Default system features

The default configuration includes those major features. They are all initialized by sys_start() at the startup of the application.

Library Reference

Read more about board specific functionality in the Maple-ESP32 module documentation in the Library Reference.

Memory usage

Below is the memory usage of two applications:

  • The minimal-configuration application is configured to only include the bare minimum of functionality for the low level kernel to run. That is, the thread scheduler and system tick.
  • The default-configuration application is built with the default configuration, including a lot more functionality. See the list of Default system features above for a summary.
