PIC code help

[mr. mister]

i have written a PIC code and need help in knowing if this bit i have written is correct

Processor: 16F84A

basically i am trying to set the MSB of port b high after a series of events, would this be right?

MOVLW b'10000000' ;loading that binary value into the working register
MOVFW portb ;loading this value into port B i hope will set RB7 high
MOVLW 0FF
CALL delay

please i need urgent help :x :x :x

mr.mister,
You should change

MOVFW portb ;

to

MOVWF portb ; as this moves the value in w to the file register portb.

MOVFW does the opposite transfer which is not what you want.

Also, MOVLW 0FF is not right. It should be MOVLW 0xFF, the 0x indicates that the number is hex.

You're welcome,

You should use the Micro Controllers forum. This forum is not for Micro Controllers. You should receive a better response in that forum.

Go to the main menu, it is the fourth one.
