Detailed Description

Function Documentation

void mbed_die ( void  )

Cause the mbed to flash the BLOD (Blue LEDs Of Death) sequence.

void mbed_error_printf ( const char *  format,
  ... 
)

Print out an error message.

This is typically called when handling a crash.

Note
Synchronization level: Interrupt safe
This uses an internal 128-byte buffer to format the string, so the output may be truncated. If you need to write a potentially long string, use mbed_error_puts.
Parameters
formatC string that contains data stream to be printed. Code snippets below show valid format.
1 mbed_error_printf("Failed: %s, file: %s, line %d \n", expr, file, line);
void mbed_error_puts ( const char *  str)

Print out an error message.

This is typically called when handling a crash.

Unlike mbed_error_printf, there is no limit to the maximum output length. Unlike standard puts, but like standard fputs, this does not append a '
' character.

Note
Synchronization level: Interrupt safe
Parameters
strC string that contains data stream to be printed.
void mbed_error_vfprintf ( const char *  format,
va_list  arg 
)
Deprecated:
Renamed to mbed_error_vprintf to match functionality
void mbed_error_vprintf ( const char *  format,
va_list  arg 
)

Print out an error message.

Similar to mbed_error_printf but uses a va_list.

Note
Synchronization level: Interrupt safe
Parameters
formatC string that contains data stream to be printed.
argVariable arguments list
void mbed_mac_address ( char *  mac)

This returns a unique 6-byte MAC address, based on the interface UID If the interface is not present, it returns a default fixed MAC address (00:02:F7:F0:00:00)

This is a weak function that can be overwritten if you want to provide your own mechanism to provide a MAC address.

Parameters
macA 6-byte array to write the MAC address
