Atmel ICE Can't Talk to a ATmeg8U2 on a Breadboard, New (_and_ old) Setup
Swapped chips. Still nuttin'. I'm building up a new prototype board with a fresh chip, but I don't have much hope that #3 will magically work.

Atmel ICE Can't Talk to a ATmeg8U2 on a Breadboard, New (_and_ old) Setup
All right, I had a pin connected wrong. I also verified that it is not a problem with the squid cable itself. On my scope I, if I watch the ICE try to read the device signature, I...

Atmel ICE Can't Talk to a ATmeg8U2 on a Breadboard, New (_and_ old) Setup
Well, after uninstalling everything, verifying that the ICE and the Dragon had no driver available at all, and reinstalling 7.0.1645 from scratch, I was able to get the old...

Atmel ICE Can't Talk to a ATmeg8U2 on a Breadboard, New (_and_ old) Setup
Given that the old breadboard project doesn't work either, leading me to believe it is a software problem, I am going to try this next: uninstall everything from Atmel I can...

Atmel ICE Can't Talk to a ATmeg8U2 on a Breadboard, New (_and_ old) Setup
As I mentioned, 125. I can't read the fuses so I don't know for sure how the micro is set, but the datasheet says it ships set for the internal RC 8.0MHz oscillator with CKDIV8 on...

Atmel JTAGICE3, ATMELICE not working anymore in Studio7
I don't have a solution but it seems as though we may be having the exact same problem. I have an old breadboard that used to work perfectly, programming and debugging with ISP/...

ATTiny461 -- doing ADC while changing voltage reference on the fly?
Talking to our EE, the power supply design is because (1) LiPo power source... (2) several other devices on the board need a +5V supply, so we didn't want to have to do logic-...

ATTiny461 -- doing ADC while changing voltage reference on the fly?
>ADC clock?  Show some code.   I'm pretty sure it wasn't that. I think it was not having any decoupling on VCC at all. After I added some caps to my prototype board,...

ATTiny461 -- doing ADC while changing voltage reference on the fly?
Yeah, our EE selected the automotive SOIC part for the actual board. For prototyping I actually have a through-hole part, to make my life easier. Why the data sheets differ so...

ATTiny461 -- doing ADC while changing voltage reference on the fly?
> Y'all need to decide--it is your app.  But IME "battery-powered" and "regulator" don't fit together.  I suppose you could have a big battery such as 12V SLA and you...

ATTiny461 -- doing ADC while changing voltage reference on the fly?
I appreciate the clarification, and I believe you.   Atmel's datasheets are not as clear as they could be about this.   My datasheet is downloaded directly from this...

>You didn't mention your sampling rate, which might impact your approach.   Sampling rate is low -- I think 100Hz would actually be plenty.   > Depending upon just...
