Using assembler for SAM4
Inevitably, I will want to explore the use of assembler on the SAM4. Is there any information about register usage for arguments/return values etc? This is well-documented for...

printf with floats
I know I really shouldn't have to ask this, as I have been through this before with XMega projects, but I'm having a hard time getting printf to work with floats in AS6.1 in my...

Help shows wrong prototype info
I'm not sure if this belongs here or in the ASF forum. Still learning to use AS6 and ASF, and I have to say that I don't dislike it as much as I did. One problem I've encountered...

Two "solutions" open at once?
It would be useful to me to have two AS6.1 solutions open at the same time for various cut-and-paste and comparison purposes. Is there a way to do this? I can, if push comes to...

MEMS Gyro > 200d/s
All the MEMS gyros I can find at sensible prices seem to top out at +/- 2000 degrees/second, which may not be quite enough for my application. Strange, as I'd have thought the...
