Question

我正在尝试使用arduino进行资源监控，并且它在几乎停止运行之前已经运行了将近20秒。当速度变慢时，两次更新之间大约需要5秒钟。

我尝试用psuti l注释掉所有内容，并赋予它永久性的价值。并尝试过使用GPUtil。

这是python代码

import serial.tools.list_ports
import serial
import psutil
import GPUtil
import time
import serial

ports = list(serial.tools.list_ports.comports())
baud = 9600
for p in ports:
    if "Arduino" in p[1]:
        port = p[0]

ser=serial.Serial(port, baud, timeout=1)
try:
    while True:
        cpuUsage = psutil.cpu_percent()
        ramUsage = psutil.virtual_memory()
        cpuUsage = str(cpuUsage)


        GPUs = GPUtil.getGPUs()
        gpuUsage = GPUs[0].load
        gpuUsage = str(gpuUsage)
        gpuUsage = gpuUsage[2:]

        ramUsage = str(ramUsage.percent)

        toSend = cpuUsage + "," + gpuUsage + ","+ ramUsage
        print (toSend)


        ser.write(toSend.encode())
        #print("20.5".encode())




        #line = ser.readline()[:-2]
        #line.decode()
        #print ("Read : " , line);
        time.sleep(0.1)
except:
    print ("error")

这是Arduino代码

现在已修复，不确定它是什么修复程序，但它至少可以工作:) 比一切企图停止的要好

python脚本变慢，几秒钟后几乎停止
