That's because your initializer is a string, and addr_t isn't a
string. It's a structure.
Yes.
And I don't know enough about IAR but it looks like the .dat file would
be used on the command line.
For IAR:
-DTHIS_DEVICE_ADDRESS="{0x97, 0x56, 0x34, 0x12}" works
For gcc:
-DTHIS_DEVICE_ADDRESS="{{0x97, 0x56, 0x34, 0x12}}" works
As a define::
#define THIS_DEVICE_ADDRESS {{0x97, 0x56, 0x34, 0x12}}
to initialize the structure.
Best, Dan.
