List of Preprocessor Build Settings#
This section provides the list of preprocessor macros that can be edited in the build settings and are available with the WiSeConnect™ SDK v3.x with the SiWx91x™ and EFR32™ hosts.
Some macros shown in the preprocessor build settings window are not listed below if they cannot be modified by the user.
Macros are listed in alphabetical order.
