many thanks for the answer
but this software in not functional on the mkrZero .
it is a part of the specification SAMD21.
indeed,i had to try this code but no signal on the output pin.
do you have a simple code functional for the mkrZERO .
i have few questions :

  1. how do you call the sercom3_handler
  2. how do you configure the pin sercom (PIO_SERCOM) for PB22 and PB23

Thanks .
