unsigned char twi_get_data_from_transceiver	(	unsigned char *	msg,
		unsigned char	msgSize
	)

Call this function to read out the requested data from the TWI transceiver buffer.

first call twi_start_transceiver to send a request for data to the slave. Then Run this function to collect the data when they have arrived. Include a pointer to where to place the data and the number of bytes requested (including the address field) in the function call. The function will hold execution (loop) until the TWI_ISR has completed with the previous operation, before reading out the data and returning.

If there was an error in the previous transmission *the function will return the TWI error code.called when the TWI interrupt is triggered; that is whenever a TWI event has occurred. This function should not be called directly from the main application.

The function will hold execution (loop) until the TWI_ISR has completed with the previous operation.

Returns

If there was an error, then the function will return the TWI State code.

Call this function to resend the last message.

The driver will reuse the data previously put in the transceiver buffers. The function will hold execution (loop) until the TWI_ISR has completed with the previous operation, then initialize the next operation and return.

The first byte must contain the slave address and the read/write bit. Consecutive bytes contain the data to be sent, or empty locations for data to be read from the slave. Also include how many bytes that should be sent/read including the address byte. The function will hold execution (loop) until the TWI_ISR has completed with the previous operation, then initialize the next operation and return.
