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.

Hi all

Well, I have tested by letting it run overnight, and on the average running 6 counters
from the same signal, it overruns by 11 or 12 counts, which is pretty good.
The hard part was finding an opto (amongst my bits) that would drive from 3.3 v
and had a low enough threshhold to pass a 0.8 vdc clock through.Settled for a OPI1264D.

Now that it runs the way it must,I have modified the code so there are less transmissions
to the PC. The concept being that there should'nt be any unsolicited transmissions,
a true Master Slave.

The only change to the logic, was to Zero the Timer, if and when all six were at -1.
Mainly because the transmissions become longer and longer, as the StartTime value
increases.

Gerard, I am very happy with the result, and it is mainly due to your BullDog like persistence. Many thanks once again.

Will run it for a few days now.

Regards

Hi Gerard,

On this last "industrial" version are also included those modifications from the "game" version (TOGGLE, VPOKE, etc.)? Can't test it this week...
Anyway, this version is the best and it may be the best candidate as a base for the next release!

Hi Vasi.

Yes, the firmware contains all the modifications I have been coding...

Hi all

Gerard, made one other small change.
Removed all +Chr$(13)

I was getting extra CR, with every print.
Probably MMBasic is the same as other Basics, and that is if you dont terminate a print
line with a ; then it will include a CR a LF or both.

So far so good.
