sl_sensor_hall_get(float *field_strength, bool *alert, bool *tamper)
Function Documentation#
sl_sensor_hall_init#
sl_status_t sl_sensor_hall_init (void )
Parameters
| Type | Direction | Argument Name | Description |
|---|---|---|---|
| void | N/A |
Initialize hall sensor.
Note
With certain boards (e.g. 4184A, 4184B), using this initialization function enables other sensors, because they're on the same enable pin. Please take that into account when using this function.
Returns
Status of the operation.
sl_sensor_hall_deinit#
void sl_sensor_hall_deinit (void )
Parameters
| Type | Direction | Argument Name | Description |
|---|---|---|---|
| void | N/A |
Deinitialize hall sensor.
Warnings
With certain boards (e.g. 4184A, 4184B), using this deinitialization function disables other sensors, because they're on the same enable pin. Please use with caution.
sl_sensor_hall_get#
sl_status_t sl_sensor_hall_get (float * field_strength, bool * alert, bool * tamper)
Parameters
| Type | Direction | Argument Name | Description |
|---|---|---|---|
| float * | [out] | field_strength | Field strength level (in mT). |
| bool * | [out] | alert | Field strength has reached the alert level. |
| bool * | [out] | tamper | Field strength has reached the tamper level. |
Getter for hall sensor measurement data. Returns
Status of the operation.
