When an OUT request arrives, data is collected in the data store provided with the USBRegisterRequestHandler call. When the transfer is done, the callback is called. When an IN request arrives, the callback is called immediately to either put the control transfer data in the data store, or to get a pointer to control transfer data. The data is then packetised and sent to the host. <hr><h2>Define Documentation</h2><a class="anchor" name="5e88408279bd004961a1fbcf4a20cc0c"></a><!-- doxytag: member="usbcontrol.c::MAX_CONTROL_SIZE" ref="5e88408279bd004961a1fbcf4a20cc0c" args="" --><div class="memitem"><div class="memproto"> <table class="memname"> <tr> <td class="memname">#define MAX_CONTROL_SIZE 128 </td> </tr> </table></div><div class="memdoc"><p>maximum total size of control transfer data </div></div><p><a class="anchor" name="15136a2bda6efe224bf6d43d4849165a"></a><!-- doxytag: member="usbcontrol.c::MAX_REQ_HANDLERS" ref="15136a2bda6efe224bf6d43d4849165a" args="" --><div class="memitem"><div class="memproto"> <table class="memname"> <tr> <td class="memname">#define MAX_REQ_HANDLERS 4 </td> </tr> </table></div><div class="memdoc"><p>standard, class, vendor, reserved </div></div><p><hr><h2>Function Documentation</h2><a class="anchor" name="a315d521825a97d3693f82ec48aa5282"></a><!-- doxytag: member="usbcontrol.c::USBHandleControlTransfer" ref="a315d521825a97d3693f82ec48aa5282" args="(U8 bEP, U8 bEPStat)" --><div class="memitem"><div class="memproto"> <table class="memname"> <tr> <td class="memname">void USBHandleControlTransfer </td> <td>(</td> <td class="paramtype"><a class="el" href="type_8h.html#3cb25ca6f51f003950f9625ff05536fc">U8</a> </td> <td class="paramname"> <em>bEP</em>, </td> </tr> <tr> <td class="paramkey"></td> <td></td> <td class="paramtype"><a class="el" href="type_8h.html#3cb25ca6f51f003950f9625ff05536fc">U8</a> </td> <td class="paramname"> <em>bEPStat</em></td><td> </td> </tr> <tr> <td></td> <td>)</td> <td></td><td></td><td width="100%"></td> </tr> </table></div><div class="memdoc"><p>Handles IN/OUT transfers on EP0<p><dl compact><dt><b>Parameters:</b></dt><dd> <table border="0" cellspacing="2" cellpadding="0"> <tr><td valign="top"><tt>[in]</tt> </td><td valign="top"><em>bEP</em> </td><td>Endpoint address </td></tr> <tr><td valign="top"><tt>[in]</tt> </td><td valign="top"><em>bEPStat</em> </td><td>Endpoint status </td></tr> </table></dl></div></div><p><a class="anchor" name="baee648abed6949546fc94714e49d91c"></a><!-- doxytag: member="usbcontrol.c::USBRegisterRequestHandler" ref="baee648abed6949546fc94714e49d91c" args="(int iType, TFnHandleRequest *pfnHandler, U8 *pbDataStore)" --><div class="memitem"><div class="memproto"> <table class="memname"> <tr> <td class="memname">void USBRegisterRequestHandler </td> <td>(</td> <td class="paramtype">int </td> <td class="paramname"> <em>iType</em>, </td> </tr> <tr> <td class="paramkey"></td> <td></td> <td class="paramtype"><a class="el" href="usbapi_8h.html#cdc2d456f793c62f73c83a684b9eb67d">TFnHandleRequest</a> * </td> <td class="paramname"> <em>pfnHandler</em>, </td> </tr> <tr> <td class="paramkey"></td> <td></td> <td class="paramtype"><a class="el" href="type_8h.html#3cb25ca6f51f003950f9625ff05536fc">U8</a> * </td> <td class="paramname"> <em>pbDataStore</em></td><td> </td> </tr> <tr> <td></td> <td>)</td> <td></td><td></td><td width="100%"></td> </tr> </table></div><div class="memdoc"><p>Registers a callback for handling requests<p><dl compact><dt><b>Parameters:</b></dt><dd> <table border="0" cellspacing="2" cellpadding="0"> <tr><td valign="top"><tt>[in]</tt> </td><td valign="top"><em>iType</em> </td><td>Type of request, e.g. REQTYPE_TYPE_STANDARD </td></tr> <tr><td valign="top"><tt>[in]</tt> </td><td valign="top"><em>*pfnHandler</em> </td><td>Callback function pointer </td></tr> <tr><td valign="top"><tt>[in]</tt> </td><td valign="top"><em>*pbDataStore</em> </td><td>Data storage area for this type of request </td></tr> </table></dl></div></div><p><hr size="1"><address style="align: right;"><small>Generated on Fri Jul 27 12:07:02 2007 for LPCUSB by <a href="http://www.doxygen.org/index.html"><img src="doxygen.png" alt="doxygen" align="middle" border="0"></a> 1.5.1 </small></address></body></html>?? 快捷鍵說明
