ATtiny, input protection, LED, sync
Great input, thanks all! I entered into this experiment aware that tying the load to > Vcc+0.5 could be a bad idea, so I spent some time thinking about what might happen. Truth be...

Need help using the ATTiny841 with avrdude
dkinzer wrote:Moreover, the AVR Toolchain v3.4.2 says that it supports the tiny841 (not the tiny441, however) but there are no include files for them. Perhaps fixed in a later...

I2C library for attiny84
Don, thanks for that driver; I found it a few weeks ago and it's been most helpful with my Tiny44A-based analog to digital converter board.

Serial comm lib
I've been doing the Eclipse/AVR thing too... for ATtinys though. Glad you got some help. I, too, will be digging around looking for libs so I don't have to reinvent the wheel. :)...

problem in PCB
What chip? What package? Obviously QFN would be hard, PTH easy, QFP in between. You can just try it with wires and see what happens I guess. Tie AGND(s) back to one point? I dunno...

Interconnecting multiple AVRs
You can have 127 device addresses on I2C. It's an open collector protocol so all the devices are doing is pulling down the signal to ground (or nearly so). I'm sure there's I2C...

Help me with a fan driver please
So, NPN as a low side driver. I've attempted to drive motors with BJTs with different motor voltage and signal/control voltage and run into various issues that are vague and fuzzy...

No success making blink on ATtiny84
I will try to help if I can. Simulator -- If you were using AVR Studio you'd have access to a simulator that you could check your code, check resisters as you step through code,...

I2C/TWI - hunt for understanding
The 7-bit / 8-bit address thing has bitten me in the past too. It looks like Arduino uses the 7-bit address. I'm not familiar with Fleury's TWI lib. Typical bus speed on I2C is...

Using Eeprom of Atmega 32
It seems to me like you are trying to figure out what data structures to use to store the data? The eeprom is sort of a serialized bunch of data, basically a big array or fifo....

What IDE do you use for programming AVR controllers?
IMHO Emacs qualifies as a (quite fine) IDE .. what I "grew up with" and also have used it with AVR invoking make within the editor, etc.
