Can anyone please advise me on how I can set one of the GPIO lines on the
Connex (via the breakout) as an "non maskable interrupt"?
The reason for doing that is because I'll need to make sure that the
incoming digital signal (from an external source) is not being interrupted
by any events when running the gumstix.
I'm sorry that I'm a newbie to these sort of programming and am trying to
find a quick method to program the GPIOs. Currently I'm using the sample
codes (http://docwiki.gumstix.org/Sample_code/C/gpregs) given in the gumstix
webpage to configure the individual GPIO lines. How should I approach the
problem using the existing configuration?
Any advice will be greatly appreciated.
