本文主要是介绍智能家居6 -- 配置 ini文件优化设备添加，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
不知道什么是ini的朋友可以先看这篇:一文带你入门ini格式-CSDN博客
准备
如下图:
在src 下面添加 ini.c
在inc 下面添加 ini.h
在 receive_interface.c 里面包含头文件，把之前添加的设备类注释掉
这时候就可以把相关设备的(.c .h)文件给删掉了
如下图:
修改/添加 代码
gdevice.ini
[lock]
key=0x44
gpio_pin=8
gpio_mode=OUTPUT
gpio_status=HIGH
check_face_status=1
voice_set_status=1[beep]
key=0x45
gpio_pin=9
gpio_mode=OUTPUT
gpio_status=HIGH
check_face_status=0
voice_set_status=1[BR led]
key=0x42
gpio_pin=5
gpio_mode=OUTPUT
gpio_status=HIGH
check_face_status=0
voice_set_status=0[LV led]
key=0x41
gpio_pin=2
gpio_mode=OUTPUT
gpio_status=HIGH
check_face_status=0
voice_set_status=0[fan]
key=0x43
gpio_pin=7
gpio_mode=OUTPUT
gpio_status=HIGH
check_face_status=0
voice_set_status=0修改init
我们需要把gdevice.ini 文件传送到arm 设备的 /etc/下面
sudo cp gdevice.ini /etc/
修改后的receive_interface.c

};
这样要是我们需要对设备进行维护:
比如添加某个新的设备只需要去 gdevice.ini 里面去添加即可 -->方便维护
这篇关于智能家居6 -- 配置 ini文件优化设备添加的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
