help!!!

hey guys i m using the PIC16F84 with 9600 baudrate, no stop bits.
i just need a code using picbasic pro that takes 8 bites from the port A0 of the PIC and outpot them as bits on b0 through B7
the microcontroller is acting like a serial to parallel converter!

so can u plz provide me with the code?

are your sure of you protocol?

i m using the PIC16F84 with 9600 baudrate, no stop bits

What about...

TRISA=255
TRISB=0
DEFINE DEBUGIN_REG PORTA  ' Serial data come in 
DEFINE DEBUGIN_BIT 0      '     PORTA.0
DEFINE DEBUGIN_MODE 0     ' true driven mode
DEFINE DEBUG_BAUD 9600    ' 9600 BAUD
DataIn var byte

START:
      DEBUGIN DataIn
      PORTB=DaraIn
      goto start

be sure of your Serial Mode => Inverted or not
Be sure you also define your OSC speed

i m using these settings "9600,N,8,1"

OK so 9600 Bauds, No Parity, 8 databits, 1 stop bit. The above code should work depending how your data is sent and how you interface your PIC to the external world.

You may need some Modifiers => look the DEBUGIN section
You may need to change the Serial mode from True to inverted.

Keep us inform

i wrote this code but it s not working! so any ideas


N2400 con 0 'Set Serial mode
T9600 con 2 ' Set serial mode Baud Rate (T = True)
VARB0 var BYTE 'Define a variable VARB0 of type byte
TRISA=$FF 'Set port A to 1 (input)
TRISB=$00 'Set port B to 0 (output)

loop:
Serin PORTA.0,2,VARB0 ' B0 = input character Input the data serially from port A, pin0, at a Baud rate of 9600,
PORTB = VARB0 'send the data in VARB0 to PORTB (output)

PAUSE 50 'delay 50ms

Goto loop ' Forever repeat the loop

END 'end the program

Where your data come from?
Are you using an inverter like MAX232 ?
Did you connect the PIC Supply GND to the External world GND?
What is your crystal speed?
Did you set your config fuse properly?
Did you tied the MCLR pin to VCC?
Any schematic or picture of your prototype?
