基于I^2C总线的门禁控制器设计

Design of Door-Safeguard Controller Based on I^2C Bus

介绍了I2C总线及其外围器件的特点,设计了基于I2C总线的门禁控制器。该控制器利用P87LPC76X系列单片机,通过I2C总线与外围芯片相连,具有使用灵活、控制方便等特点。给出了部分硬件设计和软件流程。

The characteristics of I2C bus and its peripheral devices are introduced, and a door-safeguard controller based on I2C bus is designed with the MCU of P87LPC76X, which connects the host through I2C bus. It has many advantages such as agility and easily being controlled. Moreover, the design of hardware and the flow of software are presented in this paper.
