Just a beginner so sorry if this is very basic question (I can't seem to find the required docs anywhere ;

How do I enable EXTINT 5 using ST Libraries ? (Using the MCB-STR9 Eval Board and I would like to use the Push Buttons, s3 and s2 (EXINT5 and EXINT6)

Hi cdixon,

Try the following post if you still haven't been able to solve your problem.

Beware that you can only use one of the two buttons SCU WKUPSEL register does not allow you to select more than one. For documentation, check out

. The first three pdfs are your most valuable information source.

However, I am also facing some side effects problems, but you can get a starting idea of how to make use of your push buttons.
