Detailed Description

This example shows a basic setup for any MIP-enabled MicroStrain device to demonstrate how to get and print device information using C++. This is not an exhaustive example of all settings for those devices. If this example does not meet your specific setup needs, please consult the MIP SDK API documentation for the proper commands.

Function Documentation

logCallback()

static void logCallback ( void *  _user, const microstrain_log_level  _level, const char *  _format, va_list  _args  )

static

Processes and formats log messages from the MIP SDK based on severity level. Routes messages to appropriate output streams - errors and fatal messages go to stderr while other levels go to stdout. Each message is prefixed with its severity level name.

Parameters

_user	Pointer to user data (unused in this implementation)
_level	Log message severity level from microstrain_log_level enum
_format	Printf-style format string for the message
_args	Variable argument list containing message parameters

initializeDevice()

static void initializeDevice ( mip::Interface &  _device )

static

Performs a complete device initialization sequence:

1. Verifies device communication with a ping command
2. Sets the device to idle mode to ensure reliable configuration
3. Queries and displays detailed device information

Parameters

_device

Reference to a MIP device interface to initialize

terminate() [1/2]

static void terminate ( microstrain::Connection *  _connection, const char *  _message, const bool  _successful  )

static

Handles graceful shutdown when errors occur:

• Outputs provided error message
• Closes device connection if open
• Exits with appropriate status code

Parameters

_connection	Pointer to the device connection to close
_message	Error message to display
_successful	Whether termination is due to success or failure

terminate() [2/2]

static void terminate ( mip::Interface &  _device, const mip::CmdResult  _cmdResult, const char *  _format,   ...  )

static

Handles command failure scenarios:

• Formats and displays an error message with command result
• Closes device connection
• Exits with failure status

Parameters

_device	MIP device interface for the command that failed
_cmdResult	Result code from a failed command
_format	Printf-style format string for error message
...	Variable arguments for format string

Variable Documentation

PORT_NAME

constexpr const char* PORT_NAME = "/dev/ttyACM0"

staticconstexpr

BAUDRATE

constexpr uint32_t BAUDRATE = 115200

staticconstexpr

Note

For native serial connections this needs to be 115200 due to the device default settings command Use mip::commands_base::*CommSpeed() or mip::commands_3dm::*UartBaudrate() to write and save the baudrate on the device
