UC3B ADC activating output driver?
Must be a hardware problem on your custom board then. Can you show us the schematic?

UC3B ADC activating output driver?
Ok. So no problem with adc_start(). Right after adc_start(AVR32_ADC); add a line: U32 oder = AVR32_GPIO.port[0].oder; The value of oder will show you which output drivers are...

UC3B ADC activating output driver?
What value are you passing to adc_start()?

Bit Feilds
While bit fields are always refered to as "use at your own risk" (i.e implementation defined) I have yet to see a compiler that didn't order the bits according to the endieness of...

AT32UC3A ADC Internal triggers - how?
Interesting. It seems Atmel omitted a vital section from the UC3A datasheet. The UC3B data sheet has an additional section in the ADC chapter titled "Module Configuration" which...

UC3-A3 USART Example low voltage problem
Are you using a 10x probe and the scope thinks it has a 1x probe?

Plz explain more on the two diodes in the below schematic
For those arguing about AND and OR: /A+/B = /(A*B) where: "/" = NOT "+" = OR "*" = AND Google "DeMorgan's theorem"

Cycle Counter not working?
I tried this on a UC3B164 application I have here. The clocks were configured as: MCLK - PLL0 @ 60 MHz HSB - 60 MHz PBA - 15 MHz PBB - 60 MHz unsigned long cycleCount =...

Using multiple IRQ and PDCA channels
Are you using both RX and TX of the TWI? If so, you need a separate PDCA channel for each.

Can't get 5v Vtarget on STK600 - UC3C
Just a wild guess but maybe AVR studio is trying to keep you from blowing up your MCU since the UC3 is 3.3V part? Maybe not such a wild guess after all. According to: http://www....

AT32UC3C1512C Endianness
What led you to believe that it's little endian? UC3s are in fact big endian.

LD.W instruction syntax
It would be nice if the documentation included an example of each instruction variant. They do show examples on some of the instructions in the manual, but not all. I've been...
