Component: Microcontroller
===================
This is the component provided by the [[block:microcontroller|Microcontroller Case]].

These callbacks can only be called by the microcontroller itself, or its direct neighbors (i.e. other computers that share a face with the microcontroller). Note that since microcontrollers cannot access external components they cannot interact with each others microcontroller components, but a computer can access a neighbouring microcontroller.

Component name: `microcontroller`.  
Callbacks:

- `setSideOpen(side: number, open: boolean): boolean`  
  Set whether network messages are sent via the specified side.
- `start(): boolean`  
  Starts the microcontroller. Returns true if the state changed.
- `isRunning(): boolean`  
  Returns whether the microcontroller is running.
- `isSideOpen(side: number): boolean`
  Get whether network messages are sent via the specified side.
- `lastError(): string`
  Returns the reason the microcontroller crashed, if applicable. Returns nil if no crash has occurred.
- `stop(): boolean`
  Stops the microcontroller. Returns true if the state changed.
