PIC的单片机大部分都会有I2C接口,但它的少脚的型号就没有,这是要接I2C接口的器件就只能用软件模拟的I2C协议来驱动了.这里提供了一个用汇编语言写的AT24C02的程序.里面是通过两个灯来指示写的数据和读的数据是否一致.-Most will have a PIC microcontroller I2C interface, but it is no less foot model, which is the interface to access I2C devices can only be simulated by software to drive the I2C protocol. This provides a written in assembly language AT24C02 procedures. which is written by two lights to indicate the data and read data are the same.
