我正在尝试从设备收集串行数据,时间戳并将其导出到.csv文件。
以下程序将日期和时间写入csv,但不写入从设备模块返回的数据:
import time
import csv
import fio2
def Csv_creator():
my_file = open('test_csv.csv', 'w+')
with my_file:
new_file = csv.writer(my_file)
def Timestamp():
date_now = time.strftime('%d/%m/%y')
time_now = time.strftime('%H:%M:%S')
return [date_now,time_now]
def Write_loop():
Csv_creator()
fio2.Initialize()
with open('test_csv.csv', 'a') as f:
csv_file = csv.writer(f)
for num in range(0,20):
[date_now,time_now] = Timestamp()
fio2_data = fio2.Reader()
print(fio2_data)
csv_file.writerow([date_now,time_now,fio2_data])
Write_loop()
设备模块如下所示。它返回数据,我可以打印它。唯一的问题是无法将其写入csv文件。
import serial
ser = serial.Serial("COM4",
baudrate=2400,
bytesize=serial.EIGHTBITS,
parity =serial.PARITY_ODD)
def Initialize():
global ser
try:
ser.isOpen()
print("\n Serial is open")
except:
print ("Error: serial Not Open")
def Reader():
global ser
if (ser.isOpen()):
try:
x = ser.readline().decode()
x = (x)
return x
except:
return "unable to print"
else:
return "cannot open serial port"
答案 0 :(得分:0)
我明白了。我不得不删除一些与小数值相关的垃圾信件。首先,我将收到的数据更改为字符串并替换垃圾字母。以下是我改变它的方式:
[date_now,time_now] = Timestamp()
fio2_data = str(fio2.Reader()).replace("\r\n","")
fio2_data = fio2_data.replace("\x000","")
write_list = [date_now,time_now,fio2_data]
