Method Detail

timeUs

public static long timeUs()

Reads the system time.

Returns:

System time in µs

timeNs

public static long timeNs()

Reads the system time.

Returns:

System time in ns

blink

public static void blink(int nTimes)

Blinks LED on GPIO_WKUP_7, nTimes with approx. 100µs high time and 100µs low time, blocks for 1s

Parameters:

nTimes - Number of times the led blinks.

enableInterrupts

public static void enableInterrupts()

Enables interrupts globally. Individual interrupts for peripheral components must be enabled locally.

checkStack

public static void checkStack()

Blinks LED on GPIO_WKUP_7 if stack end was overwritten
