Measure supply voltage on ATtiny24 Am I right in thinking that I can check the supply voltage(battery) on my ATTiny24 circuit by setting Aref to Vcc and selecting the internal reference as the input channel? And... |

14 pin SOIC adapter for STK600 Does anyone make a 14 pin SOIC adapter for the STK600? I may need to program some ATtiny24/44/84 parts, and the final PCB is likely to be too tight on space for an ISP connector,... |

Small problem with volatile. I have 3 or four 16 bit variables that are used as timers. Because they are decremented to zero(and not below) in an ISR, they are declared as volatile. The problem I have is that... |

JTAG versus ISP Here's a simple question that I could probably answer by reading datasheets. I may shortly have the luxury, for the first time in my life, of using JTAG(JTAG ICEMKII) for a... |

Persuading GCC to put my asm fonts/strings in low 64K of 128 As I understand things, GCC will attempt to place PROGMEM stuff in the lower 64K of an Mega1281's FLASH memory. My program has, for efficiency reasons, a couple of fonts and some... |

Problem with brown out I have enabled the brown-out option, but still he refuses to stand down. What's going on? |

Can I stop GCC using a certain area of code space? Because of a minor cockup(by me) with a bootloader, I have ended up unable to bootload anything into the 0xfc00 - 0xffff region of a Mega1281. You can probably guess how this... |

Over-aggressive inlining violated my TWI bus timing... and now I feel dirty. Or so I believe, I haven't managed to quite get to the bottom of this yet, but using the latest version of WinAVR (I have been using 20060125 since, well,... |

WinAVR with AVR Studio I don't know whether this rightly fits in this forum or the AVR Studio one, but it's such a dumb question that it probably doesn't matter anyway... I have been using WinAVR for... |

Mirroring a VGA signal. An old client of mine has an application where he wants to mirror a VGA(SVGA?) display, so that it can be viewed in a mirror. Apparently, a lot of smaller LCD screens have a... |

Union of structures? This is more a general C question than GCC specific. I have a 32 byte block of data that will eventually be written to a TWI EEPROM for logging purposes. However, depending on the... |

Does wdt_enable(x) preserve the state of the WDIE bit? Errr... I'm not sure how to add anything to the subject - I want to use the watchdog interrupt facility on a Mega1281, but I'm not entirely sure if, when I change the watchdog... |
