Hi,
I would like to read the temperature of the nRF.
I tried to use the routine I found here in the forum
int32_t read_temperature(void)
{
// This function contains workaround for PAN_028 rev2.0A anomalies 28, 29,30 and 31.
int32_t temp;
nrf_temp_init();
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.
}
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);
return temp;
}
Sometimes works sometimes the system crash.
I notice the system crash when the SD in on.
Routine access directly to the registers: there are any other function or SD function (I am using S140) to read temperature?
Thanks
Alessandro
