Friends i need urgently assistant.

I have the professional development board and i use all the mainio and auxio pins to connect stepper motors.
For a reason that i dont understand the MAINIOC command for the RBO RB1 RB2 RB3 PINS is not working.
What i need is if anybody knows what is the command for reference to the RA0 RA1 RA2 RA3 (MAINIO or AUXIO)? because they are the only empty pins left on my project .



thanks a lot......

    Attach the code that you're using when trying to do this.
    MAINIO, AUXIO,...

    Which Basic Stamp module are you using on the development board? You must have a BS-2p 40 for these commands to work.

    Link here: http://www.parallax.com/Store/Microcontrollers/BASICStampModules/tabid/134/CategoryID/9/List/0/SortField/0/Level/a/ProductID/8/Default.aspx

    I hope this helps!

    Look at the schematic for the Professional Development Board, particularly pages 7 and 9. You will see that RA0-RA3 are not used with the BS2p40. They're for use with an SX microcontroller only. Page 9 shows that the BS2p40 main I/O pins are connected to P0-P7 and RB0-RB7 and the auxiliary I/O pins are connected to RC0-RC7 and P8-P15.
