Hi all,

I'm working on a DTMF decoder board using a Mitel 8870 decoder IC and 16F628, I'm having problems getting the PIC to see the Strobe from pin 15 of the 8870 using port A.0 on the PIC, has anyone got any ideas or experience with the 16f628 & 8870?

Also any code snippets in PBP may be useful?

I need to get this working ASAP as it's for the local Amateur TV Repeater which is due to go on air in May.

Thanks for any advise

Regards,

Jim
