Computing pointers in gnu as I've spent a couple hours trying to complete an LED-muxing ISR in gnu assembler, and the "hi8/lo8" operators are giving me no end of pain (as usual). The context is: R30 (ZL) has... |

Debugger Disappointments Hi! In case anyone at Amtel is monitoring, I'd like to offer a few suggestions for improving the behavior of the debug/simulate features integrated into AStudio6. I've just... |

Does Atmel permit the educational use of AStudio6? I intermittently present a class for highschool kids on microcontroller programming, which has involved a simple AVR-based class project. My co-instructor and I would like to... |

Does DFU bootloader adapt to CPU clock speed? I'm thinking of migrating from AT90USB82 to an ATxmega32A4U. In order for the AT90USB82's factory-installed DFU bootloader to work, the part has to be given an 8 or 16MHz... |

A technique for pulling selfcontained modules from a library I've seen this issue discussed several times before, but not with this exact solution, so I'll barge ahead with my own reinterpretation of the wheel... Fairly often, I generate... |

Macros to enhance debuggability Over the past year, I've spent a lot of time using a JTAGICE debugging pod to watch the execution of some firmware I've developed for an ATmega324A. Most of the time, I have to... |

CPSE instruction Feel like a Friday question? As gcc is slowly winning me over, I don't do as much with assembly anymore, but this past week I've had to build some fanatically optimized routines,... |

Allocating "just enough" buffer size at link time Hi, all! I'm mildly interested in finding some elegant way to instantiate a statically-defined data buffer exactly big enough to serve the needs of the most demanding of several... |

What prevents symbolic debugging from working? Hi, all; sorry for the provocative title. I can't claim that symbolic debugging of gcc-produced code with AStudio is completely nonfunctional, because at least five or ten... |

Code generation problem with -mcall-prologues Hi, all! I'm a couple months or more into the development of an atmega324-based product, and happened across what I think is a compiler bug of a very subtle and insidious kind.... |

Technique for automatic firmware version number assignment Like Jedi crafting their own light-sabers, it seems that every software embedder devises their own scheme for stamping version numbers into firmware builds. Mine's just been... |

Linker wish list feature: feasable? I've pretty much accepted that the features of the embedded-system-specific linkers of the 1980s won't ever be restored, but here's something that I wouldn't expect to be all that... |
