esp32_common

holds common components for esp32 applications The current CMakeList.txt places this folder at the same level with application folder
    --/application folder
        --/main
        --/...
    --/esp32_common
        --/cmds
        --/tcp
        --/utils
If you place it differently update CMakeList.txt

The picture below shows how framework is initialized with respect the common components.

esp32_common/cmds

implements system and wifi utility commands

Note about console command

console on | off | tcp

on --> display messages (printfs, ESP_LOGx) on the serial console
tcp --> redirects all messages to LOG_SERVER listening on LOG_PORT (tcp_log.h)

on the server machine just run ncat -l LOG_PORT -k

off --> mute all your messages, but IDF components using printf directly cannot be muted

esp32_common/AD7811

implements primitives to start conversion and read data for AD7811

esp32_common/tcp
