Function xensiv_pasco2_init_uart(xensiv_pasco2_t *, void *)

Function Documentation

int32_t xensiv_pasco2_init_uart(xensiv_pasco2_t *dev, void *ctx)

Initializes the XENSIV™ PAS CO2 device using the UART interface. It initializes the dev structure, verifies the integrity of the communication layer of the serial communication interface, and checks whether the sensor is ready.

Parameters

  • dev – [inout] Pointer to a XENSIV™ PAS CO2 sensor device structure allocated by user, but the init function will initialize its contents

  • ctx – [in] Pointer to the platform-specific I2C communication handler

Returns

XENSIV_PASCO2_OK if the initialization was successful; an error indicating what went wrong otherwise
