ESP32打印日志

ESP32日志报文打印API测试，掌握Debug,Info,Warn以及Error四种日志报文输出，获取ESP32芯片相关信息并打印输出

1.日志打印API介绍

函数名	描述	案例
esp_chip_info(esp_chip_info_t* info)	info:芯片信息结构体指针	esp_chip_info(&info)
ESP_LOGI(const char* tag,char* format_msg)	打印信息: [tag:format_msg]	ESP_LOGI("Info","This is a Information"); ESP_LOGI("Info","ESP32 Chip Cores Count: %d",chip_info.cores); ESP_LOGI("Info","ESP32 Chip, WiFi%s%s,",(chip_info.features & CHIP_FEATURE_BT)?"/BT":"",(chip_info.features&CHIP_FEATURE_BLE) ? "/BLE":""); ESP_LOGI("Info","SPI Flash Chip Size: %dMByte %s flash",spi_flash_get_chip_size()/(1024*1024),(chip_info.features & CHIP_FEATURE_EMB_FLASH)?"Embedded" : "External");
esp_base_mac_addr_get(uint8_t MAC[6])	WiFi的MAC地址	esp_base_mac_addr_get(MAC) ESP_LOGI("Info", "Base MAC Addr : %02X.%02X.%02X.%02X.%02X.%02X",MAC[0],MAC[1],MAC[2],MAC[3],MAC[4],MAC[5]);
ESP_LOGW(const char* tag,char* msg)	打印报警:[tag,msg]	ESP_LOGW(“Warn”, “This is a Warn”)
ESP_LOGE(const char* tag,char* msg)	打印错误:[tag,msg]	ESP_LOGE(“Error”, “This is a Error”)
ESP_LOGD (const char* tag,char* msg)	打印调试:[tag,msg]	ESP_LOGD(“Debug”, “This is a Debug”)
ESP_LOGV(const char* tag,char* msg)	详细:[tag,msg]	ESP_LOGV(“Detial”, “This is a Detail”)
esp_restart()	软件复位	esp_restart();

2.功能设计

Info:CPU基本信息 如Flash Size,Core Num,RAM Size等
打印输出: Warn,Error信息

const static char *InfoTag = "Info";
const static char *WarnTag = "Warn";

	}else if(chip_info.model == 2){

	}else{

	}

	ESP_LOGI(InfoTag, ">>> ESP32芯片支持通讯方式: WIFI%s%s, ",
			(chip_info.features & CHIP_FEATURE_BT) ? "/BT" : "",
			(chip_info.features & CHIP_FEATURE_BLE) ? "/BLE" : "");

	ESP_LOGI(InfoTag, ">>> ESP32 Flash容量: %dMB %s flash", spi_flash_get_chip_size() / (1024 * 1024),
			(chip_info.features & CHIP_FEATURE_EMB_FLASH) ? "Embedded" : "External");

	ESP_LOGI(InfoTag, ">>> Free Heap Size is:  %d B",esp_get_free_heap_size());
	ESP_LOGI(InfoTag, ">>> Free Internal Heap Size is:  %d B",esp_get_free_internal_heap_size());
	ESP_LOGI(InfoTag, ">>> Free minimum Heap Size is:  %d B",esp_get_minimum_free_heap_size());

	esp_base_mac_addr_get(MAC);
	ESP_LOGI(InfoTag, ">>> 网络MAC地址:  %02X.%02X.%02X.%02X.%02X.%02X",MAC[0],MAC[1],MAC[2],MAC[3],MAC[4],MAC[5]);

	ESP_LOGI(InfoTag, ">>>===== ESP32芯片介绍结束 =====<<<");
	vTaskDelay(1000 / portTICK_PERIOD_MS);

	ESP_LOGW(WarnTag, ">>> This is a Warning!");

	ESP_LOGE(ErrorTag, ">>> This is a Error!");

	while(1){
		vTaskDelay(1000 / portTICK_PERIOD_MS);
	}
	// ESP_LOGI(TAG, "Restarting now.");
	// esp_restart();
}
