AD7705驱动程序，通过51实现，希望有用。(AD7705 driver, 51 achieved by the hope that useful.)

stm32主控芯片实现对T5557卡的读写，资料包括读卡电路，T5557卡片的相关技术文档，上位机及工程源码。(The main control chip of STM32 realizes the reading and writing of T5557 card, including the reading circuit, the related technical documents of T5557 card, the host computer and the engineering source code.)

说明：  ADC0832是一款串行数据的AD转换芯片，该代码完成ADC0832的初始化以及应用。(ADC0832 is a serial data of the AD converter chip, the code completion of the initialization and the application of ADC0832.)

一个简单的串口示波器，使用的时候请首先安装labview 的visa驱动 此文件为labview2014创建，请使用不低于labview2014的版本打开使用。(a simple OSC using serial port)

c8051f的tcpip源程序,新一代功能比较齐全的c8051f020单片机的串行通信c程序,通用的c8051系列tcpip源程序，同时包括了ucos的移植。 (c8051f the tcpip source, a new generation of relatively complete functional C8051F020 MCU serial communication c procedures, C8051 Series tcpip common source, at the same time includes uCOS transplant.)

单片机C语言程序设计实训100例——基于8051+Proteus仿真(Microcontroller C Programming Language Training 100 cases- based 8051+Proteus simulation)

说明：  STC15W4K56S4 4串口均已初始化，可正常使用。(STC15W4K56S4 four uarts.)

说明：  DS18B20多IO驱动，带有滤波，数据更稳定精确(DS18B20 driver, with filtering, more stable and accurate data)
