Those messages are defined in kalimba_messsages.h, which is supplied as a kalimba include file but not as a VM include file (since no such messages will reach the VM code.)<p><a class="el" href="kalimba__standard__messages_8h.html">kalimba_standard_messages.h</a> lists the standard messages which pass between kalimba and the VM application. Those are typically sent by the CSR supplied DSP libraries or sample VM applications. All messages used here are in the range 0x7000 - 0x7FFF. Any customer specific messages must use numbers less than this.<p>In the descriptions of each message, the four arguments are referred to by number (0..3) after their name, for example period (1) means that the period parameter is the second of the four parameters,<hr><h2>Define Documentation</h2><a class="anchor" name="a0" doxytag="kalimba_standard_messages.h::KALIMBA_MSG_GO" ></a><p><table class="mdTable" width="100%" cellpadding="2" cellspacing="0"> <tr> <td class="mdRow"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top"> #define KALIMBA_MSG_GO 0x7000 </td> </tr> </table> </td> </tr></table><table cellspacing=5 cellpadding=0 border=0> <tr> <td> </td> <td><p>Indicates that the VM application has done all of its streamconnects and hence the dsp can start reading/writing data to its ports. <p>MESSAGE: Go (VM APPLICATION --> KALIMBA) </td> </tr></table><a class="anchor" name="a1" doxytag="kalimba_standard_messages.h::KALIMBA_MSG_SBCDEC_CONVERT_TO_MONO" ></a><p><table class="mdTable" width="100%" cellpadding="2" cellspacing="0"> <tr> <td class="mdRow"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top"> #define KALIMBA_MSG_SBCDEC_CONVERT_TO_MONO 0x7010 </td> </tr> </table> </td> </tr></table><table cellspacing=5 cellpadding=0 border=0> <tr> <td> </td> <td><p>Tells the sbc decoder to convert stereo streams to mono. <p>MESSAGE: SBC decoder convert to mono (VM APPLICATION --> KALIMBA)<p><dl compact><dt><b>Parameters:</b></dt><dd> <table border="0" cellspacing="2" cellpadding="0"> <tr><td></td><td valign=top><em>mono</em> </td><td>(0), 1 means convert to mono, 0 means leave as stereo </td></tr> </table></dl> </td> </tr></table><a class="anchor" name="a2" doxytag="kalimba_standard_messages.h::KALIMBA_MSG_SBCENC_SET_BITPOOL" ></a><p><table class="mdTable" width="100%" cellpadding="2" cellspacing="0"> <tr> <td class="mdRow"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top"> #define KALIMBA_MSG_SBCENC_SET_BITPOOL 0x7020 </td> </tr> </table> </td> </tr></table><table cellspacing=5 cellpadding=0 border=0> <tr> <td> </td> <td><p>Tells the sbc encoder what bitpool value to encode using and hence the dsp can start reading/writing data to its ports. <p>MESSAGE: SBC encoder set bitpool (VM APPLICATION --> KALIMBA)<p><dl compact><dt><b>Parameters:</b></dt><dd> <table border="0" cellspacing="2" cellpadding="0"> <tr><td></td><td valign=top><em>bitpool</em> </td><td>(0), the bitpool to use (valid range is 2..250.) </td></tr> </table></dl> </td> </tr></table><a class="anchor" name="a3" doxytag="kalimba_standard_messages.h::KALIMBA_MSG_SBCENC_SET_PARAMS" ></a><p><table class="mdTable" width="100%" cellpadding="2" cellspacing="0"> <tr> <td class="mdRow"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top"> #define KALIMBA_MSG_SBCENC_SET_PARAMS 0x7021 </td> </tr> </table> </td> </tr></table><table cellspacing=5 cellpadding=0 border=0> <tr> <td> </td> <td><p>Tells the sbc encoder what encoder parameters to use. <p>MESSAGE: SBC encoder set parameters (VM APPLICATION --> KALIMBA)<p><dl compact><dt><b>Parameters:</b></dt><dd> <table border="0" cellspacing="2" cellpadding="0"> <tr><td></td><td valign=top><em>param</em> </td><td>(0) the format is as follows (see SBC spec) bit 6-7: sampling frequency, bit 4-5: blocks, bit 2-3: channel_mode, bit 1: allocation method, bit 0: subbands </td></tr> </table></dl> </td> </tr></table><a class="anchor" name="a4" doxytag="kalimba_standard_messages.h::KALIMBA_MSG_MP3DEC_CONVERT_TO_MONO" ></a><p><table class="mdTable" width="100%" cellpadding="2" cellspacing="0"> <tr> <td class="mdRow"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top"> #define KALIMBA_MSG_MP3DEC_CONVERT_TO_MONO 0x7030 </td> </tr> </table> </td> </tr></table><table cellspacing=5 cellpadding=0 border=0> <tr> <td> </td> <td><p>Tells the mp3 decoder to convert stereo streams to mono. <p>MESSAGE: MP3 decoder convert to mono (VM APPLICATION --> KALIMBA)<p><dl compact><dt><b>Parameters:</b></dt><dd> <table border="0" cellspacing="2" cellpadding="0"> <tr><td></td><td valign=top><em>mono</em> </td><td>(0), 1 means convert to mono, 0 means leave as stereo </td></tr> </table></dl> </td> </tr></table><a class="anchor" name="a5" doxytag="kalimba_standard_messages.h::KALIMBA_MSG_AACDEC_CONVERT_TO_MONO" ></a><p><table class="mdTable" width="100%" cellpadding="2" cellspacing="0"> <tr> <td class="mdRow"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top"> #define KALIMBA_MSG_AACDEC_CONVERT_TO_MONO 0x7040 </td> </tr> </table> </td> </tr></table><table cellspacing=5 cellpadding=0 border=0> <tr>⌨️ 快捷键说明
