Function Documentation

◆ bar_ils22qs_Init()

HAL_StatusTypeDef bar_ils22qs_Init ( I2C_HandleTypeDef * hi2c)

Initialise the ILPS22QS sensor and verify it is present on the I2C bus. The sensor is put into low-power standby mode after verification.

Parameters
hi2cPointer to the I2C handle.
Return values
HAL_OK– sensor found and initialised successfully.
HAL_ERROR– sensor not detected on the bus or initialisation failed.

◆ bar_ils22qs_Is()

int8_t bar_ils22qs_Is ( I2C_HandleTypeDef * hi2c,
int8_t tryInit )

Check if the ILPS22QS barometric pressure sensor is present on the I2C bus.

Parameters
hi2cPointer to the I2C handle.
tryInit1 – attempt to (re-)initialise if not yet done; 0 – no retry.
Return values
1– sensor is present and initialised.
0– sensor not detected.
