UTIL_sleepInit
uint32_t UTIL_sleepInit(void)
Sets up the RTC timer used for sleep functions.
Definition: util_sleep.c:53
UTIL_supplyGetType
uint8_t UTIL_supplyGetType(void)
Returns the type of the power supply.
Definition: util_supply.c:291
UTIL_isLowPower
bool UTIL_isLowPower(void)
Checks if the current power supply has low power capability.
Definition: util_supply.c:305
UTIL_delay
void UTIL_delay(uint32_t ms)
Delays number of msTick Systicks (1 ms)
Definition: util.c:97
UTIL_waitForEvent
uint32_t UTIL_waitForEvent(uint32_t timeout)
Delays number of milliseconds in sleep mode (EM2) using the RTC but but returns if an event wakes up ...
