Hi, I noticed that if I put the microcontroller to sleep immediately following a println, only garbage will appear on the Serial Monitor. With a delay(1) inserted, things work. Could it be that the "wait then write" strategy in putchar has a drawback here, as the controller goes to sleep before the serial transmission is complete?
