Save a port number into the EEPROM?

**Fredrick** · - 20th August 2009, 07:26

I want to make a certain pin high based on a number that can be stored into a variable and the EEPROM.

Here is how to set the variables up. The read/write part is in the manual.

Code:

TRISB = %00000000
X   VAR BYTE
X = %00000100
PORTB = X

The above will make PORTB.2 high.
Change "X" and read/write to eeprom.

Is that what you are after?

Do I understand this right?

This will make PORTC.6 high?

Code:

TRISC = %00000000
X   VAR BYTE
X = %01000000
PORTB = X

And this will make PORTC.1 and PORTC.3 high?

Code:

X = %00001010
PORTB = X

Yes.
That is after you change
PORTB to PORTC

Yes of course, I missed that.
Thank you for your help.
