Re: [Paparazzi-devel] [PPRZLINK] Code generation for receiving messages

[Gautier Hattenberger]

Hello,

PPRZLINK is generating both sending and reading macros and functions.
The reading macros are at the end of the file and they have the form:

DL_<MSG_NAME>_<field_name>(payload)

So once you have extracted the payload part of the message (PPRZ_DATA in 
http://wiki.paparazziuav.org/wiki/Messages_Format), you give this buffer 
to the macro corresponding to the field you want to read and it returns 
the value with correct type.
