Detailed Description

User-configurable stack configuration macros and defaults.

Connect stack provides various interfaces to apply configuration:

  • APIs to change configuration run-time
  • Manufacturing tokens to change configuration during device flashing
  • Macros to change configuration at compile-time

The compile time configuration macros and their default values are listed here.

The default values are always chosen to make it usable for most applications, but in some cases, you might need to change it. The recommended way is to either define the macro you need to change in the compilation command (e.g. gcc -D) or you by manipulating the configuration options in the configurator GUI.

See ember-configuration-defaults.h for source code.
