ERB-112 主控板

在很多人眼里，主控板上有密密麻麻的芯片引脚和PCB布线，看起来难度很大。其实恰恰相反，主控板的设计有其独特的设计规律。事实上，它就像积木一样。在满足单片机最小系统要求的条件下，需要什么功能只需要增加相应的电路模块即可，这种设计思路也可称为模块化设计思想。

本文将从三个层面介绍机器人主控板的设计思想。它们是:

主控板最基本部分的基础、设计和原理;

分支、主控板功能模块扩展及设计思路;

最后，计算出主控板中各功能模块的具体电路参数。

我将带您体验使用大树的层次结构作为模型的电路设计的乐趣。

基金会
这里是单片机最小系统的基础，是单片机能正常执行程序的最简单的工作环境。没有这些，单芯片无法运行程序。

最小系统由电源电路、时钟电路和复位电路组成。大多数芯片都有一个最小的系统，包括所有这三个电路，而一些芯片不使用外部时钟，可以使用内部RC振荡器为程序运行提供时钟参考。

In many people’s eyes, the main control board has a dense chip pins and PCB wiring, it looks very difficult. In fact, on the contrary, the design of the main control board has its own unique design rules. In fact, it is just like building blocks. Under the condition of meeting the minimum system of the single chip microcomputer, what functions are needed only need to add relative circuit modules, which can also be called modular design idea.

In this paper, I will introduce the design idea of robot main control board from three levels. They are:

Foundation, the design and principle of the most basic part of the main control board;

Branch, main control board function module expansion and design ideas;

Leaves, calculation of specific circuit parameters of functional modules in the main control board.

I’m going to take you through the joys of circuit design using the hierarchy of a big tree as a model.

foundation
Here is the foundation of the single chip microcomputer minimum system, is the single chip microcomputer can normally execute the program of the simplest working environment. Without these, the single chip is unable to run the program.

The minimum system consists of power circuit, clock circuit and reset circuit. Most chips have a minimum system that includes all three of these circuits, while some chips do not use an external clock and can use an internal RC oscillator to provide a clock reference for the program to run.
