Thanks for the work!
One minor change requested in the main() for readability.

Though, this is an example that's meant to be run on all devices. The inclusion of additional image samples might not fit on the tiniest devices. My recommendation is holding back this PR until tests have been conduced for cortex M0 devices.

A macro define or a const variable is a better idea here.
