SAMD20E18A UART (No ASF)
On the SAMD20; yes. The SERCOM units only have one NVIC line each. If you enable more than one interrupt for the SERCOM, you need to check the INTFLAG register to see winch...

SAME54 using SERCOM5 for SPI not working
In a project where I needed several separate CAN bus interfaces, i found using an extra SAMC21 was cheaper than using dedicated CAN controller chips.

ATSAME53J20A USB Composite Device and USB Vendor/Product ID and External QSPI NOR Flash SAM E54 Xplained
- No special VID/PID needed. Advertised capacity should be in the MSC descriptor. - You need to add+modify quite a lot of code to use anything but internal SRAM for block storage...

SAML11 how to run at 32MHz?
Most (if not all?) SAM controllers have built-in PLLs to synthesize a wide range of clock frequencies. Some can even run without a reference clock. Look into that. awneil wrote:...

ATSAME5x series Ethernet
It seems this issue has been fixed in rev D silicon.   Looking through the datasheet and errata, I can't figure out when revision D silicon was introduced. The best I can do...

ISRs in other source C files
I find it fascinating how the libraries obfuscates the real operation of the interrupt controller, making you jump through so many hoops to get things working the way you want....

UC3C2: DAC for internal routing to ADC does not exist. ??
The smallest UC3C has only one DACIFB implemented while the medium and large ones has both. I'm not sure what you'd get if you tried to use the DAC1_int signal, but it's not...

Problem in programing with atmel studio
I'm not saying you need the JTAGICE3 for the UC3-A3 XPlained. I just described how I do stuff. - For software real-time debugging, I'm using the JTAGICE3. - For USB in-system...

ADCIFA Window Monitor on Sequencer 1
The window monitor shouldn't care where the sample came from. It's job is to monitor it's assigned result register. There is nothing about this in the errata.   You confirmed...

ADCIFA Window Monitor on Sequencer 1
Are you sure the output from sequencer 1 is going into result register #8 ? I don't remember how the result registers work in dual sequencer mode, and the data-sheet isn't very...
