Svigote

Is there any way i can get a Library API for Code::Blocks instead of having to switch between my usual compiler and the stand alone Code::Blocks for arduino? Or a way to merge the stand alone with the official release?

thank you for your project. it's a pity there is no Linux version

Hello, I have some issues with latest CodeBlocks.

It doesn't build code that has been builded successfully in Arduino IDE.
Let me explain a bit my problem.
I have Anarduino MiniWireless and couple thermo sensors DS18B20 connected to it.
I'm trying compile and run default example "Multiple" from DallasTemperature Library.
I've added OneWire and DallasTemperature Library and it works with another code which uses only one termo sensor.
But I need more that one sensor so I decided check this "Multiple" example.

this is my code, a bit changed due to that fact that we need _define_ function before being used as it is explained on page 3 of this thread: http://forum.arduino.cc/index.php?topic=145397.30
Code: [Select]
#include <Arduino.h>

#include <OneWire.h>
#include <DallasTemperature.h>

// Data wire is plugged into port 10 on the Arduino
#define ONE_WIRE_BUS 10
#define TEMPERATURE_PRECISION 9

// 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);

// arrays to hold device addresses
DeviceAddress insideThermometer, outsideThermometer;

//my changes start ---------------------------------------------
//********************************
// function to print a device address

// function to print the temperature for a device
void printTemperature(DeviceAddress deviceAddress);

// function to print a device's resolution

// main function to print information about a device
void printData(DeviceAddress deviceAddress);

void setup(void)
{
  // start serial port
  Serial.begin(9600);

  // report parasite power requirements
  Serial.print("Parasite power is: ");
  if (sensors.isParasitePowerMode()) Serial.println("ON");

  // assign address manually.  the addresses below will beed to be changed

  // search() looks for the next device. Returns 1 if a new address has been
  // returned. A zero might mean that the bus is shorted, there are no devices,
  // or you have already retrieved all of them.  It might be a good idea to
  // check the CRC to make sure you didn't get garbage.  The order is
  // deterministic. You will always get the same devices in the same order
  //
  // Must be called before search()
  //oneWire.reset_search();
  // assigns the first address found to insideThermometer

Please advice.

I've just fixed this issue.

I had to add .cpp and .h library files into my project folder AND - add these files into project in CodeBlocks.
After that everything goes ok.

What a wonderful program. :)

Working with simple sketch all good, but as I get more ambitious...

I see this error...

Compiling: TSL230R_Light_Sensor.ino
Linking console executable: build\TSL230R_Light_Sensor_mini328.elf
Assembler messages:
Fatal error: redefinition of mcu type `atmega328p' to `atmega8'
Process terminated with status 1 (0 minute(s), 2 second(s))
0 error(s), 2 warning(s) (0 minute(s), 2 second(s))

All the labels and code invocations seem to make sense... I checked all I could see and "atmega328p" was being assigned to $MCU

Any ideas?

Randy
