all LEDs are on, core vreg hot,then shuts down

[Steven_C]

:'( I finally finished soldering the rest of the buttons in, now all the LED's are on all the time!!

pin 19 of the pic is always at +5v (S0, of JP8)

could someone else measure this, and tell me if this is normal?

I am using midibox LC

Hi Steve,

Pin 19 drives a high frequency signal, it's not possible to measure a meaningfull value there, only a scope would help to make the waveform visible.

However, the easiest method to search for the error should be to disconnect the modules and connect every DINX4 and DOUTX4 again successively.

Hey Thorsten,

Thanks for the reply, it is appreciated!

I tried connecting the modules one by one, but even the first one was always on! So I tried another PIC, and now it is working great!! ;D as for the real cause...

-maybe I damaged the PIC (Short somewhere?)

-maybe an offcut of wire caused a short and when I replaced the PIC it may have dislodged the short? (I turned the board upside down and shook it, as I noticed a few small bits of metal/solder on it)

anyway, I'm happy now!! ;D
