    I need to be able to connect several discrete I/O and a few analog I/O lines to hardware devices. Has anyone done this using the eXper Kit? I know there are GPIO lines available on the ext headers, but was wondering if it had been done before.

    Please look at the breakout boards on http://www.createnewstuff.com

    The TI Breakout Board - Wattson looks interesting, but limited ADC inputs apparently:
    "It can monitor the following INA219 ADCs:

    U14: MAIN_BATT_IN power rail

    U15: 1.2V Switcher power rail

    U16: I/O Switcher power rail (3.3V_or_1.8V)

    U17: 1.8V Switcher power rail"

    The TI Breakout Board - AM3517 looks very flexible to access all extend ports, but I have 6 ADC sensor signals to read from embedded code on the AM3517. I do not see that this is possible with this configuration / hardware. What am I missing?

    "J21: Display SubSystem(DSS), CCDC, UART1 UART2, UART3, SD port 1, SD port 2
    J22: GPMC bus, I2C2, I2C, McBSP1, McBSP2, SPI1, SPI2,
    J23: McBSP3, McBSP4, I2C1, Power Management I2C, Reset Output, WL1271 UART for Wifi & BT debug, JTAG signals, Boot control pins, ETK signals"
