Interface: ByteComm

A byte-level communication interface. It signals byte receptions and provides a split-phased byte send interface. txByteReady states that the component can accept another byte in its queue to send, while txDone states that the send queue has been emptied.

Components requiring this interface:

tos.lib.Util.UartDebuggerM
tos.system.FramerM
tos.system.NoCRCPacket

Commands

• result_t txByte(uint8_t data) Transmits a byte over the radio

  Parameters:	data - the byte to be transmitted
  Returns:	SUCCESS if successful

• result_t rxByteReady(uint8_t data, bool error, uint16_t strength) Notification that the radio is ready to receive another byte

  Parameters:	data - the byte read from the radio error - determines the success of receiving the byte strength - the signal strength of the received byte
  Returns:	SUCCESS if successful

• result_t txByteReady(bool success) Notification that the bus is ready to transmit/queue another byte

  Parameters:	success - Notification of the successful transmission of the last byte
  Returns:	SUCCESS if successful

• result_t txDone (void) Notification that the transmission has been completed and the transmit queue has been emptied.
