三菱电梯外呼小板研究（1）

本文转载自查看原文 2018-05-13 03:36 981 三菱电梯与单片机设计

对三菱外呼小板进行研究，通过示波器，逻辑分析仪，分析出三菱小板对应与液晶显示的逻辑，并通过实际现场实验得出

本来打算做远程监控的，觉得用此版麻烦，后来用can获取通讯，比这个简单。故丢弃不用了这些代码，

2017年4月份辛苦一个星期得来的，丢掉可惜。

清除资料之前，分享给大家，看的懂看看，看不懂的就算了，不提供技术支援，本来就是写的玩的。

禁止商业用途，只学习交流使用，本人不承担任何后果

以下是用STC15W4k芯片编写的，编写难免有些不足

函数接口说明

void GPIOxianshi(void);//初始化io口
bit tingyong(void);//只有显示停用显1，其他全部正常显0 ；
bit yichang(void);//只要不是自动，全变1
bit bianhua(void);//当显示有变化时，显1（包括停用）；做实时监控时使用

void ztsx_sxzt(void); //先状态，后上下；代码含义看程序直接两位代码
void Sendlouxian(void);//显示楼层直接显示楼层

点开+查看

#include "unstc15.h"
#include "uart.h"
#include "sl_xianshi.h"
#include "delay.h"
#include <intrins.h>
