FC CMS
Recent releases of Betaflight, Cleanflight and iNav flight controller firmware have a Configuration Menu System (CMS) that allow access to many of the configurable items.
FC firmware must be built with CMS and USE_MSP_DISPLAYPORT or equivalent options, and corresponding features should be turned on in configuration if they are controlled via features.
Many already have this enabled if there are enough resources on the FC. Most F3 F4 and higher have this enabled. If enabled and there is an onboard OSD of the FC, OSD in FC configuration settings should be disabled
BETAFLIGHT, CLEANFLIGHT and iNAV options in releases of MWOSD from November 2017 onwards have this enabled by default.
To test you can enter MWOSD menu and find the one titled FC configuration. Follow the instructions on screen and if FC configuration is available you the MWOSD menu will close and you will enter the FC CMS
You can also enter directly from TX by using:MID THROTTLE + FULL PITCH + LEFT YAW
