manipulating bits on PORTx

[dvfer]

Is there a way to manipulate bits on any port as a vector??

Hi,

Please, can you tell me what exactly did you have in mind ?

Well, I would like to do somthing like this:

I'm using a pic16F887..


for (i=0;i<8;i++) {
PORTB = 1;
delay_ms(1000);
}


This code will generate an Error when compiled, but, is there a way to manipulate a register's bits like an array?? Do I have to write my own library??

And also I know that it is not possible to declare a bit type array :'(..




Thanks for fast respond...

Hi,

Well, you could do this in this way :

Code: Select all

char i;
char array[] = {1,2,4,8,16,32,64,128,255};

void main() {
  for (i=0;i<8;i++) {
    PORTB = array[i];
  }
}

Basically, you assign to the PORTB predefined values from the declared vector (array).
