# Embedded diagnostic logger

Logging system for small microcontroller projects.

# Usage

```c
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)
  {

}
}

```

output in logger-client-console.py application

```
10:54:41    0.008 main    11  TRACE --> Application Trace message
10:54:41    0.010 main    13  INFO  --> Application Info massage
10:54:41    0.012 main    15  DEBUG --> Application debug message   [100]
10:54:41    0.015 main    17  WARN  --> Application Warning message
```
