Embedded diagnostic logger

Logging system for small microcontroller projects.

Usage

File: main.c

#include "log.h"
#include "uart.h" /* user develop library for serial uart */


LOG_MODULE_DEFINE(main); /* module name should same as file name */

void
main(void)
{
  uint16_t debug_data_xyz_u16 = 100u;

  UART_init();

  /* Replace UART_SendChar to user defined function which is send a byte thru uart*/
  LOG_Config(UART_SendChar);
  
  LOG_Restart();
  
  LOG_Trace(Application_Trace_message_EVENT);

  LOG_Info(Application_Info_massage_EVENT);
  
  LOG_Debug(Application_debug_message_EVENT, LOG_DATA_16, &debug_data_xyz_u16);
  
  /* condition true means warning will go */
  LOG_Warning(Application_Warning_message_EVENT, debug_data_xyz_u16 > 10u);
  
  while(1)
  {

  }
}
