I need help with getting my gps and bmp085 sensor working with arduino

I have been working with this for a couple of days and i can not get this program working. It keeps saying i have and error compiling the program.

With such long code it would make it more readable if you were to enclose it within "CODE" tags. You can go back and edit your existing post.

[adafruit_support_bill]

It keeps saying i have and error compiling the program

It would help if you posted the text of the error too.

[DatBoyEvV]

Sorry about that

here is the error:

Code: Select all


Error compiling
In file included from sketch_apr24a.cpp:1:
C:\Users\EVV\Desktop\arduino-1.0\libraries\NewSoftSerial/NewSoftSerial.h:71: error: conflicting return type specified for 'virtual void NewSoftSerial::write(uint8_t)'
C:\Users\EVV\Desktop\arduino-1.0\hardware\arduino\cores\arduino/Print.h:48: error:   overriding 'virtual size_t Print::write(uint8_t)'



[adafruit_support_bill]

Looks like you are using the Arduino 1.0 IDE. Starting with 1.0, the functionality of NewSoftSerial has been integrated as "SoftwareSerial". You should replace your "#include <NewSoftSerial.h>" with "#include <SoftwareSerial.h>". You should also remove the NewSoftSerial folder from your libraries folder to avoid conflicts.

Another problem you are likely to encounter has to do with: "#include <Adafruit_BMP085.h> ". Unless you renamed it when you installed it, the name of the file is just "BMP085.h ".

[DatBoyEvV]

I changed the " #include <NewSoftSerial.h>" to " #include <SoftwareSerial.h>" and took the NewSoftserial library out and now im getting this error

Code: Select all


'gpsSerial' was not declared in this scope

Did you change the type of gpsSerial from NewSoftSerial to SoftwareSerial?

No, it looks like you deleted the declaration entirely. In your previous posted code you had it declared as:

Code: Select all

    NewSoftSerial gpsSerial(2, 3);

In the last post there is no declaration at all. You need to add it back in as:

Code: Select all

    SoftwareSerial gpsSerial(2, 3);
