uint32_t ClearCore::SysTiming::Microseconds

(

)

Number of microseconds elapsed since the ClearCore was initialized.

Uses the processor's cycle counter register to calculate the number of microseconds elapsed.

// Implement a timeout of 750 microseconds.
uint32_t timeout = 750;
uint32_t start = Microseconds();
while (Microseconds() - start < timeout) {
    // wait for timeout...
}

Returns

Number of microseconds since board initialization.

Note

Rolls over every ~71.5 minutes (at UINT32_MAX microseconds)

volatile const uint32_t& ClearCore::SysTiming::Milliseconds ( )

inline

Number of milliseconds elapsed since the ClearCore was initialized.

Uses the fast update interrupt counter to retrieve the number of milliseconds elapsed.

// Implement a timeout of 2000 milliseconds.
uint32_t timeout = 2000;
uint32_t start = Milliseconds();
while (Milliseconds() - start < timeout) {
    // wait for timeout...
}

Returns

Number of milliseconds since board initialization.

Note

Rolls over every ~49.7 days (at UINT32_MAX milliseconds)

void ClearCore::SysTiming::ResetMicroseconds

(

)

Resets the microsecond timer.

// Implement a timeout of 750 microseconds.
uint32_t timeout = 750;
ResetMicroseconds();
while (Microseconds() < timeout) {
    // wait for timeout...
}

void ClearCore::SysTiming::ResetMilliseconds

(

)

Resets the millisecond timer.

// Implement a timeout of 2000 milliseconds.
uint32_t timeout = 2000;
ResetMilliseconds();
while (Milliseconds() < timeout) {
    // wait for timeout...
}
