Pause duration dependence on CPU speed...

Hi,
I finally got around last night to fixing up the port of my setup from an 8811 extended to the 8910 v1.1 extender. My macros seemed to be way off, not executing all the commands. I finally sorted it out after re-reading the Pause special protocol documentation. It mentions that the pause duration ($FF being the longest) depends on the CPU speed. In one of my startup macros in the 8811, I use a single pause of $10. What duplicated that duration in the 8910 ext 1.1, was on the order of 10 $FF's!

Is the 8910 that much faster than my good 'ole 8811?

Doesn't matter to much except that I ran into the number of macro command limitations that I had to work around. the 8910 is blazing fast under the extender.

Best,
jeff

The 8910 extender's built-in Pause protocol has a known history of being somewhat ... short. I suggest you delete the built-in Pause Protocol upgrade and replace with the one from KM or RM. You will then see more useful Pause durations.

Thanks Capn.

Did it and it works much better....

Thanks again,
jeff

Pause in few extenders I looked at is done by the LED blinking time. In 8910 it's a double 256x256 loop, just not long enough for most things, so as Capn Trips says, replace by KM/RM Pause.

I think this dates back to some of the original extenders, where it worked just fine. But, the firmware in later remotes (URC-6131, for example) inhibits the LED blink routine during execution of a macro, and since the extender tricks the remote into thinking almost everything is a macro, the resulting delay time is too short to be useful.
