Я пытаюсь сделать монитор ресурсов с помощью Arduino, и он прекрасно работает в течение почти 20 секунд, прежде чем он почти перестает работать. Когда он замедляется, между обновлениями уходит почти 5 секунд.
Я попытался закомментировать все с помощью psuti l и присвоить ему постоянное значение. и попробовал то же самое с GPUtil.
Вот код питона
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")
Вот код Arduino
