Efficient-BER-computation-of-LDPC-coded-SC_MRC-sy

红外解码数码管显示,用你一个外部中断和一个定时器中断来做的，虽然可以解码，但是效率不高，不建议在商用产品上使用。(IR decoding the digital tube display, you use an external interrupt and a timer interrupt to do, although it can be decoded, but efficiency is not high, not recommended for use in commercial products.)

这本C++程序设计书籍由清华大学郑莉所编写是目前C++程序入门的不错书籍。(This C++ programming books written by Tsinghua University Zheng Li is a good introductory book C++ program.)

名称：门禁模拟 模拟现实中门禁系统，可以输入密码进入也可以呼叫住户，再由住户按下开门按键 实现改密码功能，密码保存在24c02中能保证掉电不丢失密码。八个LED灯分别代表 8家住户，其中开门按键为共用，还带有忘记密码恢复按钮，模拟恢复出厂设置， 显示部分为LCD1602。程序共分为3种模式，分别为 等待输入 密码修改 呼叫住户 3种模式，其中等待输入是主要状态，所以在进入密码修改 呼叫住户模式后如果 长时间没有操作能自己切换到等待输入模式。(Name: Access Analog Simulating real access control system, you can also enter a password to enter the call households, again by pressing the open button households Implement change password function, the password stored in the 24c02 can guarantee non-volatile password. Eight LED lights represent 8 households, which opened the door keys are shared, but also with forgotten password recovery button, analog restore factory settings, Display part LCD1602. Program is divided into three modes, namely, waiting for a password to modify call households 3 modes, which is the main input wait state, so call households entering the password change mode if Their long time operation can be switched to the standby input mode.)

AD7705的采集12864显示，以及PCB电路，加工过了，可以使用(It is about the AD7705)

主要实现了STM32F10X的串口dma，实现了flash操作；并且 直接可以编译运行;(It mainly implements the serial port DMA of STM32F10X, realizes flash operation, and compiles and runs directly.)

硬件电路比较简单，3个LED指示灯，5个按键控制上下左右及暂停，LCD显示。总共有20关。设计用到了逻辑门控制电路。(The hardware circuit is simple, 3 LED lights, 5 key control above and below and suspension, LCD display. A total of 20 customs. The design used in the logic gate control circuit. )

Himax LCD Initialization code

esp8266测试源码,测试STA和AP功能。并且对TCP,UDP测试（来自原子）。(Esp8266 test source code, testing STA and AP functions. And for TCP, UDP tests ( atoms).)

说明：  第一代扫地机器人自由避障程序，采用八路红外传感系统外加中路超声波测距传感进行自由避障，外加死角自动回避程序(The first generation of sweeping robot free obstacle avoidance program, using eight infrared sensor system plus middle ultrasonic distance sensor to free obstacle avoidance, plus dead angle automatic avoidance program)

可显示六方晶系的0001标准极图，可改变c/a比，可根据输入显示极点。(Shows the six-crystal pole figure of the 0001 standards, can change the c/a ratio, based on input display pole.)
