Arduino UNO and serial monitor hangs.

[rajchips]

Hi,

It's working now...
Library examples are not correct. All probe assignment should be before "void setup(){"
See below for correct code...

//#include <OneWire.h>
#include <OWBus.h>
#include <OWBus/DS18B20.h>
#include <OWBus/DS2413.h>

#define ONE_WIRE_BUS 7 // Where 1W bus is connected to
OneWire oneWire(ONE_WIRE_BUS); // Initialize oneWire library
OWBus bus(&oneWire);
int count;

DS18B20 probe(bus, 0x282503E00200000B);
DS2413 led(bus, 0x3A34074E0000000A);
DS2413 fan2(bus, 0x3AF3E64D0000008F);

void setup() {
Serial.begin(9600);
delay(100);
count=1;
}

void loop() {
//Serial.println(probe.getTemperature());

if (probe.getTemperature()>=29){
led.setPIOA( false );
led.setPIOB( false );
fan2.setPIOB( true );
}

else{
led.setPIOA( true );
led.setPIOB( true );
fan2.setPIOB( false );
}

//Serial.println(fan2.readPIOs());
//Serial.println(fan2.getPIOB());

delay(500);

//count++;
//Serial.println(count);

bt_upload();

}

Hi, sorry for this late issue (I was busy by other stuffs that leave me away from git :) ).

Do you means it's hanging at the printf line ? If so, I think there is something broken in Serial code as I got the same issue with OneWireArduino lib and it seems something wrong about interruption management in Serial vs other stuffs.

Can you please try with only 1 probe ?

Hi, Arduino UNO hangs around 138 print loops with 3 probes attached. Arduino Mega256 hangs around 690 print loops with 3 probes attached. Arduino UNO hangs around 146 print loops with single probe DS18B20( however 3 device attached to bus). Arduino UNO, printing no probe DS18B20 then no hangs( however 3 device attached to bus)... I can do further testing for you if needed, please let me know. I have about 20 DS18b20 and 25 DS2413.

Ok, so I think there is a memory leak somewhere every time an object is created.
I didn't noticed it as I'm mostly using DeepSleep on my ESP which cause a full restart at every wakeup.
I'll investigate. Thanks for the report.

In addition, Arduinos have a very small memory so creating stack objects is probably not a good idea as well.
