ATMEGA128 各种实用程序，C代码，初学者实用(ATMEGA128 various utilities, C code, beginners practica)

使用单片机任意IO口用软件的方法模拟实现异步串行数据传输的方法，并采用多次采样软件方法来增加软件模拟串口通讯的可靠性，在以上基础上，进一步用具有中断功能的IO口来实现数据的接收，从而增加软件模拟方式的实用性和灵活性；(The use of single-chip arbitrary IO port with the method of software simulation method to realize asynchronous serial data transmission, and the reliability of software sampling method to increase the software simulation of serial communication, on the basis of the above, further with interrupt function of IO port to realize the data receiving, thereby increasing the practicability and flexibility of software simulation method;)

基于STM32F407实现俄罗斯方块基本功能(Based on STM32F407 realizes Russia square basic function)

说明：  PC通过串口控制Zigbee温度传感器的采集启动与停止。。。(PC controls the start and stop of Zigbee temperature sensor acquisition through serial port.)

12864驱动程序（51串行）已通过检测，用时注意端口的定义(12864 Driver (51 serial))

三星94c8芯片写的线控器显示屏，TM1640，模拟串口(Samsung 94 written c8 chip line controller display, TM1640, simulate the serial port)

说明：  sd卡初始，由于SD卡使用SPI模式，并且是块读取(512Byte),所以需要单片机提供大于512的可用RAM，以供缓冲使用 这里可以选择STC89c52RD+、STC89C58RD+、STC89C516RD+，后缀RD+表明扩展RAM是1024字节，RC表明扩展RAM256字节(sd card original, because the SD card using SPI mode, and is a block read (512Byte), so they need the microcontroller to provide more than 512 of the available RAM, for buffer used here can choose STC89c52RD+, STC89C58RD+, STC89C516RD+, the suffix RD+ that extended RAM is 1024 bytes, RC that extended RAM256 byte)

stc系列单片机系统与1602液晶静态显示程序(1602 static display program)

说明：  基于STM32的电子墨水屏驱动程序,C语言。(eink driver for STM32)
