使用RPi Pico和Python升级旧酷派笔记本电脑

#1

我有一台10年前买的旧笔记本电脑酷派。除了添加RGB灯外，我还心想，如果笔记本电脑能自动控制散热板，那该有多好。因此，我经历了以下步骤。我使用了Python中的psutil和gputil库来提取笔记本电脑的硬件信息，您可以看到下面的Python脚本。

代码：全选

import psutil
import GPUtil as gu

def show_gpu_temp():   
        
    gpu = gu.getGPUs()[0]
    return gpu.temperature


def show_cpu_freq():

    current_freq, _, _ = psutil.cpu_freq()
    return current_freq

def show_cpu_perecent():
    
    cpu_perecent = psutil.cpu_percent()
    return cpu_perecent

def cpu_core_count():
    cpu_cores = psutil.cpu_count()
    return cpu_cores

def show_memory_info():
    total_memory, available_memory, percent, used_memory, free_memory = psutil.virtual_memory()
    return percent

在获得笔记本电脑硬件信息后，我们将这些信息发送到我在LabVIEW图形环境中以框图的形式编写的程序中。LabVIEW的图形面板以一种吸引人的方式显示信息。在收到信息并以图形方式显示后，我通过蓝牙通信向Raspberry Pi Pico微控制器发送控制命令以打开酷派风扇。当向Raspberry Pi Pico发送开机命令时，RGB指示灯也会亮起。您可以在下面看到以框图形式编写的程序。

最后，在我用Microython语言编写的脚本的帮助下，我通过蓝牙通信接收控制命令。一旦Raspberry Pi Pico收到命令，它就可以启用或禁用冷却板风扇和RGB环。你可以看到我为Raspberrry Pi Pico编写的程序以及下面的电路图。我还使用了L298电机驱动程序来运行冷却板风扇。我还使用了HC-05模块进行蓝牙通信。
