2 -arduino、arm、树莓派、单片机四者有什么不同?-

3 -单片机可以替代PLC么?-

4 -单片机有没有必要用汇编讲?-

5 -相关课程-

单片机和C语言,是自动化(机器人)学科重要的基础内容。

如果对机器人感兴趣,可参考机器人工程师学习计划

课程学习动机~Why?为什么学习单片机编程?

单片机方向就业?把握市场需求!

软硬件能力的综合训练,电路原理图+软件编程(C语言)。


课程学习内容~What?单片机编程包括哪些内容?

目录和大纲,归纳和总结能力训练



课程学习方法~How?如何学习单片机编程?

在掌握基础知识后,仿真与实验。

Linux平台:MCU 8051 IDE

Windows平台:uVision+Proteus

扩展提升:在学完51单片机后,能够快速自学更为通用主流的嵌入式系统,如下:

C51--(Arduino、MSP430)--(2812、28335)--(STM32、ARM9)--(TK1、BeagleBone、Raspberry Pi)

那么问题来了,我们为什么不直接学习STM32等,而是要学习51呢?

入门简单、上手容易,欲知详情点击查看。

  Blink
  Turns on an LED on for one second, then off for one second, repeatedly.

  Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO 
  it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
  the correct LED pin independent of which board is used.
  If you want to know what pin the on-board LED is connected to on your Arduino model, check
  the Technical Specs of your board  at https://www.arduino.cc/en/Main/Products
  
  This example code is in the public domain.

  Serial Call and Response in ASCII
 Language: Wiring/Arduino

 This program sends an ASCII A (byte of value 65) on startup
 and repeats that until it gets some data in.
 Then it waits for a byte in the serial port, and
 sends three ASCII-encoded, comma-separated sensor values,
 truncated by a linefeed and carriage return,
 whenever it gets a byte in.

 Thanks to Greg Shakar and Scott Fitzgerald for the improvements

  The circuit:
 * potentiometers attached to analog inputs 0 and 1
 * pushbutton attached to digital I/O 2
