利用电脑上的并口中的第2、3、10脚模拟I2C总线协议通讯，从而利用电脑作为上位机，通过并口模拟I2C协议控制、访问和管理各种支持I2C协议的芯片，如DS1856等，ReadData从芯片读数据，WriteData写数据到芯片，其他文件为子程序，并口上第2脚为SCL，第3脚为SDA，第10脚为芯片上报SDA状态脚-And the first use of simulation I2C bus protocol 2,3,10 foot mouth communication on a computer, so the use of computers as a PC through parallel simulation I2C protocol control, access and manage a variety of support I2C protocol chip, such as the DS1856, etc., ReadData read data from the chip, WriteData write data to the chip, other documents as subroutines, parallel to the first two legs SCL, 3 feet of SDA, the first 10 feet of the chip status reporting SDA pin
