How is embedded-log used?

1: Add three files to your project directory

• log_cfg.h
• log.h
• log.c

2: Init log funtcion

• Output to the serial port

char g_log_buff[512];

void MID_LOG_Put(const char *str)
{
	HAL_UART_Send((UINT_8 *)str, strlen(str));
}

void MID_LOG_Init(void)
{
	HAL_UART_Init();
	log_init(g_log_buff, sizeof(g_log_buff), MID_LOG_Put);
}

• Output to the usb/screen/flash

void MID_LOG_Put(const char *str)
{
	HID_USB_WriteData((UINT_8 *)str, strlen(str));
}

void MID_LOG_Put(const char *str)
{
	MID_TFT_DisInfo_n((UINT_8 *)str, strlen(str), 0, 0);
}

void MID_LOG_Put(const char *str)
{
	MID_FlashWrite(0x8000, (UINT_8 *)str, strlen(str));
}

3: Used function

  LOG_WRN("The file system is not initialized.");
  LOG_INF("init file system ok.");
  LOG_ERR("recv data error!");
  LOG_ASS(g_test_count > 101);

  LOG_INF("get data from queue.");
  u16DataLen = (u16DataLen > 1024) ? 1024 : u16DataLen;
  LOG_DBG("Msg recv length: %d", u16DataLen);
  LOG_DBG_HEX("BT Msg:", g_BtMsgBufCom, u16DataLen);

Advanced used

• log_cfg.h file configuration instructions

#define LOG_ENABLE			//关闭日志功能
#define LOG_CONFIG_LEVEL 4		//设置日志等级
#define LOG_CONFIG_COLOR		//是否开启彩色输出, 默认开启
#define LOG_CONFIG_TAGS			//是否输出日志类型标签, 默认输出
#define LOG_CONFIG_NEWLINE		//是否使用换行符"\n"
