About flash memory of the OpenRB-150

For these types of questions, the key concept is to remember that the OpenRB-150 is a variant of the Arduino MKR ZERO (i.e. SAMD21 controller). So when I made a search on Arduino references to Flash Storage for the MKR ZERO, I found these links:

So I just followed their instructions:

  1. Use the Arduino Library Manager to install the FlashStorage_SAMD library (currently V. 1.3.2).

  1. Go to your user Documents folder on Windows, i.e.
    C:\Users\username\Documents\Arduino\libraries\FlashStorage_SAMD\examples\FlashStoreAndRetrieve to find the example sketch “FlashStoreAndRetrieve.ino”.

  1. I have verified that this sketch compiled and downloaded to the OpenRB-150 OK.

  2. This sketch is designed to add ONE to the current value found in EEPROM’s address “0”, each time that it is executed.

First run then I pushed reset button on OpenRB-150

Second run then I pushed reset button on OpenRB-150

Then I completely Powered Off the OpenRB-150 and then re-enabled power to the 150 and ran the sketch again

So this example sketch is working as it is supposed to :grinning:
