该软件包只用在100K或400K速度的I2C器件，如果用在低速一些的器件（如：ZLG7290）就需要调整运行时间,如在通信过程中增加NOP指令等增加延时时间.-The package is only used in the 100K or 400K speed I2C devices, if used in a number of low-speed devices (such as: ZLG7290) on the need to adjust the running time, such as an increase in the communication process and so increase the delay time of NOP instructions.
