Please, could some help me with this compiling error?

Former Member

I do not understand this error: 

 

ebl_RTC_Logging_BMP085.ino: In function 'void loop()':

ebl_RTC_Logging_BMP085:158: error: expected unqualified-id before string constant

 

 

156 //Create Data string for storing to SD card

157 //We will use CSV Format 

158  String dataString = "(id) + ", " + String(Temperature_degF)+ ", " + String(Pressure_inHG) + ", " + String(atm) + ", " + String(Altitude_Ft) + ";

    At a glance, the problem seems to be a little mix up with where " is used in relation to concatination of string literals and variables. Put simply, the " need to be going around anything that doesn't change, such as the commas used in CSV format. Correcting that you should get something like

    String dataString = id + ", " + String(Temperature_degF)+ ", " + String(Pressure_inHG) + ", " + String(atm) + ", " + String(Altitude_Ft);

     

    You'll just need to adjust that to match the format you need for the CSV file, such as line endings, appropriate use of white space (http://en.wikipedia.org/wiki/Comma-separated_values)

     

    This might help with your issue, give it a go and let us know! image

    I think John is correct that your quote marks are mixed up, and what you

    think is inside the quotes is actually outside them, and vice versa.

     

    As a general suggestion, when you get a mysterious error message from

    something complicated like this, try making it gradually simpler and simpler.

    In the process, either the error message will go away at some point,

    and then look closely at what you just changed.  Or the error message

    will still remain on a much simpler statement, in which case the cause

    will be much more obvious.
