打开/boot/config.txt 在最后一行手动添加这个:dtoverlay=w1-gpio-pullup,gpiopin=4 supperllx 初级粉丝 1 然后你加载模块后就可以把w1设备接在pin7了 sunharrison 人气楷模 12 @supperllx 试试这个 我建了一个test.py手动了几次 python3 test.py就有报错了#!/usr/bin/env python3import osimport time...
w1-gpio-cl This is a Linux kernel-mode driver, intended as an enhancement/substitution of the standard Linux w1-gpio 1-wire bus master driver. Contrary to the standard driver, w1-gpio-cl is not a platform device driver, therefore doesn't need any specific device-tree overlay nor preconfigur...
树莓派的单线数据接口是只需要一根线就能通讯的总线,通常用来与某些传感器通讯。 树莓派支持在任何引脚上启用单线数据接口,但默认使用 GPIO 4。 要启用单线数据接口,你需要编辑/boot/config.txt并添加以下信息,然后重启树莓派: dtoverlay=w1-gpio 或者,如果你想用除了 GPIO 4 以外的其他引脚: dtoverlay=w1-gpio,gpio...

I switched volatage to 5V and all good, but I wondering is it possible to initialize w1 bus on another GPIO? After I google that and so some reading, people achieve that on raspberry but they patched the kernel somehow. Any idea how can that be done on armbian? Thomas Pfeiffer Members...

分析及建议: 建议一般至少3小时喂一次的,不能隔的时间太长了,大便是正常的,因为早产儿后期需要追赶性生长,2小时柔柔脚丫把她弄醒,也不是慢,主要要跟出生体重比较的,3个月时体重达出生体重2倍就是正常,建议早产儿奶粉,不需要的,这是乳牙,母乳不够尽早添加奶粉,不需要特殊处理的,你的宝宝需要定期到儿保科体检的...
