Message Triggering INT_EXT1 on H_TO_L Posted: Mon Sep 12, 2005 10:01 am
(sorry if this double posts, I got an error the first time and it didn't seem to go through) I'm using an 18f452. I already have INT_EXT set to trigger on H_TO_L using EXT_INT_EDGE() but it seems that INT_EXT1 is set by default to trigger on L_TO_H. How would I go about changing INT_EXT1 to trigger on H_TO_L? Is there a command like EXT_INT_EDGE() that I am missing? Thanks Ttelmah Guest

Have you read the manual entry for 'ext_int_edge'?. It supports a second variable, on chips that have more than one interrupt. So you just code: EXT_INT_EDGE(0, H_TO_L); EXT_INT_EDGE(1, H_TO_L); If the first value is omitted it sets the value for INT0. Best Wishes Display posts from previous: All Posts
