模拟I2C主机的比较多，模拟I2C从机的资源不多，从机相对主机而言要难一些，这个供大家借鉴。 这个从机程序支持主机对它的随机写和随机读，连续读和连续写没做。(Simulation I2C host more, simulation I2C slave modest resources, from the host machine is relatively more difficult in terms of some of this for your reference. The host from the machine it supports random write and random read, sequential read and sequential write did not do.)

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.)

STM32_PLC_CODE，在STM32平台上直接移植，能实现基本的PLC功能指令，仅限学习之用。(STM32_PLC_CODE, transplanted directly on the STM32 platform, to achieve basic PLC functions instruction, limited to learning to use.)

1302时钟芯片，1602液晶显示年月日，并且时间可调(1302 clock chip, the 1602 LCD date and time adjustable)

说明：  双路输出控制器”具有信号输出时间设定、 输出信号占空比调整、 当前输出通道及时 间显示、系统工作参数存储、串口通讯及 LED 指示等功能。 “双路输出控制器”通过串口完 成信号输出时间设定功能；通过 EEPROM 完成系统工作参数存储功能；通过按键完成输出通 道切换、 输出信号占空比调整及停止信号输出功能； 系统硬件电路主要由 MCU 控制单元、独 立按键、 LCD 显示单元、 串口通讯单元、 EEPROM 数据存储单元和 LED 指示单元组成(Dual output controller has the signal output time setting, adjust the duty cycle of the output signal, the current output channel in time Between display, system operating parameters are stored, serial communications and LED indicator. Dual Output Controller through serial END A signal output time setting function complete system operating parameters via EEPROM memory function complete output pass through the key Channel switching, adjust the duty cycle of the output signal and the stop signal output function the system hardware circuit is mainly controlled by the MCU unit, alone Li buttons, LCD display unit, serial communication unit, EEPROM data storage unit and LED indication units)
