Hello,
I’m trying to utilise the JeeLib.h library to hibernate a UNO to conserve battery power but am having some fundamental problems and have resorted to the original JeeLib Sketch example to start from basics.
Here is the sketch;;;
#include <JeeLib.h> // Low power functions library
int led_pin = 7;
ISR(WDT_vect) { Sleepy::watchdogEvent(); } // Setup the watchdog
void setup()
{
Serial.begin(9600, SERIAL_8N1); // Serial interface for for DEPTH data
Serial.println("\nUNO - Setup...."); pinMode(led_pin, OUTPUT);
} // end of setup
void loop()
{
// Turn the LED on and sleep for 5 seconds
digitalWrite(led_pin, HIGH);
Serial.println("\nLED On");
Sleepy::loseSomeTime(5000);
// Turn the LED off and sleep for 5 seconds
digitalWrite(led_pin, LOW);
Serial.println("\nLED Off");
Sleepy::loseSomeTime(5000);
}
When I run the sketch the LED turns on and off as expected but the output to the console looks like this
====

ad infinitum which is preventing me from adding checkpoints in my main program.
It is most likely a simple error on my part but I am unable to see it.
Any help much appreciated.
PS I need to hibernate the UNO for 15 minutes and if there is as an alternative method I might use I would appreciate some info.
Many thanks.
