DebugPrint GCC

About

C library for debug printing with GCC.

Usage

Use the DBG_PRINTF_X macro for printing, where X is the debug level. These levels and their coloured outputs are as follows:

Level	Colour
Debug	Green
Trace	White
Warning	Yellow
Error	Red

Finally, you will need to implement the int debug_print_callback(char* debugMessage, unsigned int length). This callback function is called in the debug print functions so that the user can decide where to and how to print the debug messages.

See the debug_print.h file for more info.

Configuration

• Define DBG_PRINT_ENABLED to 1/0 enable/disable debug printing.
• Define DGB_PRINT_BUFFER_SIZE to set the debug print message buffer size.
• Define DBG_PRINT_ENABLE_TIMESTAMP to 1/0 to include/exclude timestamps in debug messages.
  • NOTE: You must implement time_t debug_print_get_timestamp(void) which returns the timestamp from the system.

Output

The colour of the output depends on the used debug level but message format stays the same.

The output format is [<filename>:<function name>():<line number>]: <message>. An example output would be: [main.c:main():13]: Initializing.
