I would like to have Debug Out to SWD SWO, printf would be best.
Can I add some module in AtmelStudio to initialize SWO and have printf or similar?
Connecting some 3,3 Volt USB Serial to SWO and have the Output in some Terminal would be most easy.
Think have to setup SWO serial parameters, baud, bits, etc for.
Controller is SAMR21 (SAMD21 Family, Cortex M0 ?).
