stm8s 1-wire lybrary

采用信息钮（ibutton）与单片机设计实现了门禁系统，研究了1-wire协议，采用C语言完成ibutton序列码的读取-Using information button (ibutton) and microcontroller design to achieve the access control system, 1-wire protocol, using C language to complete the the ibutton sequence code reader

A microprocessor can easily generate 1-Wire timing signals if a dedicated bus master is not present. This application note provides an example, written in C , of the basic standard speed 1-Wire master communication routines that are used for iButton
