Function Documentation

pingI2C()

void pingI2C	(	optVAL_t	ret[],
		optVAL_t	ret_len
	)

Sends a byte to a certain I²C-Device.

Note

Using I²C won't block the analog pins!

Parameters

ret	an array of optVAL_t
ret_len	the length of the array

readI2C()

void readI2C ( optVAL_t  deviceID, optVAL_t  ret[], optVAL_t  ret_len, bool  blocking = true  )

inline

Reads a special amount of bits from a certain I²C-Device.

Note

Using I²C won't block the analog pins!

Parameters

deviceID	the target device
ret	the buffer to send
ret_len	size of buffer
blocking	should the Arduino wait until there is Data?

sendI2C() [1/2]

optVAL_t sendI2C	(	optVAL_t	deviceID,
		byte *	buf,
		byte	buf_len
	)

Sends a buffer of bytes to a certain I²C-Device.

Note

Using I²C won't block the analog pins!

Parameters

deviceID	the target device
buf	the buffer to send
buf_len	size of buffer

Returns

0 Transmission went well :D

1 ERROR: data too long for transmit buffer

2 ERROR: NACK transmitting address

3 ERROR: NACK transmitting data

4 ERROR: UNKNOWN

sendI2C() [2/2]

optVAL_t sendI2C	(	optVAL_t	deviceID,
		byte	buf
	)

Sends a byte to a certain I2C-Device.

Note

Using I2C won't block the analog pins!

Parameters

deviceID	the target device
buf	the buffer to send

Returns

0 Transmission went well :D

1 ERROR: data too long for transmit buffer

2 ERROR: NACK transmitting address

3 ERROR: NACK transmitting data

4 ERROR: UNKNOWN
