I'm trying to implement a fast SPI slave port for data logging on a TS-
7200. The slave port is up and running fine, but I get overruns every
so often because the processor is being stolen away from my code and
running what I assume are OS processes. This is undesireable for my
particular application. What I want to do is turn off interrupts while
I'm receiving, but I don't think that is possible, if it is does anyone
know how?
What I was thinking of doing as an alternative is to write an interrupt
service routine for my code that will make it high priority and preempt
all the other interrupts that are currently giving me fits. I'm having
trouble wading through the code that is on this site and it seems bulky
for what I'm trying to do. Has anyone implemented a simple interrupt
like this and if so can you post or send me some example code.
Thanks for any help you can give me
