Bypass Power button on DLP1PICOKIT

Tracy Whittaker

HI, we are working on an embedded application using the DLP1PICOKIT and we need the DLP to power up when ever power is applied. Is there a way to program the kit to bypass the on/off button and turn on when ever power is applied to the kit?

Thanks,

    Hi Tracy,

    You can refer to PICO MAIN board schematics http://dkc3.digikey.com/PDF/Marketing/MAIN%20BOARD-12142009.pdf

    The on/off button generated LOW LEVEL is read by the MSP430 on the Pico board. Technically I would say YES if the MSP430 program is modified to ignore the LOW LEVEL and power ON the board. With such software change the board power ON as soon as main power is applied and power OFF when the main power is removed.

    As you know normally for any EVM there will be mechanical switch to power ON and OFF. The PICOKIT EVM designed accordingly. Now there is NO plan to update or modify the code or open the MSP430 code externally. So the option of programming the kit to bypass button is not possible.

    There is other option if you can electronically simulate the push button beahavior with external h/w circuit it might work.

    NOTE - Openinng the Pico kit and modifying board will loose the warranty and it will be at your own risk.

    Regards,
