AVR's with PLL/high speed PWM
I'm not finding the high speed PWM function in the parametric search here in the device section and having trouble finding all AVR's (preferably beefy ones) that support it. Are...

AVR co-processor's
Can anyone recommend an analog co-processor to use with an AVR? I'm interested in building an AVR centric multi-meter for a personal project but I don't want to build a lot of...

Highly variable external clock
The data sheet for AVR's I've seen that support an external clock say that you shouldn't change the clock frequency by more than 2% between any two clock periods otherwise...

AVR Ibis models
There was a thread the other day about new IBIS models for AVR's http://www.avrfreaks.net/index.p... I was wondering if someone could post images of the curves at various VCC's/...

tiny15/tiny85 high speed clock
Has anyone with a good scope ever taken a look at the actual signal a tiny15 or tiny85 outputs when it's running 'flat out' in PWM mode at it's highest frequency? A tiny15 has a...

Processing + M128 == wiring
Based on Processing (a Java based very high level programming language) but with a Mega128 powered I/O board. Ostensibly for the artisticly inclined but I thought it was a novell...

tiny15 FM modulator
This is just something I've had running through my head for a while. Has anyone ever thought of using a tiny15's high speed PWM output at it's maximum clock rate and then using...

O.T. Polyethylene/Aluminum capacitors
I've always been curious about home brewing capacitors. I would like to experiment with polyethylene and aluminum for capacitor materials. We have large rolls of poly stretch film...

ADC's sample and hold capacitor
The ADC on AVR's use a sample and hold circuit for it's ADC conversion. Does anyone know what the recommended/max impedance for that sample and hold circuit is? I just noticed the...

AVR and PC graphical interaction
This is not directly AVR related but I think exceptionally useful to the hobbyist and professional alike that use AVR's. I've posted multiple times on this and several other...

Spice model for tiny15 PWM output
I need a very acurate spice model for the tiny15's PWM output. Specifically the high speed PWM output. I need to to know the true ON resistance of the I/O port, it's series...

AVR I/O pin capacitance considerations
I know this might seem a bit on the paranoid side.. but diodes have a certain level of capacitance between their P-N junction's, and capacitors can at the charging state draw as...
