Serial.print stops working after sleep(duration)? #3
Description
Hi,
I made some basic changes to timedWakeup.ino and I noticed that after sleeping for 1 second, the serial/usb are turned off and don't turn back on. When you run this, it should stop after the first loop and the print statements and blinking will stop. Anyway to get a full wakeup after PM.Sleep(1000)?
I am running the 2.02 version of the 101 library
#include <Power.h>
volatile int x = 0;
void setup() {
pinMode(LED_BUILTIN, OUTPUT);
Serial.begin(9600);
Serial.println("SEtup");
}
void loop() {
for(int i = 0; i < 5; i++)
{
digitalWrite(LED_BUILTIN, HIGH);
delay(500);
digitalWrite(LED_BUILTIN, LOW);
delay(500);
Serial.println("loop ");
Serial.println(i);
}
Serial.println("full loop ");
Serial.println(x);
x++;
Serial.flush();
PM.sleep(1000);
}
