See ember-debug.h for source code.

Macro Definition Documentation

#define BASIC_DEBUG   1
#define emberDebugInit ( port ) do {} while (false)

This function is obsolete and no longer required to initialize the debug system.

Parameters
port Ignored because the port used for debug communication is automatically determined for each platform.
#define FULL_DEBUG   2
#define NO_DEBUG   0

Function Documentation

void emberDebugAssert ( PGM_P filename,
int linenumber
)

Prints the filename and line number to the debug serial port.

Parameters
filename The name of the file where the assert occurred.
linenumber The line number in the file where the assert occurred.
void emberDebugBinaryPrintf ( PGM_P formatString,
...
)

Prints binary data to the debug channel.

This function does not use the normal printf format conventions. To print text debug messages, use emberDebugPrintf() . The format string must contain only these conversion specification characters:

  • B - uint8_t value.
  • W - uint16_t value, printed least significant byte first.
  • D - uint32_t value, printed least significant byte first.
  • F - pointer to null terminated string in Flash (PGM_P).
  • xxxp - pointer to RAM, length is xxx (max 255).
  • lp - pointer to RAM, length is uint8_t argument.
  • xxxf - pointer to Flash (PGM_P), length is xxx (max 255).
  • lf - pointer to Flash (PGM_P), length is uint8_t argument.
  • b - EmberMessageBuffer.

Examples:

1 emberDebugBinaryPrintf("BWD", status, panId, channelMask);
2 emberDebugBinaryPrintf("F8p", "string example", eui64);
3 emberDebugBinaryPrintf("lp64fb", length, bytes, dataTable, buffer);
Parameters
formatString A string of conversion specification characters describing the arguments to be printed.
... The arguments to be printed.
void emberDebugError ( EmberStatus code )

Prints an EmberStatus return code to the serial port.

Parameters
code The EmberStatus code to print.
void emberDebugMemoryDump ( uint8_t * start,
uint8_t * end
)

Prints the contents of RAM to the debug serial port.

Parameters
start The start address of the block of RAM to dump.
end The end address of the block of RAM to dump (address of the last byte).
void emberDebugPrintf ( PGM_P formatString,
...
)

Prints text debug messages.

Parameters
formatString Takes the following:
%% Percent sign
%c Single-byte char
%s RAM string
%p Flash string (does not follow the printf standard)
%u Two-byte unsigned decimal
%d Two-byte signed decimal
%x, %%2x, %%4x 1-, 2-, 4-byte hex value (always 0 padded; does not follow the printf standard)
bool emberDebugReportOff ( void )

Turns off all debug output.

Returns
The current state (true for on, false for off).
void emberDebugReportRestore ( bool state )

Restores the state of the debug output.

Parameters
state The state returned from emberDebugReportOff() . This is done so that debug output is not blindly turned on.
void emDebugSendVuartMessage ( uint8_t * buff,
uint8_t len
)

Sends VUART data out the debug channel.

Parameters
buff A pointer to the data to send.
len The length of the data to send.
