Debugging MicroPython

When using the ESP32 port of MicroPython you can use the logging facilities provided by ESP-IDF. Typically you define a DEBUG_printf function of this type:

The ESP-IDF logging facility knows 5 levels of error logging:

ESP_LOGE: for errors
ESP_LOGW: for warnings
ESP_LOGI: for information messages (this level has been chosen in our example above)
ESP_LOGD: for debugging
ESP_LOGV: for verbose

You can set the logging level up to which you want to see the messages with

esp.osdebug(0,esp.LOG_INFO)

setting the level to "information". In this case LOGE, LOGW and LOGI messages will be shown but not LOGD and LOGV messages. If you set

esp.osdebug(None)

no messages will be shown.

The screen dump below shows the output of help(esp) with all the methods and constants defined in this module.
