I used a 4DSystems 4Dcapes for the BBB (
https://4dsystems.com.au/products/primary-display-modules-capes-shields/4dcape-70t)
and added a real-ttime clock board and an analog I-O board that I designed
and had fabbed at OSH Park. I used Debian Linux OS and programmed it in
Python along with
that worked well. It would be nice to have such a tool for the BBBs.

I'm trying to disable the service that gets the time and date over the
Internet. I want to do that in hopes that the BBB will instead get the time
and date from my Adafruit DS3231 and I suspect the BBB is trying for a
minute to get the time and date over the Internet. with the result that the

Thanks Micka.
I just now tried that and putty.exe said that ntp isn't installed, so
not removed, but I'll bet it's gotta be something like that. Maybe
something for the Internet connection.

What script is trying to read the clock data from ntp? I have an Adafruit

I mounted the Adafruit DS3231 RTC module on a breadboard and using the

The only down side is that if your program crashes, you have to wait
up to a minute for the crontab to run the check_processes.bash, but
otherwise is pretty solid.
Now I am also looking for how to run my script as a system service.

I couldn't make any sense of the Debian bone79, just seeing the blank

Eh ? What do you mean ? You do realize that you can create a tmpfs
directory, that is located in memory, where you could then create
files that are also placed in memory ?

My program runs fine but requires that I use putty.exe and type sudo python
myprog.py to run it. I have been reading about systemctl and have written a
service file and put it in /lib/systemd/system. It's called
paint-flow.service, listing below. I have.. enabled it with systemctl
enable
Now after all that I've decided not to write anything to the eMMC, fearing
that I'll cause some hiccup with the writes.

Gosh, how did I miss that, that the mode is a string. Well it had to be
something simple like that. Quoting the w and r fixed the problem. Very
embarrassing.

I want to store a little data on the eMMC from my Python code. My program
is not getting errors when I try to write a very short data file but it
doesn't actually seem to write it as I cannot read it back. I am using
f = open('MyFile.txt', w)
or
f = open('/home/debian/Desktop/MyFile.txt', w)
