Cannot Wake SAMD21 with EXTINT
There is a "Schematic Checklist" in the data sheet. If the chip gets hot just from powering it it must be some very basic problem (like connecting VDDCORE to the supply). You can...

SAMD21 USART TX at PA24
Works for me, tested on a SAMD21 xPlained Pro. #include "sam.h" int main(void) { PM->APBCMASK.bit.SERCOM3_ = 1; GCLK->CLKCTRL.reg = GCLK_CLKCTRL_ID(...

ATSAMV71 Xplained Ultra I2C peripheral Issue
It's not completely obvious for me where you in each case connect to the I2C signals. TWIHS0 I expect is on PA03 and PA04 which is on the I2C pins on both EXT1 and EXT2, is...

SAM L10 I2C Slave
Did you try the available callbacks? This is from the user guide: The tx pending callback is invoked when a master device requests data from a slave device via sending slave...

SAML11 pulse width (and period) capture using timer module
Yes 16-bit mode has worked for me. The event is the only "signal" needed, I assume all the edge detection needed is done in the TC as hinted to here (about the asynchronous event...

It is possible create 8 pwm with single activation on SAMD21G17
Fixed period but also the same duty cycle on every output? TCC0 can be used for that. The waveform extension OTMX setting can be used to get the compare channel 0 on every output...

Setting TC2 compare capture value for SAMD11C
  TC2->COUNT16.CC0.reg = 45828;This I would have to write as TC2->COUNT16.CC[0].reg = 45828; GCLK_CLKCTRL_ID(GCLK_CLKCTRL_ID_TC1_TC2)GCLK_CLKCTRL_ID_TC1_TC2 is...
