    this is so unfortunate..my vdip2 is suddenly not working...

    the status LEDs do not light when i turn the circuit on.. it also does not respond when i insert flash drives...

    i tried connecting it to the pc's serial port to see if the LEDs are just busted, but nothing happend. its as if there's nothing connected to the serial port.

    i've measured the voltage supplied and i saw that the voltage was correct.

    did anyone experience this? can there still be a remedy for this module?

    On the VDIP1 there is an active low reset pin. Can not remember the exact pin but I think it is 22. Double check for the VDIP2 and give that a try.

    And it gets to high state by . . . a Pullup ? WPU ? Fear ? Which is to ask, can it get there ? Or is it locked to reset in perpetuity ?

    are you suggesting to try pullup instead of pull down? done that...didn't work..

    If I understood you correctly, and I am not sure I did, your push button switches ground the ports. If that is true, then yes, a pull up resistor, either internal (wpu) or external would seem to be in order. If your push buttons make the ports go high, then a pull down resistor would be required.

    The VDIP2 might be different but on the VDIP1 the reset pin is left floating when not in use. Seems strange yes but....

    Sounds like a bad conection or the magic smoke got out.
