What does an inductor in series with VCC do?
Hi Everyone,   I've done some reading about how an inductor will resist changes in current as opposed to how a capacitor resists changes in voltage.   How does this help...

Does EDMA help this...
I asked about this before, but not using an XMEGA.  My goal is to monitor a port (8 signals) and if the pin has been low the entire time, turn off a LED, if it has been high...

Does anyone have an Atmel ICE plastic case from a dead one?
I ordered the pcb a long time back and wish I had ordered it with a case.  If anyone's Atmel ICE dies on them and they have an extra case, I'd love to have it.  Thanks!

What is the best way to accomplish this - fast pin sampling...
So what I want to do is make a small 8 channel logic probe.  I've already got a small buffered led, but it is useless for showing an intermediate state because they are...

Whcih AVR's have a real TWI and which don't?
I figured that the mega's typically had a real TWI since the atmega328 does.  I was a bit surprised to find that the atmega325a does not.  I thought that the USI was...

Reading VCC with the ADC...
I am using an atmega325A - if Reference selection bits are set to "AVCC with external capactor at AREF pin" and the mux is set to 1.1V (Vbg) - can you use the value to calculate...

ATMEGA325A returns 0xFF for device signature - but it is talking!?!
I hooked logic analyzer up and can see that 0xAC 0x53 0x00 0x00 were send - the third byte returned via MISO is 0x53:     But when the atmelice tries to query its...

Code that puts data in a specific section issues
This compiles with winavr I think and I'm trying to get it to work in AS7:   uint8_t logo[] __attribute__ ((section(".bitmaps")))= { DATA HERE }   The makefile has:...

FUSEBYTE4 programming problem...
My programmer uses PDI to program XMEGA fuses and it does it by first checking to see if the fuse needs to be changed, and if it does, it will write it, and then read it back to...

Xmega TWI trying with mojochan's code having problems...
Hi Everyone,   Using code form here:   https://github.com/mojo-chan/xme...   It gets hung up between "read4" and "read5".  WIF is never set.   Logic...

Why is _crc16_update being linked in twice?
Hi,   I can see it twice in the LSS/Size file, once at 0x340a and once at 0xb9a.  I've got two different modules using it.  Both call:   #include "util/crc16.h...

AS7 atsuo file is in odd directory structure .vs\projectname\v14\.atsuo
Hi,   Does anyone know how to go back to the old way where it just kept projectname.atsuo in the same directory as the .atsln file?   Thanks,   Alan
