想起刚刚入手树莓派4B、配置开发板初始环境(Raspberry pi os)的时候,在raspi-config工具中遇到的一个风扇控制功能: 在命令行中输入:sudo raspi-config,随即进入了一个模拟图形配置界面 选择Performance Options->Fan->Enable fan temperature control->Pin->Temperature raspi-config工具主界面 选择设置GPIO风扇行为 开...
rpi-cpu-fan:Raspberry Pi自动CPU风扇控制Su**us 上传76KB 文件格式 zip Shell Raspberry Pi自动CPU风扇控制 动态睡眠间隔 CPU温度离阈值越远,脚本Hibernate的时间就越长。 X轴是温度,Y轴是睡眠时间。 随着温度的升高,从左到右,睡眠时间(绿线)以Y = -X/2的斜率稳定缩短。 一旦温度达到ON阈值(蓝色垂直线),...

Raspberry Pi 40 引脚 GPIO 接头 风扇连接器 实时时钟 (RTC) RTC 电池连接器 电源按钮 一、关机后再开机 首次将 Raspberry Pi 插入电源时,它会自动打开并启动操作系统,无需按下按钮。 如果你运行的是 Raspberry Pi Desktop,你可以通过短按电源按钮来启动干净利落的关机。这时会出现一个菜单,询问你是要关机、重启...
Inside was a mains power cable, 15V DC power brick, two HDMI jumpers, a USB jumper, accelerometer shim, SD card ribbon, small 5V fan, heatsinks for the Pi, screwdriver and mounting screws, a manual and the RasPad LCD screen itself. ...
However, I am not sure if this is actually feasible, and even if this challenge were beatable, that there is enough will and time on Pi's engineers side to solve this. EDIT: I wonder if connecting the fan to 5V&GND GPIO while keeping the PWM pin in the fan header would work around...
