这需要掌握一些知识，例如C语言，还有看学习什么硬件，比如单片机还是FPGA，有了C语言知识再去看硬件的数据和例程，慢慢做做练习，就上手了！

　　我分享一个我室友从一个小白到入门的过程吧。

　　虽然我们是计算机科学与技术专业。会偏硬件。但是由于自己没有兴趣就学的不好。直到大四要开始考虑就业。我室友他爸爸给他找了一个硬件的工作。从此开始生撸代码。生撸单片机。因为基础差所以学的比较慢。但是在工作环境中。有人带的情况下。满满的会写一些代码。能玩单片机。虽然现在还是小白但是。总有一天会变成大佬不是么。加油

　　嵌入式板子设计还是相对简单的，因为大部分都是数字芯片，参考芯片手册就行。相对比较难的部分实际上是芯片选型，要综合考虑功能、功耗、是否方便采购等。具体到模块设计，个人认为是MCU与RAM、ROM部分的电路设计比较难，因为各种MCU的读写时序可能不大一样，而且与BSP软件有极高的相关度，稍有不慎就容易设计错误。具体的原理看看《数字电路》《微机原理》单片机类的书就差不多了。题主是做底层软件相关的，感觉入门硬件设计应该不难。 另外，不得不说硬件电路设计很耗钱和时间的，特别是多层板，很考验设计者的细心程度。去年的这个时候我抚摸着成本超过我半年补助的板子，心里感到很惆怅。因为我画错了一个封装。
