Title: Problem with PBasic 'OUT' command
Post by: Barnaby on December 28, 2007, 12:13:51 PM

Hi,
I've just recieved an ancient copy of PowerBasic, and the most useful commands for robotics seem to be the input and 'OUT' commands.  The syntax is stated as:

OUT port#, byte

But I'm stuck with the port# bit.  How do you find what number to put there to specify a paralell port or com port.  How do you do it?
Thanks,
Barnaby

The datasheet for your microcontroller will specify when pin goes to which port letter and number.

If you can't find a datasheet, you can probably guess and measure the pins with a multimeter to see which one changes.

Thanks, but I meant computer port.  I can't find out how to specify a computer port to output the data to.

To have easy use of a computers serial or parallel port just use RoboRealm or even Visual Basic

start -> settings -> control panel -> system -> hardware -> device manager
