cancel your D09 projects, maybe others
  I'll be deliberately short on details, but I'll say prices will go up soon, in particular for the D09, just verify the current price at your distributor. For the D09D14...

Where are VREF.BGOUTEN (1V bandgap voltage reference output enable) and VREF.TSEN (temperature sensor enable)?
The D09 (D10/D11) datasheet on page 150, section 16.6.12.1 ("User Control of the Voltage Reference System"), says:   To enable the temperature sensor, write a one the...

SPI on 24MHz (D09)
Hi. I need an SPI running at 24MHz (on the D09, but the SPi is the same across many devices, ex D20). That should be possible in Slave mode, using an external 24MHz clock. It...

Trouble setting LIN baudrate (on SAMD10, no ASF)
I'm having trouble setting up the UART/USART on the D10 (Xmini). The goal is to configure the UART as a LIN slave at 19.2kbps, on pins 24+25.   When I change the value for...

Move Atmel Studio project to Keil
I'm using a 16k D10, which requires no license in Keil, and my application is GCC-application based (it only includes "sam.h").   As I find the lack of live watches jarring...

Which devices support live watches
This is my first venture into Cortex M0. I am developing on the D10 mini xplained. I came from 8-bitters that had live watches: I could see variables change in response to events...

high RAM usage / memory alignment / packing
I get "region `RAM' overflowed by 712 bytes" on a D10. I have the following arrays:   // the arrays u8 a[288]; u16 b[288]; u16 c[288]; u16 d[16]; // note: these arrays...

Using the internal oscillator (not ASF)
I found this post regarding the clocks (for the D21, but probably applicable to the D09/D10/D11):      http://borkedlabs.com/2014/08/21...   Quite clear and...

Capture pulse width & duration
I need to use TC2 as a capture of both period and duration on PA05 (8b mode, maximum period). It also needs to generate an interrupt on overflow.   What I know thus far: -...
