Any possible way to program via twi?
Hi. Candidate for dumb question of the year here... Is there any way to program a Mega AVR via twi/i2c instead of SPI? I imagine not... as I can't Google anything suggesting you...

Can Atmega generate clock signal @ specified voltage?
I'm just beginning with AVR. Interfacing with an backlight driver IC. That IC needs two clock signals, one at 20khz and one at 1khz (neither figure need be exact) and it...

Atmega**U4 (USB chips). Confused about how to power.
Hi. Taking a look at the Atmega32U4 datasheet sections 21.3.1 and 21.3.2, they make a distinction between bus-powered and self-powered devices. I would like my device to be......

usbasp on a different Mega?
I'm sure this is a stupid question. I've really got very little experience with Atmel chips and next to no experience with AVR programming. I've build a custom usbAsp device but...

usbAsp connection. SCK with resistor in the way
Hi. Let's say I have a device that I can't alter. It has a Mega and I want to program it. All good but the SCK. For argument's sake, let's say the only place I can make the SCK...

Atmega64 rebooting with a power spike? Or is it a brownout?
Hi. While I have some experience with electronics, power isn't an area I know a lot about, nor are Atmel chips. I'm sure this is basic for many of you. I have a circuit that...

Perplexed on why it works when I touch it?
Hi. I'm trying my hand at a small project just following a datasheet schematic (see attached). I've made two different board layouts following the same schematic. The only...

Swapping an Atmega64 with an Atmega128 - firmware compatible
Hi. I'm not much of a firmware guys and I really have very little experience with Atmel chips. We have a device that has an Atmega64A. It has been suggested that we could replace...

Can fuses change "on their own"?
On a different forum, which is populated with people that are by no means experts in this stuff (which is why I'm posting here), including myself, there's a discussion going...

USBAsp problems... how to diagnose?
Hi. I'm trying to make a custom board that incorporates, among other things, a USBAsp programmer. The schematics appeared pretty straight forward and I've double and tripled...
