Timer Interrupt for Connect ME 9210 Embedded Linux

0 votes
Hello I am new to this Digi Connect ME 9210
I need to generate a timer interrupt to handle produce change output every 8ms (very precise) but so far I have been unlucky in finding examples or documentation on how to do it.

I would be very glad if you could share some tips and / or assistance.

if you just want to toggle a GPIO every 8ms, you should write a kernel driver interrupt handler using on of the ME 9210 hardware timers (see hardware reference manual or NS9210 CPU).
