Hi Chris & Jonny;

Well that last gremlin was a little bit of an SOB..... a case when two or more events dynamically ligned up to run at the exact same clock tick, one would get serviced and the other lost its clock reference for 256 ticks. Anyhow, its been running without any hiccup for half the day. At the end here I arbitrarily expanded the number of UARTs to 5 transmitting and one receiving, all independently and simultaneously at 9600 baud, including generation of their own transmit data set. Every transmitter was triggered repeatedly every 1.2 milliseconds, so there was a bag of data going out.

Then scoping the trivial task routine (essentially the looper that waits for the next task's time to come up), and there are BAGs of cycles left; I'd bet were only consuming 10% or 20% (not calculated just a peek from the scope) of the processor, including the OS!

This is gonna be great!

So I'm doing some polishing now and still will want to do some bullet proofing before I issue a general release. In a new post topic I imagine.

I'd appreciate getting a few guru's to beat up on this..... any takers? My guess is that at this point at least it's certainly not for beginners..... a good scope or logic analyzer will be a huge asset.

Also I still need to create some explanations/limits/rules.

Cheers,

Peter (pjv)
