Question about PDCA and HMATRIX arbitration
mtwieg wrote:So I want two PDCA channels to access the SRAM at the same time. Will these two channels conflict with each other, or with other operations that use the SRAM? They...

How can I get my AT32UCL064 I/O pin to source 3.0V?
I haven't looked at the data sheet for that particular flavor of AVR32 but I would be greatly surprised if Atmel would recommend powering anything other than the core with the 1....

umm... malloc fail :(
Under the hood the UC3 is a modified Harvard Architecture. The flash and RAM live in the same address space although at different and non overlapping address ranges obviously....

Mega 32 compiler errors
Also, wrong forum. This should be moved to the 8 bit forum.

Stabilizing digi pots
I'll go out on a limb here and guess the op has the 3 pot leads floating when making the ohmeter readings and leakage currents are charging stray (internal?) capacitance that is...

Corrupt EEPROM values....External Reset???
Wrong forum, this one is for 32 bit devices. Can a moderator move this to the 8 bit forum? PS: Leaving the reset pin floating is always a bad idea.

I2C PDCA
You need at most two PDCA channels; one for transmit and another one for receive. The number of slave devices on the bus does not factor in to the number of PDCA channels.

Register names in AVR studio 5
You (OP) realize that the peripheral control registers are just plain old memory mapped locations in the AVR32 address space, right? There are no predefined magic names that the...

DC motor speed controllability range, speed/torque vs PWM
If flutter is an issue for your application be aware that plain vanilla DC brush motors can have significant torque ripple. Adding inertia can mitigate this but may make speed...

Using the T/C module on UC3A0512
I think tables 31-3 and 31-4 on page 654 of the datasheet make it pretty clear.
