Error on using OneWire library
-
Dear All,
I started to use Sony Spresense instead of Arduino.
I am trying to use OneWire library for DS18S20 temperature
sensor.
It returns multiple errors.error: no matching function for call to 'OneWire::OneWire
candidate: constexpr OneWire::OneWire(const OneWire&)
exit status 1
void value not ignored as it ought to beEtc.
Also, please can anyone to show me an example for defining digital pins.
For example D05
is this correct?
OneWire ds(digitalPinToInterrupt (05), connect, RISING);I appreciate you kind concerns about these issues.
Thank you

Hi @niro
It would be good if you could share both your sketch and information on where you got the library.
But anyway. The pins for the Arudino IDE used in Spresense are defined in (using Ubuntu):
~/.arduino15/packages/SPRESENSE/hardware/spresense/1.5.1/variants/spresense/pins_arduino.hThe names lookes like this:

Thank you very much for your reply.
I would like to share the sketch. I downloaded the library from Arduino Manage libraries.
This is my sketch,#include <OneWire.h> //int DS18S20_Pin; int DS18S20_Pin = attachInterrupt (digitalPinToInterrupt (05), connect, RISING); //DS18S20 Signal pin on //x = digitalPinToInterrupt (D07); //attachInterrupt (x, ISR, mode); //int DS18S20_Pin = PIN_D07; //DS18S20_Pin.attach(PIN_D07); //Temperature chip i/o OneWire ds(digitalPinToInterrupt (05), connect, RISING); // on digital pin 2 void setup(void) { Serial.begin(9600); } void loop(void) { float temperature = getTemp(); Serial.println(temperature); delay(1000); //just here to slow down the output so it is easier to read } float getTemp(){ //returns the temperature from one DS18S20 in DEG Celsius byte data[12]; byte addr[8]; if ( !ds.search(addr)) { //no more sensors on chain, reset search ds.reset_search(); return -1000; } if ( OneWire::crc8( addr, 7) != addr[7]) { Serial.println("CRC is not valid!"); return -1000; } if ( addr[0] != 0x10 && addr[0] != 0x28) { Serial.print("Device is not recognized"); return -1000; } ds.reset(); ds.select(addr); ds.write(0x44,1); // start conversion, with parasite power on at the end byte present = ds.reset(); ds.select(addr); ds.write(0xBE); // Read Scratchpad for (int i = 0; i < 9; i++) { // we need 9 bytes data[i] = ds.read(); } ds.reset_search(); byte MSB = data[1]; byte LSB = data[0]; float tempRead = ((MSB << 8) | LSB); //using two's compliment float TemperatureSum = tempRead / 16; return TemperatureSum; }This is simple sketch given by DFRobot temperature sensor.

I appreciate your kind support.
Thank you!
