Thomas Posted July 2, 2006 Report Share Posted July 2, 2006 Hallo!I have a problem with the shiftregister of one PIC. The DIN-shiftregister does not work. When I press button 8 on the first shiftregister it is like pressing all 40 buttons, but pressing onother button has no effect. (The DOUT register do not work, too.)I have no scope, so I messured the voltage on pins D3 and D2 with a multimeter. I get 0.16V and 2.55V. BUT on the other pic that works I messure 0.08V and 3.5V. I changed the EQU of the pins in the MIOS-src, compiled a new MIOS with interchanged D2 and D3 and I messured 2.55V and 0.16V as expected. The pins have changed. All connections seems ok, and even worse, it had worked last week! Something must be broken and I could find it. I replaced the 165, too.
