    Hello Everybody

    I am trying to write debounce code for switch 1.

    Switch 1 is connected to port b pin 2 through jumper.

    The problem is that the DATAIN_B register does not chang its value after I press switch 1 (Port B2 pin configured as GP I/O mode).

    The declaration of port B are :

    PSD_reg.CONTROL_B &= 0x00;

    PSD_reg.DIRECTION_B &= 0x00;

    if(PSD_reg.DATAIN_B==0x2)// Checkes bit 2 in port B

    Thank you very much Kobi.
