The Big Ear Posted July 15, 2007 Report Share Posted July 15, 2007 What should one measure at this point (PIN21 of PIC) when the power's off? I measure ground there. Is this Ok?When the power's on, I see a "not so nice" "puls" on the RC pin.The SC pin "puls" is much nicer. Having some problems starting the interface of my SEQ...Cheers,Tom Quote Link to comment Share on other sites More sharing options...
TK. Posted July 15, 2007 Report Share Posted July 15, 2007 Hi Tom,how do you measure the pins, with a scope, or just with a multimeter?I would propose to check the continuity when all ICs are removed from the sockets. In this case, you shouldn't measure a "short" between pin 21 and ground (measuring result: > 0 ohm or even maximum resistance)Note that there is a troubleshooting page: http://www.midibox.org/dokuwiki/doku.php?id=din_moduleBest Regards, Thorsten.

The Big Ear Posted July 15, 2007 Author Report Share Posted July 15, 2007 I removed the PIC, still ground. disconnected the leds, no longer ground.I've got a dout problem. But the din's are working now ;-)Cheers,Tom Quote Link to comment Share on other sites More sharing options...
