Timer delayed ADC conversions
Ah, but that would be the easy approach, and no fun! :D Two reasons, actually (now that I think about it): -I want to learn to use interrupts in a good way, and this project...

ATtiny13, fuses and ISP programming
Hmm... I might have misunderstood your question before, as if you were looking for ways to disable SPI reporogramming. Still, I guess the answers hold. :) What's the internal...

Timer delayed ADC conversions
Quote:The OC triggers apply to timer 0, so I expect the TOV trigger applies to timer 0 also. Ah, I should have known... of course I would have to pay for trying to escape reading...

Turn on ATMEGA8515L Timer
Hmm - about the reset pin. Most AVR's have internal pullups on the RESET line, as does the ATMEGA8515, so external resistors shouldn't be neccessary. I'm not familiar with the...

How to handle startup transient state of IO pin.
I'm not sure how they implement the Hi-Z, but nothing (except for relays) is ever not connected to either VCC or GND, it's just the resistance that can be very large. If you're...

Line length / driver questions
Of course, Kartman! How could I miss DMX512? That'd be way cool too, since it would support controlled dimming of the diodes - but you would need an AVR on each jixel. :D If you...

ATtiny13, fuses and ISP programming
I don't know about the tiny13, but on my tiny45 there is a SPIEN (SPI ENable) fuse. Also, if you don't need external reset, you might be able to program the RSTDISBL (Reset...

Line length / driver questions
I'll pick up the power supply question then... If I understand correctly, you're going to use about 4000 LED's? That's quite a few... :) A common number when calculating with LED'...

Why 0ohm SMD resistors? Butterfly VCP question too
So I had a quick peek at the schematic for the butterfly, and I actually think the design was intentional, even though it seems strange. The temperature measurement and the light...

Did I Fry my Butterfly?
Just to make sure I understand correctly: Does the servo have a three wire connection? One power, one ground, and one control? If it does, there should be little risk of actually...

Dragon: Getting ISP frequency parameters.. FAILED!
This was odd to me. As I recall we managed to do this in a related project with another Dragon, but hooking up the MCU seemed to fix this. Thank you all for your help! Where is...

Dragon: Getting ISP frequency parameters.. FAILED!
bloody-orc: Erm... no? Isn't the ISP frequency programmed on the Dragon itself? Also... what manual? All I can find is the AVR Tools Help, and that isn't very helpful when it...
