先上一些参考资料,主要来源知乎:
1 -怎样学会单片机?-
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?

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
