Hello,
In an application with the nRF52832, Softdevice and SDK 17.1.0 I try to use the temperature sensor according to the peripheral example. I attach the temperature.c file code.
#include <stdint.h>
#include "nrf_temp.h"
// Function to initialize and read temperature from the TEMP peripheral using SDK functions
int32_t nrf_read_temperature(void) {
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. */
/* 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. */
return (temp);
}
However, I have problems executing the nrf_read_temperature() function because the program breaks without an specific reason. Should I use another code? Any suggestion?
Thank you very much in advance.
Regards,
Joel
