using FLOWCODE... and it works about 92% of the time.. Mine does not do the actual.. code hopping.. routine.. I just bypass that part.. hmmm.. So now I have found this assembler file.. and I have a PIC16F57 chip.. (looking at the two datasheets.. the '56 and the '57.. look almost alike.. bar the pinouts)..There are some line of coding in the NORMAL.ASM file.. I just cannot fathom out.. (I need to in order to get it to compile correctly...)..So there are '$' signs.. in the EQU statements.. To me they appear to be.. like fake equates.. just so that the author can get the file to disc.I wish I could find someone.. to tell me.. what this all means.. (I have an idea.. but need someone to just clarify my thoughts.. please)..I would also like to transmogrify .. this NORMAL.ASM file .. over to another little chip.. say like a 16F684 ... to begin with.. ANYONE... interested in helping... please.?? I stuck here completely..!! I am a lay scientist.. and just need some things done.. so that I can reach the actual endpoint of some of the tasks I have.. in order to complete the whole project..So my knowledge of PIC assembler.. is ZERO.. as I say.. I have to get through it.. to get the other parts of the project done.. Any helpers... please..??? please..???Kindest Regardscardacsouth africa..
