How can I read the unique device Id of my microcontroller? I didn't find any function in the firmware guide. Any suggestion?

Thanks.

There isn't one to read.

e.g. as follows:

#define U_ID_0 (*(vu32*) 0x1FFFF7E8) #define U_ID_1 (*(vu32*) 0x1FFFF7EC) #define U_ID_2 (*(vu32*) 0x1FFFF7F0) printf (''Unique ID

I stand corrected! I'm sure there was a thread a while ago about this, and there wasn't one. I must be imagining things.
