Hi there guys!
I am struggling with measuring the temperature witihin the loop function. What I tried to do is to call “measureTemperature()” function inside switch case “DEVICE_STATE_SEND”, but it seemed not to measure temperatures. It only works when i use it within the “setup()” function. So I came up with the idea that in case to measure temperature in every step, I will reset either LoraWan or the CubeCell board using “CySoftwareReset();” or “void(* resetFunc) (void) = 0;” after "LoraWan.sleep(), but the board didnt seem to get into sleep at all, what It did is just keep resetting no matter the sleep cycle. Do you have any idea how can i manage it to work? My code looks like this:
DallasSensor.ino:
//
// First we include the libraries
#include “OneWire.h”
#include “DallasTemperature.h”
//
// Data wire is plugged into pin 2 on the Arduino
#define ONE_WIRE_BUS GPIO1
//
// Setup a oneWire instance to communicate with any OneWire devices
// (not just Maxim/Dallas temperature ICs)
OneWire oneWire(ONE_WIRE_BUS);
//
// Pass our oneWire reference to Dallas Temperature.
DallasTemperature sensors(&oneWire);
/********************************************************************/
void setupTemperatureSensor(void)
{
// Turn on voltage supply on temperature sensor
pinMode(Vext, OUTPUT);
digitalWrite(Vext, LOW);
delay(500);
// Start up the library
sensors.begin();
}
void measureTemperature(void)
{
// call sensors.requestTemperatures() to issue a global temperature
// request to all devices on the bus
Serial.print(" Requesting temperatures…");
sensors.requestTemperatures(); // Send the command to get temperature readings
Serial.println(“DONE”);
// You can have more than one DS18B20 on the same bus.
// 0 refers to the first IC on the wire
Serial.print(sensors.getTempCByIndex(0));
Serial.print(",");
Serial.println(sensors.getTempCByIndex(1));
// delay(1000);
}
