Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

3 years ago I presented MMTimeLord as an aid to calibrating micromites.




I have added a few more options to allow it to be used for calibrating Armite RTCs as well as testing all the other devices we now have.
Back in Jan 2016, we discovered that FTDI USB adapters didn't have consistent timing. They still don't and nor does the microbridge. The timing can be up to 15mS out at any given time.
CH340 adapters are good and so are the Armite NUCLEU devices.

The ZIP contains a manual and sample spreadsheet.


The frequency fluctuations on the micromite are obvious here. First, a finger on the chip to heat it up then zapped with some freeze spray.

Hi Jim
I doubt this but is there any way to run this using SSH rather than the serial port?

It looks to be a Windows (perhaps DOS) EXE so not really ideal for that.

I meant can the program be run from Windows with the Pi connected by Wifi rather than serial port

Networks are unreliable as far as consistent speed goes, especially WiFi.
I have thought about adding Telnet to it and will give it a try sometime.

As far as SSH goes. Not likely.
The only way I can use SSH is through Putty's Plink and that is not for the faint-hearted.

I don't have the ability/desire to code my own SSH links.
