RX-8025T时钟芯片应用手册-EPSON

说明：  基于c8051f340的AD转换后数据由串口UART输出(AD converted by the serial UART data output)

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.)

用PWM脉宽来控制单片机上LED灯的亮度(Using PWM to control the brightness of LED lamp on single chip microcomputer)

PIC16F877单片机硬件IIC编程(PIC16F877 microcontroller programming hardware IIC)

本设计采用AT89S51单片机，设计电子钟，并用数码管显示！(This design uses the AT89S51 microcontroller design electronic clock with digital display! )

熟悉keil仿真软件、proteus仿真软件的使用。了解并熟悉单片机I/O口和LED灯的电路结构，学会构建简单的流水灯电路。掌握C51中单片机I/O口的编程方法和使用I/O口进行输入输出的注意事项。(Familiar with the keil simulation software, proteus simulation software use. MCU I/O port and the circuit structure of the LED lights, and become familiar with how to build a simple water lamp circuit. Grasp the C51 MCU I/O port programming and I/O port input and output of Note.)

里面含有一些STC12系列单片机常用的硬件驱动程序和片上资源驱动程序。工作在11.0592MHZ可以直接使用。如12864的串口方式驱动，1602驱动，18B20驱动，DHT11驱动，STC片上EEPROM/ADC/PWM等驱动程序，还包括一些经过本人用示波器侧过的STC12系列单片机在11.0592MHZ下的软件延时子函数。这些东西对你平时开发会大有帮助。(failed to translate)

说明：  avr单片机学习程序，可供新手学习基础编程(avr single-chip learning process for novice programmers to learn the basis of)

采用NXP出品的高集成度PN532读写芯片， 符合ISO/IEC18092（NFC）标准，兼容ISO14443（Type A、Type B）标准。采用USB接口与电脑进行通讯及供电，不但可以读取符合Mifare标准的Classics（M1、M4、MUL）和DESFire卡，还支持FeliCa卡等符合NFC规范的非接触式IC卡。(IC card and entrance guard card reading and writing)
