Access to program-writeable flash?

Other Parts Discussed in Thread: CONTROLSUITE

Hi,

I'm wondering if there is any non-volatile memory that the F28069M program can write to in order to do something like save motor parameters. I'd like to have the motor ID parameters saved on the board by my application, so that I don't have to maintain different binaries for each motor. Is there a way to do this? Or should I include an eeprom or some other memory on my next board revision?

Thanks,

Steve

    I could not locate any document for the chip. Even with the other chips, we would have broken URLs.

    But here is the example you could have in your drive C:

    Steve,

    If you have a few motors that you set-up off-line you can just store them each as a set of UserParams, then use logic in your system to determine which to load. That's assuming you have enough Flash memory remaining in your F28069M device.

    If you want to be able to ID a motor in system and then save these values in the motor controller / inverter for future use, you could potentially use a single block of flash that you write (using the Flash API).  If you are going to have this as a continuous feature of your product you may want to consider using an EEPROM for storage though, that way you can have more motors parameter sets available to store.
