#34672 - RE: Ext0 doesn\\\'t work |
When I don't disable IT0 it works...but it doesn't seem to work with IT0=1
Level Trigger (ITn = 0) should only be used for interrupts where the ISR clear the condition for the interrupt. Please clarify above statement are you talking about doing it in the ISR, in the initialize or what. I'm sorry to say that I don't have 'the bible'. I've ordered it though...but it takes quite long. The download address is in links (look left). Do not waste time to download the complete "bible" it is enormous, just get ch 1-3 (separate links) Erik PS I did not know it was still available in print. |
