uBit Base API¶
init¶
int init()
Description
Post constructor initialisation method.
sleep¶
void sleep( uint32_t milliseconds)
Description
Delay execution for the given amount of time.
If the scheduler is running, this will deschedule the current fiber and perform a power efficient, concurrent sleep operation.
If the scheduler is disabled or we're running in an interrupt context, this will revert to a busy wait.
Alternatively: wait, wait_ms, wait_us can be used which will perform a blocking sleep operation.
Parameters
uint32_tmilliseconds - the amount of time, in ms, to wait for. This number cannot be negative.
Returns
MICROBIT_OK on success, MICROBIT_INVALID_PARAMETER milliseconds is less than zero.
systemTime¶
unsigned long systemTime()
Description
Determine the time since this MicroBit was last reset.
Returns
The time since the last reset, in milliseconds.
Note
This will value overflow after 1.6 months.
Component Constructor¶
Advanced users only
Do not use this unless you really know what you're doing. It's usually best to use uBit.
MicroBit()
Description
Constructor.
Create a representation of a Genuino Zero device, which includes member variables that represent various device drivers used to control aspects of the board.
