基于单片机的函数信号发生器的C语言代码，自己做的(Function signal generator based on single chip microcomputer C language code )

Simple Open Source EtherCAT Slave ==== SOES (Simple OpenSource EtherCAT Slave Stack) is an opensource slave stack that is very easy to use and provides a small footprint. It is a good alternative to more complex stacks on the market. Overview SOES is an EtherCAT slave stack written in c. Its purpose is to learn and to use. All users are invited to study the source to get an understanding how an EtherCAT slave functions. Features as of 1.0.0: - Address offset based HAL for easy ESC read/write access via any interface - Mailbox with data link layer - CoE - Object dictionary - SDO read and write for all sizes including segmented transfers - Easy portable C-code suited for embedded applications - Fixed PDO mapping - FoE with bootstrap template - Support for Little and Big endian targets. - Polling for interrupts

说明：  各位C51的爱好者能够看到我的拙作，这离不开龙 啸九天版主的支持，在此，我向他表示感谢，也相信C51BBS会越办越好！(C51 fan you can see my apology, which is inseparable from Long Xiao nine moderator support in this, I thanked him, and believe C51BBS will be better and better!)

基于ARM的俄罗斯方块设计，本次将设计实现一个用C语言编写的、在基于ARM核心的ADuC7020 ARM开发板上实现的单机版的俄罗斯方块小游戏。使用Keil3编程软件对C语言代码进行编写，支持按键操作，在实现过程中涉及了LCD液晶屏的图形显示、按键控制、LED控制、中断、蜂鸣器等嵌入式的编程技术。(Tetris ARM-based design, this will be designed to achieve a C language, the ADuC7020 ARM development board ARM core-based implementations of stand-alone version of the Tetris game. Use Keil3 programming software code written in the C language, support for key operations involved in the implementation process of the LCD screen graphical display, control buttons, LED control, interrupt, buzzer embedded programming techniques.)

此程序可实现长度为8位，周期为255的m序列，此序列可当做伪随机信号发生器，模拟信道噪声。(This procedure can achieve the length of 8 bits, the m sequence of 255 cycles, the sequence can be used as a pseudorandom signal generator, analog channel noise.)

关于瑞士SHT11程序，把采集的数据在液晶上显示(Switzerland SHT11 procedures on the data collected in the liquid crystal display)

基于51单片机的PT2314音频功放程序，可实现MIC和音频输入切换及音量音调控制，并用5110显示(Based on 51 single-chip audio amplifier PT2314 program can achieve MIC and audio input switching and volume tone control and display with 5110)

走马灯，包括原理图和源程序，功能齐全，运用单片机开发的代码(Lantern, including schematics and source, fully functional, use microcontroller development code)
