ByteToFloat

[matthijsberg]

Hi Paul,

I tried compiling and example 7 this evening, but I run into those errors:

{
    "resource": "/Users/matthijsvandenberg/Documents/PlatformIO/Projects/AirQual Plafond/.pio/libdeps/d1_mini/sps30/src/sps30.h",
    "owner": "cpp",
    "severity": 8,
    "message": "conflicting declaration 'typedef union ByteToFloat ByteToFloat'",
    "startLineNumber": 329,
    "startColumn": 3,
    "endLineNumber": 329,
    "endColumn": 3
}

and

{
    "resource": "/Users/<naam>/Documents/PlatformIO/Projects/AirQual Plafond/lib/scd30/src/paulvha_SCD30.h",
    "owner": "cpp",
    "severity": 8,
    "message": "'ByteToFloat' has a previous declaration as 'typedef union ByteToFloat ByteToFloat'",
    "startLineNumber": 110,
    "startColumn": 3,
    "endLineNumber": 110,
    "endColumn": 3
}

I try this with PlatformIO in VSCode. Any idea's? Google comes up empty. Is this an old version of something? Bit of a noob as you know. :-(

Thnx.

hi Matthijs

The issue is because you have ByteToFloat double declared in your project. The complete project folder is compiled and it finds 2 times a declaration with the same name (does not matter whether the declaration is the same..)

You havea file :

Plafond/.pio/libdeps/d1_mini/sps30/src/sps30.h",

And you have a different file:

Plafond/lib/scd30/src/paulvha_SCD30.h

Indeed what I have done is use code, previous developed for SPS30, into my SCD30 library. Don't like to rewrite the same code twice. I did not consider anyone would use both SPS30 and SCD30 at the same time. I have just made a small change and uploaded a new version of the SCD30 ( no change to SPS30) to prevent this error happening again.

regards, Paul

update, compiled the example on Arduino IDE and works instantly. Must be something specific to VS Code or PIO of the person behind the keyboard.
