So I looked at the example of the temprature read and I got the following code:
NRF_TEMP->TASKS_START = 1; /** Start the temperature measurement. */
/* Busy wait while temperature measurement is not finished, you can skip waiting if you enable interrupt for DATARDY event and read the result in the interrupt. */
/*lint -e{845} // A zero has been given as right argument to operator '|'" */
while (NRF_TEMP->EVENTS_DATARDY == 0)
{
// Do nothing. //THIS HERE IS THE TROUBLE!!!!
}
NRF_TEMP->EVENTS_DATARDY = 0;
/**@note Workaround for PAN_028 rev2.0A anomaly 29 - TEMP: Stop task clears the TEMP register. */
temp = (nrf_temp_read() / 4);
/**@note Workaround for PAN_028 rev2.0A anomaly 30 - TEMP: Temp module analog front end does not power down when DATARDY event occurs. */
NRF_TEMP->TASKS_STOP = 1; /** Stop the temperature measurement. */
NRF_LOG_INFO("Actual temperature: %d", (int)temp);
But the problem I got is with the: while (NRF_TEMP->EVENTS_DATARDY == 0), I don't want to keep checking a while loop for and risk getting stuck here for like all time!
Also how many measurements does NRF_TEMP->TASKS_START = 1; /** Start the temperature measurement. */ take. I ask this cause I want also to be power efficient.
What would be the best approach to stay power efficient and avoid the risk of getting stuck in a while loop.
