pw_log_zephyr

Overview

This interrupt backend implements the pw_log facade. To enable, set CONFIG_PIGWEED_LOG=y. After that, logging can be controlled via the standard Kconfig options. All logs made through PW_LOG_* are logged to the Zephyr logging module pigweed.

Setting the log level

In order to remain compatible with existing Pigweed code, the logging backend respects PW_LOG_LEVEL. If set, the backend will translate the Pigweed log levels to their closest Zephyr counterparts:

Pigweed	Zephyr
PW_LOG_LEVEL_DEBUG	LOG_LEVEL_DBG
PW_LOG_LEVEL_INFO	LOG_LEVEL_INF
PW_LOG_LEVEL_WARN	LOG_LEVEL_WRN
PW_LOG_LEVEL_ERROR PW_LOG_LEVEL_CRITICAL PW_LOG_LEVEL_FATAL	LOG_LEVEL_ERR

Alternatively, it is also possible to set the Zephyr logging level directly via CONFIG_PIGWEED_LOG_LEVEL.
