PGA970: Automatic Programm run without new load from the PC

Part Number: PGA970

Hi,
Im trying to make my written programm functioning without the usage of my PC. I think my attempt of using the FRAMbecause its non temporary was right. I used the genreated HEX-file from my functionating build and loaded it into the FRAM via PGA970GUI and verified it. first thing to notice, even when verified my code always seems to stop when swichting to Digital Interface which means that my idea with the hex file isn't working.
Did I do something wrong? In my opinion it should be the way to go when you want your board to keep its functionality after a power loss.

Regards,

Paul

    Hi Paul,

    If you enable the digital interface through the GUI, this also places the internal microcontroller in reset. This is because both the M0 and the digital interfaces cannot be allowed to access the configuration registers at the same time. 

    Do you intend to use the digital interface to access registers like the DEMOD data in your application? If so, the firmware could be used to set up an initial register configuration at powerup, but will have to be stopped to access the digital interface afterward.

    Am I understanding your application and your concern correctly? Please let me know if your question is about something different.

    Regards,

    Scott
