Definition at line 54 of file io1_xplained.h.

Initialize the given IO1 Xplained extension.

Parameters

[out]	dev	Initialized device descriptor of IO1 Xplained extension
[in]	params	Device initialization parameters

Returns: IO1_XPLAINED_OK on success; -IO1_XPLAINED_NOTEMP if temperature sensor initialization failed; -IO1_XPLAINED_NOSDCARD if sdcard initialization failed; -IO1_XPLAINED_NOLED if LED initialization failed; -IO1_XPLAINED_NOGPIO1 if GPIO1 initialization failed; -IO1_XPLAINED_NOGPIO2 if GPIO2 initialization failed

int io1_xplained_read_light_level ( uint16_t * light )

Read light sensor level on the IO1 Xplained extension.

Parameters

[out] light Light level value (between 0 and 1023)

Returns: IO1_XPLAINED_READ_OK on success; -IO1_XPLAINED_READ_ERR when the value cannot be read
