Question about GPIO

    I would need to use GPIO 0-12 as digital input. I have seen in the hardware manual that this pins are used for the keyboard too. I guess some of them are configured as outputs so this issue could cause electrical conflicts.


    I'm not using a keyboard for my application but anyway, should I make any special configuration to use these pins for my purpose? Is it safe to use them?


    Best regards,

    Hi,


    you can use all 20 IOs as digital input in principle. Just configure the digital IOs in registry as you want to use them and make sure that the matrix-keyboard is disabled (which is default). You can find a description how to configure digital IO and matrix keyboard at http://www.fs-net.de/cgi-bin/c…tDCU_DeviceDriver_eng.pdf.
