DoubledImplement2

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.)

说明：  基于固件库的STM32F103 ADC采样例程(STM32F103 ADC demo,just for learning)

使用C8051F020驱动的DAC8541程序，其他单片机也可以参考。(DAC8541 use C8051F020-driven program can also refer to other microcontrollers.)

本节所给出主程序功能为51单片机从USB总线读取两个字节数据，计算两个数据的和。另外本文还给出了CH372的主端点、辅助端点之间数据上传下传的子程序，供读者参考。(The main function of this section is given as 51 microcontroller reads the two bytes of data the USB bus, two data and computing. This article also gives additional primary endpoint between the auxiliary endpoints CH372 Uploaded data transfer routines, for reference)

nxp 的lpc1788中文手册，很详细的介绍了LCD等模块作用，适合开发gui用(nxp of lpc1788 Chinese manual, very detailed introduction to the role of LCD module, suitable for the development of gui use)

74HC595移位测试程序，带PRITUES仿真，以及2个74HC595串联(The the 74HC595 shift test program with PRITUES simulation, as well as two 74HC595 in series)

基于stm32对ads1298进行读取，用于心电前端采集(Based on ads1298 stm32 read, front-end for ECG acquisition)

说明：  基于msp430单片机的液晶12864的驱动程序简单。。(The driver of LCD 12864 based on MSp430 MCU is simple.)

基于020的简易信号分析仪，能够实现40khz以下的方波、三角波、正弦波频率、幅值检测及频谱分析。(Signal-Analysis system based on 020. Measuring magnitude, frequency of square,triangle,and sin signal under 40khz,including frequency spectrum analysis. )

基于S3C44B0芯片,在显示屏上显示字体的源程序(S3C44B0 based chips, on the screen shows the source fonts)
