Clients MAY log/display a suitable message. * * API clients should NOT attempt any communication if they can't handle the returned API MAJOR VERSION. * * API clients SHOULD attempt communication if the API MINOR VERSION has increased from the time * the API client was written and handle command failures gracefully. Clients MAY disable * functionality that depends on the commands while still leaving other functionality intact. * that the newer API version may cause problems before using API commands that change FC state. * * It is for this reason that each MSP command should be specific as possible, such that changes * to commands break as little functionality as possible. * * API client authors MAY use a compatibility matrix/table when determining if they can support * a given command from a given flight controller at a given api version level. * * Developers MUST NOT create new MSP commands that do more than one thing. * * Failure to follow these guidelines will likely invoke the wrath of developers trying to write tools * that use the API and the users of those tools. */ #pragma once /* Protocol numbers used both by the wire format, config system, and field setters. */ #define MSP_PROTOCOL_VERSION 0 #define API_VERSION_MAJOR 1 #define API_VERSION_MINOR 42 // for compatibility with DJI OSD #define API_VERSION_LENGTH 2 #define MULTIWII_IDENTIFIER "MWII"; #define BASEFLIGHT_IDENTIFIER "BAFL"; #define BETAFLIGHT_IDENTIFIER "BTFL" #define CLEANFLIGHT_IDENTIFIER "CLFL" #define INAV_IDENTIFIER "INAV" #define RACEFLIGHT_IDENTIFIER "RCFL" #define ARDUPILOT_IDENTIFIER "ARDU" #define FLIGHT_CONTROLLER_IDENTIFIER_LENGTH 4 #define FLIGHT_CONTROLLER_VERSION_LENGTH 3 #define FLIGHT_CONTROLLER_VERSION_MASK 0xFFF #define BOARD_IDENTIFIER_LENGTH 4 // 4 UPPER CASE alpha numeric characters that identify the board being used. #define BOARD_HARDWARE_REVISION_LENGTH 2 // These are baseflight specific flags but they are useless now since MW 2.3 uses the upper 4 bits for the navigation version. #define CAP_PLATFORM_32BIT ((uint32_t)1 << 31) #define CAP_BASEFLIGHT_CONFIG ((uint32_t)1 << 30) // MW 2.3 stores NAVI_VERSION in the top 4 bits of the capability mask. #define CAP_NAVI_VERSION_BIT_4_MSB ((uint32_t)1 << 31) #define CAP_NAVI_VERSION_BIT_3 ((uint32_t)1 << 30) #define CAP_NAVI_VERSION_BIT_2 ((uint32_t)1 << 29) #define CAP_NAVI_VERSION_BIT_1_LSB ((uint32_t)1 << 28) #define CAP_DYNBALANCE ((uint32_t)1 << 2) #define CAP_FLAPS ((uint32_t)1 << 3) #define CAP_NAVCAP ((uint32_t)1 << 4) #define CAP_EXTAUX ((uint32_t)1 << 5) #define MSP_API_VERSION 1 //out message #define MSP_FC_VARIANT 2 //out message #define MSP_FC_VERSION 3 //out message #define MSP_BOARD_INFO 4 //out message #define MSP_BUILD_INFO 5 //out message #define MSP_NAME 10 //out message Returns user set board name - betaflight #define MSP_SET_NAME 11 //in message Sets board name - betaflight // // MSP commands for Cleanflight original features // #define MSP_BATTERY_CONFIG 32 #define MSP_SET_BATTERY_CONFIG 33 #define MSP_MODE_RANGES 34 //out message Returns all mode ranges #define MSP_SET_MODE_RANGE 35 //in message Sets a single mode range #define MSP_FEATURE_CONFIG 36 #define MSP_SET_FEATURE_CONFIG 37 #define MSP_BOARD_ALIGNMENT_CONFIG 38 #define MSP_SET_BOARD_ALIGNMENT_CONFIG 39 #define MSP_CURRENT_METER_CONFIG 40 #define MSP_SET_CURRENT_METER_CONFIG 41 #define MSP_MIXER_CONFIG 42 #define MSP_SET_MIXER_CONFIG 43 #define MSP_RX_CONFIG 44 #define MSP_SET_RX_CONFIG 45 #define MSP_LED_COLORS 46 #define MSP_SET_LED_COLORS 47 #define MSP_LED_STRIP_CONFIG 48 #define MSP_SET_LED_STRIP_CONFIG 49 #define MSP_RSSI_CONFIG 50 #define MSP_SET_RSSI_CONFIG 51 #define MSP_ADJUSTMENT_RANGES 52 #define MSP_SET_ADJUSTMENT_RANGE 53 // private - only to be used by the configurator, the commands are likely to change #define MSP_CF_SERIAL_CONFIG 54 #define MSP_SET_CF_SERIAL_CONFIG 55 #define MSP_VOLTAGE_METER_CONFIG 56 #define MSP_SET_VOLTAGE_METER_CONFIG 57 #define MSP_SONAR_ALTITUDE 58 //out message get sonar altitude [cm] #define MSP_PID_CONTROLLER 59 #define MSP_SET_PID_CONTROLLER 60 #define MSP_ARMING_CONFIG 61 #define MSP_SET_ARMING_CONFIG 62 // // Baseflight MSP commands (if enabled they exist in Cleanflight) // #define MSP_RX_MAP 64 //out message get channel map (also returns number of channels total) #define MSP_SET_RX_MAP 65 //in message set rx map, numchannels to set comes from MSP_RX_MAP // DEPRECATED - DO NOT USE "MSP_BF_CONFIG" and MSP_SET_BF_CONFIG.
