Configure RTX

The file RTX_Conf_CM.c is used to define the configuration parameters of CMSIS-RTOS RTX. This file must be part of every project that is using the CMSIS-RTOS RTX kernel.

The configuration file uses Configuration Wizard Annotations. Refer to Pack - Configuration Wizard Annotations for details. Depending on the development tool that is used, this might lead to a more user friendly graphical representation of the settings. The following is a screenshot of the same configuration file using µVision's Configuration Wizard view:
