Screwed the clock settings? I have an ET-BASE AVR (ATMega128) board from Futurelec which I decided to program the fuses as: SUT1:0 - 11 CKSEL3:0 1111 CKOPT - 1 After doing this, it will no longer communicate... |

ISR procedure length Is there a limit to how large interrupt procedures can be (aside from the normal limits of flash RAM?) Reason I ask, is because if I seem to make it too long (for example on my... |

Beating my head against the wall! Why doesn't this work? ATMega48. Having some issues with boolean comparisons, I guess. This will work for the first state change, either going into programming mode or into calibration mode - but will... |

Executing code stored elsewhere Noob question: How would one go about executing code from a location other than the AVR's on-board flash memory (ie, a CompactFlash card or external flash chip). Is this possible... |

Schematic for a good AVR power supply I was wondering if anyone has a good schematic for what a good AVR power supply should look like, assuming input from a noisy 10-15VDC source (like a wall transformer) along with... |

ATMega48 - ADC0 (PC0) sinking 13mA current? Any idea why ADC0 would sink 13mA current (verified on the STK500 LED port - LED0 lights up when the PORTC header is connected to the LED header) while the port should be... |

Where to get ATMega(xxx) Automotives? Does anyone know if there are there ANY distributors that carry ATMega automotive versions? I can order an AT90CAN series from Digi-Key.... so you'd think they'd carry the Mega48... |

10-bit fast PWM help Hello, I'm trying to use 10-bit non-inverting fast PWM (on an ATMega48) to generate output on OC1A. I'm also doing a 10-bit ADC (AREF is VCC) on one of the ADC inputs.... |

Fried Mega48 runs fine in STK500 but not otherwise Okay, I inserted my mega48 into my solderless breadboard wrong and accidentally put +5V to PD4 and GND to Vcc. Now, when I put the Mega48 in correctly, PD4 is the only pin that... |

ATMega48 - PORTB and PORTC only outputting 6 LSB's What do I have to do to be able to use PB6, PB7, PC6 and PC7 as outputs? PORTD is the only port I've been able to get all 8 LED's to turn on (programming with on the STK500.) On... |
