LonWorks技术的核心芯片3120及3150都有11只I/O引脚,这些引脚可通过编程设定为各种不同的输入和输出功能,根据用户需要可灵活配置,使用起来十分方便.其有34种不同的I/O功能对象可供选择,这些功能又可分为输入、输出、双向三大类.根据输入输出的不同需要,利用软件定义某种I/O对象,然后利用芯片固件提供的对象界面对I/O对象进行编程,从而操作这些对象来完成特定的功能.
LonWorks core chips 3120 and 3150 have 11 I / O pins, these pins can be programmed for a variety of input and output functions, according to user needs can be flexibly configured, easy to use. 34 kinds of different I / O function objects are available, these functions can be divided into input, output, bi-directional three categories.According to the different needs of input and output, the use of software to define some I / O object, and then use the chip firmware to provide I / O objects are programmed through the object interface to manipulate these objects to accomplish specific functions.
