Hi,
I have an an idea floating in my head, regardig timing with GPS clocks.
I'm working on a project that uses PICs, and INTERRUPTS.
These interrupts have various timings, and is difficult for me to visualise.
There are 4xPICs on 2x PCBs all talking in different ways, radio etc, and timing can be an issue.
As both PCBs have a GPS, which has an accurate clock, what I want to know is: could a program be timed all the way through, so interrupts aren't needed?
Here's an Oscilloscope view of the 1sec time plus the 200Ms times of the GPS sentences. The Sentences at the bottom, start in the centre of the 1sec time.
