Hi Christophe and Matthias --
The "TimeLab" mode code was broken with the seemingly-minor change in
the 2020 version of allowing varyiable numbers of decimal places in the
results (with the default of 11) I had to rework the TimeLab mode code
and I screwed it up.
I spent some time on this last week and have implemented a hopefully
much simpler and cleaner routine that will work properly.
Unfortunately, I had to go out of town and won't be able to test the
changes until I get back later next week. I'll post a note to the list
when I've done that and a new binary version is available.
Sorry for the regression.
John

Hi John, hi Matthias
I have the same problem with the channel C output of the TICC with the
latest firmware.
John, we already had direct email contact therefore from the end of April
to early May 2020. I had already tested all available versions in
conjunction with Timelab. Here are the data with version 2017, which in my
opinion works hard-free, but without the improvements in recent versions.

Did other time-nuts have found this problem and possibly a solution?
It would be great if John would process the problem again.
Many Thanks
Best regards,
Christoph

Hi Matthias --
I just took a look at the source and the "Debug" is meaningless...
stupid program error (missing a "break" in a case statement) caused that
to be printed when it shouldn't be. Easy fix.
But why you're seeing the bogus chC results will take a little more
investigation. I suspect it's something that broke when I made changes
to the print routine in the latest version. I'll see if I can figure it
out, and if/when I do I'll push changes to the github repository.
Thanks for letting me know about the problems!

Hello Time-Nuts,
after I finally managed to get my TAPR TIC into a case,
together with two 1PPS dividers, I wanted to give the 3
channel measurement a try. I remember that I successfully
used the TimeLab mode some years ago, but this time I can´t
get it to work. I installed the lasted firmware (binary from
github).
Channel A and B work fine, but the (B-A) doens´t seem to be
calculated - see output from TIC below.
Should the line reading "debug" in the TIC Configuration
make me nervous?
Any help highly appreciated...
Thanks & have a nice weekend,
Matthias
