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. <table border="0" cellpadding="0"><tr valign="top"><td><b>Author:</b><td> Jason Hill </td></tr><tr valign="top"><td> </td><td> David Gay </td></tr><tr valign="top"><td> </td><td> Philip Levis</td></tr></table><p><dl><dt>Components providing this interface:<dd> <a href="tos.system.UART.nc.html">tos.system.UART</a><br> <a href="tos.system.UARTM.nc.html">tos.system.UARTM</a><br></dl><p><dl><dt>Components requiring this interface:<dd> <a href="tos.system.FramerM.nc.html">tos.system.FramerM</a><br> <a href="tos.system.NoCRCPacket.nc.html">tos.system.NoCRCPacket</a><br></dl><p><table BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><tr BGCOLOR="#CCCCFF"><td><h3>Commands</h3></td></tr></table><ul><li> result_t <b>txByte</b>(uint8_t data)<menu> Transmits a byte over the radio <table border="0" cellpadding="0"></td></tr><tr valign="top"><td><br><b>Parameters:</b></td><td><menu><p STYLE="text-indent: -1cm"><b>data</b> - the byte to be transmitted </menu></td></tr><tr valign="top"><td><b>Returns:</b></td><td> SUCCESS if successful</td></tr></table></menu><p></ul><table BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><tr BGCOLOR="#CCCCFF"><td><h3>Events</h3></td></tr></table><ul><li> result_t <b>rxByteReady</b>(uint8_t data, bool error, uint16_t strength)<menu> Notification that the radio is ready to receive another byte <table border="0" cellpadding="0"></td></tr><tr valign="top"><td><br><b>Parameters:</b></td><td><menu><p STYLE="text-indent: -1cm"><b>data</b> - the byte read from the radio </p><p STYLE="text-indent: -1cm"><b>error</b> - determines the success of receiving the byte </p><p STYLE="text-indent: -1cm"><b>strength</b> - the signal strength of the received byte </menu></td></tr><tr valign="top"><td><b>Returns:</b></td><td> SUCCESS if successful</td></tr></table></menu><p><li> result_t <b>txByteReady</b>(bool success)<menu> Notification that the bus is ready to transmit/queue another byte <table border="0" cellpadding="0"></td></tr><tr valign="top"><td><br><b>Parameters:</b></td><td><menu><p STYLE="text-indent: -1cm"><b>success</b> - Notification of the successful transmission of the last byte </menu></td></tr><tr valign="top"><td><b>Returns:</b></td><td> SUCCESS if successful</td></tr></table></menu><p><li> result_t <a href="# result_t txDone(void)"><b>txDone</b> </a>(void)<menu> Notification that the transmission has been completed and the transmit queue has been emptied.</menu><p></ul><table BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><tr BGCOLOR="#CCCCFF"><td><h3>Events - Details</h3></td></tr></table> <a name=" result_t txDone(void)"></a> <h4>txDone</h4> result_t <b>txDone</b>(void)<P><menu> Notification that the transmission has been completed and the transmit queue has been emptied. <table border="0" cellpadding="0"><tr valign="top"><td><b>Returns:</b></td><td> SUCCESS always</td></tr></table></menu>⌨️ 快捷键说明
