Core Modules

These core modules are intended on being consistent across ports. Currently they are only implemented in the SAMD21 and ESP8266 ports. A module may not exist in a port if no underlying hardware support is present or if flash space is limited. For example, a microcontroller without analog features will not have analogio.
