I want to read/write the high/low of GPIO pins of Intel Atom c3930 in Windows enterprise. I have found some information about GPIO . But I don't have any document about GPIO access, including how to set control registers and where to the high/low of pins.
Thank you for contacting Intel Embedded Community.
