Guest Triggering INT_EXT1 on H_TO_LPosted: 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

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
