Here is the Python 2.7.16 code I quickly put together to send unix time to the Arduino UNO.
I assume it also works on Python3, but I have not tested it because I have not completely upgrade python on my mac pro yet, sorry about that.
Code:
# -----------------------------------------------------------
# Sync Unix Time with Arduino Initial Draft 0.1
# Written on macOS, tested with Python 2.7.16
# Neo, December 2019
# This code needs refinement to be more general
# I will improve this code later when I need to use it in an Arduino project
# For now, it works "OK" and serves it purpose
# Feel free to improve, modify as you like.
# -----------------------------------------------------------
import serial
import time
ser = serial.Serial(
port='/dev/cu.usbserial-40', #change this for your device
baudrate=9600,
parity=serial.PARITY_NONE,
stopbits=serial.STOPBITS_ONE,
bytesize=serial.EIGHTBITS,
timeout=0)
print("connected to: " + ser.portstr)
# this will store the line
line = []
ux = 0
a = False
debugScript = False
offset = 2 . #adjust this time offset (in seconds) to account for various time delays in script and transferring via the serial port, etc. to insure the Arduino is in closer sync to the computer
time_int = 1000 # this can be any number greater than zero and less than recent unix time
count = 0
while True:
if debugScript:
print(str(int(time.time())))
for c in ser.read():
if not a:
if ux < time_int:
ser.write("T")
ux = int(time.time())+offset
ser.write(str(ux))
ser.write("\n")
ser.flush()
if debugScript:
print("unixtime: " + str(ux))
line.append(c)
count += 1
if c == '\n':
print("Line("+str(count)+"): " + ''.join(line))
x = int(time.time())+offset
print("time("+str(count)+"): " + str(x) + "\n")
line = []
a = True
break
ser.close()
I am assigned a programming work.It is my first time to use unix.
The task is writing a shell script to interrogate the university Unix operating system to determine the number of "Runnable" processes at any given time.Then append the result,along with a time-stamp,on a log file. Also there are... (1 Reply)
I have a list of interfaces and time the interface was last active. I can't figure out how to convert the time in the second column,

Here is two time I have:
Jul 12 16:02:01
Jul 13 01:02:01
and how can I do a simple match to get difference between two time which is 09:00:00
Thanks in advance. (3 Replies)
I'd like to convert a date string in the form of sun aug 19 09:03:10 EDT 2012, to unixtime timestamp using awk.
I tried
This is how each line of the file looks like, different date and time in this format

I needed some help in adding a duration (in seconds) to a start time (in hhmmss format) and a start date (in mmddyy format) in order to get an end date and end time. The concept of a leap year is also to be considered while incrementing the day. The code/ function that I have formed so far is as... (3 Replies)
Hi guys thanks for the help for my previous posts.Now i have a requirement that i download a XMl file which has UTC time stamp.I need to convert UTC time into Unix server timezone.
For ex if the time zone of unix server is CDT then i need to convert into CDT.whatever may be the system time... (5 Replies)
In my further exploration of Arduino, today I decided to install the arduino-cli on my mac today.

I followed the instructions for macOS but when I got to this part:

I got the dreaded "Unknown" Fully Qualified Board Name... (1 Reply)

ser.cfg - ser configuration file
SYNOPSIS
/etc/sfw/ser/ser.cfg
DESCRIPTION
ser reads the configuration data from /etc/sfw/ser/ser.cfg (or the file specified with -f on the command line). The file contains global
configuration parameters, module loading commands and the script that will be executed for each received request. Lines starting with # or
enclosed in /* ... */ are interpreted as comments.
