microcontroller --- Pin references and cpu functionality

The microcontroller module defines the pins from the perspective of the microcontroller. See board for board-specific pin mappings.



CPU information and control, such as cpu.temperature and cpu.frequency (clock frequency). This object is the sole instance of microcontroller.Processor.


Dedicated delay method used for very short delays. Do not do long delays because this stops all other functions from completing. Think of this as an empty while loop that runs for the specified (delay) time. If you have other code or peripherals (e.g audio recording) that require specific timing or processing while you are waiting, explore a different avenue such as using time.sleep().


Disable all interrupts. Be very careful, this can stall everything.


Enable the interrupts that were enabled at the last disable.


Configure the run mode used the next time the microcontroller is reset but not powered down.

Parameters:run_mode (RunMode) -- The next run mode

Reset the microcontroller. After reset, the microcontroller will enter the run mode last set by on_next_reset.


This may result in file system corruption when connected to a host computer. Be very careful when calling this! Make sure the device "Safely removed" on Windows or "ejected" on Mac OSX and Linux.


Available non-volatile memory. This object is the sole instance of nvm.ByteArray when available or None otherwise.
