XMEGA and TWI problem Well then you have two problems, first you simply cannot use internal pull-ups for I2C - your uC's internal pull up resistor values are stated in the datasheet to be 25k (see page...

XMEGA and TWI problem Haven't really looked at your code yet, but first things first, hardware; have you got external pull-ups on SDA and SCL? Typical values are 4k7.

XMEGA A1U Xplained Pro PC2 pulled high? Hi Jim,
I'm 99% sure that it's not being pulled up via software (the 1% unsure-ness is whether or not the EDBG is sending some sort of command or something instructing it...

Visual Studio and Atmel Studio Temp File Explosion Before going through the hassle of removing and reinstalling AS7 and VS, I'd suggest you check for updates on both. I know a little while ago there was an update for either VS or...

I've never used RS485 myself so excuse me if this is a bad idea, but how about you simply have 1 IO, configured as an input on your master, and outputs on your slaves. You use a...
