16f872. config ports and serin question.

Hi there.
I want to set up a 16f872 so that all ports are digital. I have had trouble with analogue inputs on a 14 pin package and disabled it with this:
ANSEL = 0
What configuration do I need to make all ports digital i/o/ports.

Secondly. I am sending 2 bytes from a pc and I want to output these two bytes on portb and portc.

Is it ok to simply do this:

serin portb.2,6, mylowbyte
serin portb.2,6, myhihgbyte
portb = mylowbyte
portc = myhighbyte

AM I right in thinking that the pic will sit there doing nothing until it receives a character on the input pin? I am sending two bytes from my pc software every time someone pushes a foot pedal. Is there anything that I should know here/

According to the datasheet......
ADCON1 = 7 ' Set all pins to digital , then use TRIS to set input or output

As for serial output. Look at the manual for serout commands, this should get you what you need.

Hello Kitcat,

On the 16F872 only Port A pins are analog or digital. The ADCON1=7 command sets PortA to all digital. If you are looking for serial operation, any pin on the chip can be used as a serial I/O pin. If you intend to use a hardware serial setup with a RS232 level shifter then you want to use RC.6 for Tx and RC.7 for Rx. I don't mean to sound like a broken record but you should go to microchip.com and download the datasheet on the 16F872 to get all the info you will need to work with this uP.
