GY-63 MS5611 interface with Arduino (Due)

Posted by Omair Khalid on June 9, 2014 at 12:36am

I am desperately in need of guidance for the interfacing of GY-63 MS5611 barometer with Arduino Due. I cannot even start the communication with Arduino.

Any help or guidance would be appreciated.

I will be extremely grateful for an urgent response!

Hi Omair,
"I cannot even start the communication with Arduino."
Can you successfully compile and upload a sketch? How have connected the gy-63? What code do you have so far?

  Thank you for your response.
  
  I have downloaded the "i2c scanner for arduino" which allows you to detect an i2c comm link. I am able to compile it but it says No Devices Found.
  
  I have setup the GY-63 MS5611 exactly as said by the datasheet here:
  http://www.meas-spec.com/downloads/MS5611-01BA03.pdf (Page 17)
  
  I have tried this much so far.

    Can you please be specific as to how you are powering your gy-63 and exactly what pins on your due you are using

      I am powering GY-63 by the 5V output pin on Arduino Due.
      
      i am using the SCL (Pin 21), SDA (Pin 20) on the Arduino Due to connect to SCL, SDA pins on GY-63. I am also using 10K pull up resistors for the SCL, SDA pins of GY-63.

        Have you connected PS high?
        
        Page 14:
        
        PS high (VDD) => I2C
        
        PS low (GND) => SPI

        Yes, I have done so.
        
        I have also tried connecting the CSB pin to high as well as low. No benefit.

        Hmmm... that seems to cover the basics.... I have a Due + GY-63 at the office - I will check for you tomorrow (approx 12 hrs)

        Thank you very much. I will be eagerly waiting for your response.

        Omair,
        
        I am glad you got it to work. Unfortunately I have not ever had to interface this sensor to the Due previously so I have no code on hand to share. I see there are a few Arduino libraries around for this sensor but I suspect none of them will compile directly for the Due. I just downloaded the FreeIMU library from:
        
        http://www.varesano.net/projects/hardware/FreeIMU#library
        
        and with a bit of tweaking, managed to compile both:
        
        libraries\MS561101BA\examples\MS561101BA_simple.pde
        
        libraries\MS561101BA\examples\MS561101BA_altitude.pde
        
        I am based at our head office today and do not have access to the Due or sensor to check if this was successful. As it is Friday today, I will not be back at the office until Monday but can check the code then.
        
        I have attached the altered FreeIMU files so you can have a go yourself
        
        MS561101BA.cpp
        
        MS561101BA.h

        Omair,
        
        I encountered the same issue you describe using a similar setup. It looks like there is a bug in the Wire library that is causing a problem with the Due. You can download the very latest master version of Arduino from:
        
        https://github.com/arduino/Arduino
        
        or just update Wire.cpp from here:
        
        https://github.com/bluesign2k/Arduino/blob/63f0ca06a8af7a223aacca8b...
        
        This fixes the problem for me.
