No Atmel simulator for AVR-Dx family? Closest alternative?
Am I missing something, or is the whole AVR-Dx family not supported by the Atmel simulator? I'm using an AVR128DB. When I open the Device Programming window, and change the tool...

Any clever way to mimic an output enable for an AVR output?
I have an AVR128DB48 outputting a signal on a pin, and depending on the state, the signal might be coming from one of two different timer/counters, or from a CCL. There's also an...

when does avr-gcc use instructions like SWAP, BST, ROL?
On browsing through the AVR instruction manual, I see several interesting and useful instructions that don't map readily to any simple C code. I'm curious if and when avr-gcc...

AVR-Dx accessing Flash in CPU Data Space
The AVR-Dx family support mapping some of flash into CPU data space, so it can be accessed like RAM using the LD instruction instead of LPM. In the AVR128DB datasheet this is...

debugging a crash without a hardware debugger - options?
I've found a 100% reproducible crash bug in my ATMEGA1284P project, where by "crash" I mean my custom AVR board either locks up, or appears to jump back to the beginning of main...

stack update is not interrupt-safe?
I'm trying to chase down a bug in my C code for the AVR Atmega1284. Every so often, it looks like I may be getting a corrupted stack. Looking at the compiler-generated code, I see...
