Wear leveling in Flash
I would search for this, but I can't find a search function... I am using a Flash chip(NOR memory). There are some user settings that change fairly frequently, and which I save to...

How to place dummy serial number in Flash at specific address?
I'm sure this has been asked many times before, and I'm sure that most of the answers have started with "why would you want to do that?", so here goes. A client of mine wants to...

Alternatives to malloc in embedded apps

emitting .elf file for production
I seem to remember reading that AS6.x has a problem generating proper .elf files that contain all the fuse and lock bit info, along with the code. Is this still the case? If so,...

Assembler files under AS6.x
Under WinAVR, stand-alone assembler files, as I recall, had to be.S (upper case). If I ask to add a new item in the form of an assembler file to my SAM4 project under AS6.1, it...

Saturating intrinsics, anyone?
Anyone know if it's possible to use the ARM C language extensions for saturation under AS6.1? I'm hoping to use the x = __usat(x, 8); sort of thing to keep rgb values in...
