485MODBUS

在Linux操作系统和ARM嵌入式实验系统环境下，分析linux下的键盘、LED驱动程序，编写一个应用程序，实现以下功能：在ARM开发板上按下数字键1、2、3时，对应启动模拟量AIN0、AIN1、AIN2采样，并把AD转换的结果从终端输出和LED显示。(Environment of the Linux operating system and ARM embedded experiment system, the Linux keyboard, LED driver, write an application, the following functions: ARM development board to press the number keys 1, 2, 3, corresponding to the start the analog AIN0, AIN1, AIN2 sampling and AD conversion results from the terminal output and LED display.)

一个多通道ADC转换DMA传输数据。程序是选择的通道0和通道1，各采集50次，然后滤波取其平均值，并发送到串口显示采样的电压值。(A multi-channel ADC conversion DMA transfer data. Program is selected channels 0 and 1, each collecting 50 times, then filtering the mean value, and sent to the serial display sampled voltage value.)

桌面监视器,带键盘监视功能 可用于关闭一些广告窗口或不希望出现的任意窗口,键盘监视功能带回放器,可播放鼠标键盘的操作过程(desktop monitor, with the keyboard function can be used to monitor the closure of some advertising window or do not want to see is the arbitrary window, Keyboard surveillance function with playback device that can broadcast mouse keyboard operation process)

COG12864,ST7567测试程序，8080并口协议(COG128*64DOTS,Test code for st7567,and the interface is 8080 parallel)

说明：  基于51单片机的按键例程，常见问题： 1. 按键无反应 请您确认程序是否下载成功，连线正确无误，确认无误后还是无效果的话，将排线重新插拔下，单片机拿下来重新安装，重启开发板试试！(Key routines based on 51 single chip microcomputer,common problems: 1. Press the key and no response. Please confirm whether the program was downloaded successfully and the connection is correct. If it is still ineffective after confirmation, plug and unplug the cable again, take down the MCU and reinstall it. Restart the development board to try!)

驱动IC-LG4524的驱动程序。该程序能点亮TFT2。2的LCM(Driver IC-LG4524 driver. The program can be lit TFT2. 2 of the LCM)

本程序采用C语言编程，利用proteus仿真实现定时器功能。(This program uses the C programming with proteus simulation clock function )

基于430的AD9954驱动程序，单频，FSK等全有。(430 AD9954 driver, single-frequency, FSK, such as whole.)

stm32产生spwm程序，利用TIM1和DMA，通过PA8和PB13输出spwm波(stm32 produce spwm program, using TIM1 and DMA, and PB13 through PA8 spwm wave output)

自动寻找指定WIFI ssid并填入密码，自动打开wifi连上网。(Automatically find WIFI specified ssid and fill in the password, automatically open WIFI even surf the Internet.)
