Hi Carsten,
Thanks again. I tried the first four things and here is what I got:
1.) tc@piCoreLMS:~$ sudo modprobe i2c-dev YES, NOTHING SEEN.
2.) tc@piCoreLMS:~$ sudo python3 /home/tc/argononed.py
File "/home/tc/argononed.py", line 102
while True:
^
IndentationError: unexpected indent
3.) tc@piCoreLMS:~$ ^C NOTHING HAPPENED.
4.) tc@piCoreLMS:~$ sudo vcgencmd measure_temp THIS SEEMS FINE.
temp=36.5'C
5.) Then, I typed in cat argonone.py and see this:
tc@piCoreLMS:~$ cat argononed.py

tc@piCoreLMS:~$
I tried to type in "||" (two vertical bars), but it didn't accept this
command. Maybe it's not supposed to be vertical bars???
tc@piCoreLMS:~$ ||
-sh: syntax error: unexpected "||"
Finally, to check and see if I could change the fan settings, I typed in
"fanconfig", but this is what came back. What am I doing wrong?
tc@piCoreLMS:~$ fanconfig
-sh: fanconfig: not found
So, maybe it looks like things are more o.k. than I thought??
Cheers
