Basic question about Aliases

[dbachman]

I am still on a learning curve here so please bear with me.

I have been trying to make use of byte0 and byte1. Shouldn't this flash leds on portb? Must be doing something wrong.

Thanks, Don

TRISB = %00000000

loop:   

x var word
x = %00101111
       
       portb = x.byte0          
       pause 1000
       portb = x.byte1
       pause 500
       
      
        Goto loop             
  End

You've defined x as a word. That's 16 bits. You've assigned 8 bits of X. PortB is 8 bits too. X.Byte0 chooses the lower 8 bits of X and X.Byte1 chooses the higher 8 bits of X.

Thanks Jerson,

I figured it was somethig simple like that. Thanks for taking the time to reply

Also, I was trying to figure if this is how this worked.

X = %00001111

X = X | %010000000

Is %01001111 the value of X now?

Thanks, Don

[Jerson]

that is correct.
