detecting 2switchs and sending output to 2LEDs ona PIC

[BD]

Hi, I am new to pic programming and need help. I have to detect the status of two switchs attached to portb and send the output to two leds
on portc of the PIC.Effictively I have to generate a truth table of results
i.e. when both switches are 0 then both leds are on.and when both switchs are 1 then both leds are off.
any help greatly appreciated.

Do you want help about hardware and/or software for do this?

Try to find some PIC's books on the EDAbooks section, or by a search on Google.

Or you should specify your question.

It's a Software explaination I need. After I set up one port for the inputs and one port for the outputs should i use a Bit test command and how do i get this answer to output a 1 to the led or a 0 if there was no switch pressed.Thanks

BD,

Is it your homework?
I bet it is..... 8)

Sure You can use Bit test, and then bit clear or bit set.
But I think more easier is just to copy portb status to portc in this situation. This will work only if switch 1 is on the first portb pin and led 1 is on the first portc pin, and so on. Sure, maybe you will need to reverse bits, all depends on switch and leds connection.

Cheerz.

will i be able to just mov the value of the switch press to the o/p port
for the two switches.

Yes!
By this You will just copy status from input port ot output port. Remember about possibility of bit reverse (or xor - how You like).

Another option is to got to the Microchip website.
They got tons of examples and application notes about PIC.

Enjoy
