Delay#
Basic delay functionality.
Simple delay routines for use with components that require small delays.
Functions#
Delay for a number of microseconds.
Initialize the delay driver's millisecond counter.
Delay for a number of milliseconds.
Check whether the current delay has expired.
Function Documentation#
delay_microseconds#
void delay_microseconds (uint32_t usecs)
Delay for a number of microseconds.
| N/A | usecs | Number of microseconds to delay |
Note
This function can be used without calling delay_init() first. This is not an accurate microsecond delay and can have a delay greater than expected, of about +50%. This error becomes significant for lower values delay.

void delay_init (void )
Initialize the delay driver's millisecond counter.

void delay_milliseconds (uint32_t msecs, bool blocking)
Delay for a number of milliseconds.
| N/A | msecs | Number of milliseconds to delay. The number should stay within a single TIMER0 overflow (approx. 3300 ms). |
| N/A | blocking | Whether to block until the delay has expired. If false, the delay_expired() function can be called to check whether the delay has expired. |

bool delay_expired (void )
Check whether the current delay has expired.
| N/A |
Returns
True if the delay has expired.
