Hi,
I'm using nrf51822 / sd130 / sdk 12.1. I am doing minimizing current consumption. My main function is like below. I checked no wakeup in sleep mode. But, current consumption changes variously. It is wide from ~30uA to 1.5mA. What should I do additionally? I'm trying various condition.
thanks.
while (1)
{
// fucntion execute
NRF_CLOCK->TASKS_HFCLKSTART = 0; // for test
NRF_CLOCK->TASKS_HFCLKSTOP = 1; // for test
NRF_POWER->TASKS_LOWPWR = 1; // for test
// NRF_POWER->SYSTEMOFF = 1; // for test
// Make sure any pending events are cleared
__SEV();
__WFE();
// Enter System ON sleep mode
__WFE();
// watchdog
nrf_drv_wdt_channel_feed(m_channel_id); // wdt feed
NRF_CLOCK->TASKS_HFCLKSTOP = 0; // for test
NRF_CLOCK->TASKS_HFCLKSTART = 1; // for test
}
watchdog setting
// <1=> Run in SLEEP, Pause in HALT
// <8=> Pause in SLEEP, Run in HALT
// <9=> Run in SLEEP and HALT
// <0=> Pause in SLEEP and HALT
