Problem with peek in portB

Hi guys. I have connected 8 wires with 5 volts at the 8 pins of portB .PortC is ok.It makes only a serial communication and i have tested it.

I made that program in order to understand when the wires are 0V or 5V and which of these are 0V or 5V .For example if the RB7 takes 1 (+5 volts)and the others 0 (0volts) i want to take the number 127.

INCLUDE "modedefs.bas"

TRISB=%11111111 (i make them all inputs)
TRISC=%00000010
B0 VAR BYTE



loop:
Peek PORTB,B0

SerOut2 PORTC.0,84,["I took:",DEC B0,13,10]

GoTo loop

But it doesn't work this way.fOR EXAMPLE when i had 5 volts only at RB0 (and the others had no voltage) i took number 5 and not 1 as i expected.

hAS anybody any idea how to do it? Thanks

It's not revelant to your problem but ss you probably have PBP, you don't need to use PEEK or POKE. just use

Code:

---

MyVar var byte

MyVar=PORTB

---

By NO VOLTAGE do you mean that those pin are left floating??? IF so pull-down resistor will help.

A PIC can't read nothing... it's 1 or 0. So you must set your pin to VDD or VSS with jumper or with resistor. Common val;ue for pull-down/pull-up 10K or less. AND, personally, when i use to set a pin to VDD or VSS i add a resistor in serie for current limiting.
