serial write a command and print output to file
I am new to serial programming in Python. Basically, doing the same command I would do in Putty or some other terminal. Get output from Putty after running command "dz 0x80000000 4096" to a TiVa processor but not with Python3.6.5 program I wrote below. Get no output as if it didn't write the command. Also didn’t print output to screen after running the write command.
Program below:
import logging
import serial
import serial.threaded
import threading
import time
timeout = time.time() + 15 #may have to adjust, 10 seconds from now
import sys
import csv
from datetime import datetime
ser= serial.Serial('COM19', baudrate = 115200,parity=serial.PARITY_NONE,
stopbits=serial.STOPBITS_ONE,bytesize=serial.EIGHTBITS,rtscts=True,timeout=2,writeTimeout=5)
def getvalues():
ser.write(b'dz 0x80000000 4096') #printed 18, not sure if it ran the command?
IQ_data = ser.readline().decode('ascii')
return IQ_data
while(1):
with open("E:/HigherGround_Home/Pyserial_Gurb/log.txt","w") as f:
writer = csv.writer(f)
writer.writerow(getvalues())
if time.time() > timeout:
break
f.close()
Can someone please help me get my program to correctly print to a file?
Thanks,
