Chapter 2. API Reference
ESP_EARLY_LOGW(tag, format, ...)
macro to output logs in startup code at ESP_LOG_WARN level.
See ESP_EARLY_LOGE,ESP_LOGE, printf
ESP_EARLY_LOGI(tag, format, ...)
macro to output logs in startup code at ESP_LOG_INFO level.
See ESP_EARLY_LOGE,ESP_LOGE, printf
ESP_EARLY_LOGD(tag, format, ...)
macro to output logs in startup code at ESP_LOG_DEBUG level.
See ESP_EARLY_LOGE,ESP_LOGE, printf
ESP_EARLY_LOGV(tag, format, ...)
macro to output logs in startup code at ESP_LOG_VERBOSE level.
See ESP_EARLY_LOGE,ESP_LOGE, printf
_ESP_LOG_EARLY_ENABLED(log_level)
ESP_LOG_EARLY_IMPL(tag, format, log_level, log_tag_letter, ...)
ESP_LOGE(tag, format, ...)
ESP_LOGW(tag, format, ...)
ESP_LOGI(tag, format, ...)
ESP_LOGD(tag, format, ...)
ESP_LOGV(tag, format, ...)
ESP_LOG_LEVEL(level, tag, format, ...)
runtime macro to output logs at a specified level.
See printf
Parameters
• tag: tag of the log, which can be used to change the log level by esp_log_level_set at
runtime.
• level: level of the output log.
• format: format of the output log. see printf
• ...: variables to be replaced into the log. see printf
ESP_LOG_LEVEL_LOCAL(level, tag, format, ...)
runtime macro to output logs at a specified level. Also check the level with LOG_LOCAL_LEVEL.
See printf, ESP_LOG_LEVEL
ESP_DRAM_LOGE(tag, format, ...)
Macro to output logs when the cache is disabled. log at ESP_LOG_ERROR level.
Similar to
Usage: ESP_DRAM_LOGE(DRAM_STR("my_tag"), "format", orESP_DRAM_LOGE(TAG,
“format”, …)`, where TAG is a char* that points to a str in the DRAM.
Note Unlike normal logging macros, it’s possible to use this macro when interrupts are disabled or inside an
ISR.
See ESP_EARLY_LOGE, the log level cannot be changed per-tag, however esp_log_level_set(“*”, level)
will set the default level which controls these log lines also.
Note Placing log strings in DRAM reduces available DRAM, so only use when absolutely essential.
See esp_rom_printf,ESP_LOGE
ESP_DRAM_LOGW(tag, format, ...)
macro to output logs when the cache is disabled at ESP_LOG_WARN level.
See ESP_DRAM_LOGW,ESP_LOGW, esp_rom_printf
