_INSERT_METHOD_SIGNATURE_HERE_

This method transfers all stored data frames from the TX buffer to a slave device and returns the received data frames as rxBuf array after the transfer has been completed. The returned rxBuf.length value contains the number of frames that are transferred to a slave device.

Returns	Description
rxBuf[]	array that contains the received data frames

Parameter	Description
nrOfFrames	number of the data frames that should be transfered

This method transfers nrOfFrames elements from the TX buffer to a slave device and returns the received data frames as rxBuf array after the transfer has been completed. The returned rxBuf.length value contains the number of frames that are transferred to a slave device.

Returns	Description
rxBuf[]	array that contains the received data frames

This method clears the TX buffer befor the new txBuf data frames are written to the TX buffer.

Parameter	Description
txBuf	array of frames that should be written to the TX buffer

The txBuf contains the array of data frames that should be transmitted to a slave device and returns the received data frames as rxBuf array after the transfer has been completed. The returned rxBuf.length value contains the number of frames that are transferred to a slave device.

Returns	Description
rxBuf[]	array that contains the received data frames

This method clears the TX buffer befor the new txBuf data frames are written to the TX buffer.

Parameter	Description
txBuf	array of frames that should be written to the TX buffer
offs	offset to the first data frame
nrOfFrames	number of the data frames that should be transfered

The txBuf contains the array of data frames and writes nrOfFrames elements according to the offset parameter offs into the TX buffer. This method returns the received data frames as rxBuf array after the transfer has been completed. The returned rxBuf.length value contains the number of frames that are transferred to a slave device.

Returns	Description
rxBuf[]	array that contains the received data frames

• A data transfer with the transferData method can only be used in master mode.
• The frames from the txBuf array are stored into the TX buffer.
• Some methods clear the TX buffer bevore new txBuf data are written into the TX buffer.
• Afterwards, the data transfer is initiated.
• The value of each frame ranging from 0 ... 255 with a data size select of 8-bit to 0 ... 65535 with a data size select of 16-bits (see open).
• Only the lower 16-bits of an intager value are transferred.
• The frames to be transfered are taken from the TX buffer according to the FIFO principle.
• The received data frames from a slave device are stored in the RX buffer and returned in the rxBuf array afterwards.
