I'm currently using SAMD20G18A on a custom board to monitor some voltages via the ADC. I want to transmit the temperatures collected using USART to the PC, to be displayed on putty or teraterm. So I decided to use a simple hello world program using ASF 3.36 which has a Standard serial I/O driver. Since PBCKCODE is not letting me add the code, please find attached main.c
Do I need to add something else to get it working? When I try to single step the printf, it just skips and moves to the delay.
