- group nrfx_temp
Temperature sensor (TEMP) driver.
TEMP default configuration.
nrfx_err_t nrfx_temp_init(nrfx_temp_config_t const *p_config, nrfx_temp_data_handler_t handler)
Function for initializing the TEMP driver.
p_config – [in] Pointer to the structure with initial configuration.
handler – [in] Data handler provided by the user. If not provided, the driver is initialized in blocking mode.
- Return values
NRFX_SUCCESS – Driver was successfully initialized.
NRFX_ERROR_ALREADY_INITIALIZED – Driver was already initialized.
Function for uninitializing the TEMP driver.
NRFX_STATIC_INLINE int32_t nrfx_temp_result_get(void)
Function for getting the temperature measurement in a 2’s complement signed value representation.
This function returns the last value prepared by the TEMP peripheral. In blocking mode, it should be used after calling the nrfx_temp_measure() function. In non-blocking mode, it is called internally by the driver, and the value it returns is passed to the data handler.
Temperature measurement result in a 2’s complement signed value representation.
int32_t nrfx_temp_calculate(int32_t raw_measurement)
Function for calculating the temperature value in Celsius scale from raw data.
The returned temperature value is in Celsius scale, multiplied by 100 For example, the actual temperature of 25.75[C] will be returned as a 2575 signed integer. Measurement accuracy is 0.25[C].
raw_measurement – [in] Temperature value in a 2’s complement signed value representation.
Temperature measurement result.
Function for starting the temperature measurement.
Non-blocking mode: This function returns immediately. After a measurement, the handler specified during initialization is called, with measurement result as the parameter.
Blocking mode: This function waits until the measurement is finished. The value should be read using the nrfx_temp_result_get() function.
- Return values
In non-blocking mode: Measurement was started. An interrupt will be generated soon.
In blocking mode: Measurement was started and finished. Data can be read using thenrfx_temp_result_get() function.
In non-blocking mode: Not applicable.
In blocking mode: Measurement data ready event did not occur.
