I was trying to use Timer4 to create a 100ms time base for my program.
I do not have any experience with any of TS-7xxx SBC than I have
searched this forum and found "t4tics.c" source code showing how to use
Timer4. I copied pieces of this code into my program and I've found
that the time intervals are very inaccurate.
To check what happens, I've modified my program to display Timer4
counter register on the terminal's screen.
This showed that the counter register doesn't change during multiple
readings, and suddenly jumps to a new value. It holds this value for a
while and changes again.
Some times the difference between two readings would be as shorts as a
few milliseconds, some times it would be very long - close to 1 second.
Can somebody explaines what happens?
Thank you,
Marek Mierwald
