CANBUS掩码/过滤器无法正常工作

你使用的是什么版本的和声（1？x或2？x）？



      以下为原文

    Which version of Harmony are you using (1.x or 2.x)?

我用和声V2Y02Y000



      以下为原文

    I am using Harmony v2_02_00b
 

两个观察（可能或可能不重要）：应该：PLBIK-Chan-ChhannUp更新（ChanaId1，1）；在开关/ case语句之外移动？而不是ReEngEnter（仅仅是一个编程的优点）的无符号int：Chan-MeaveEnEncInEngult= PLIPK-CuiMeaveEngIGET（ChanaId1）；



      以下为原文

     a couple of observations (may or may not matter):
 
Should the:   PLIB_CAN_ChannelUpdate(CAN_ID_1, 1);    be moved outside of the switch/case statement?
 
instead of unsigned int for r_event  (just a programming goodness):
CAN_MODULE_EVENT r_event = PLIB_CAN_ModuleEventGet(CAN_ID_1);

我一直在玩这个，但没有效果。当生成事件时，它才生成。这就是为什么在处理事件之前我不检查ID的原因。我相信这是真的，因为第4452页的图片在OrthyYelHelp.PDF版本2.02V上回到了问题的症结，如果我只使用0x0作为掩码和过滤器，我会得到最低优先级的消息。我要找的是Mease0x10FFAAD2，所以我将过滤器设置为这个值。我把面具设为0x1FFF000，因为我想确定我没有在某个地方漏掉一些地址。对于这些设置，我从CAN中断中看不到任何东西。我想我会开始关注PLIB，但是为PLIB生成的和谐代码看起来很好：我知道的事情是：1）它是连接的，因为我可以通过0x0过滤器看到总线上的最低优先级消息。2）如果我把面罩/过滤器换成总线上的其他地址，它就不起作用了。我觉得这是一个平凡的细节，但我不知道会是什么。这种模式和它有什么关系吗？我只是在听留言，非常感谢您的建议。

    I've been playing around with this, but to no avail.  When an event is generated, it's just generated.  This is why I do not check for the ID until I handle the event.   I believe this is true due to the image on page 4452 on version 2.02v of the harmony_help.pdf   Back to the crux of the issue, if I just use 0x0 for the mask and filter, I get the lowest priority message.  What I am looking for is message 0x10FFAAD2, so I set the filter to this value.   I set the mask to 0x1FFFF000 because I wanted to be sure that I wasn't missing some address somewhere.    For these settings, I see nothing from the CAN interrupt.  I figured that I'd start to look at PLIB, but the Harmony code generated for PLIB looks pretty good:
 
void DRV_CAN0_Initialize(void)
{

    /* Switch the CAN module ON */
    PLIB_CAN_Enable(CAN_ID_1);
    
    /* Switch the CAN module to Configuration mode. Wait until the switch is complete */
    PLIB_CAN_OperationModeSelect(CAN_ID_1, CAN_CONFIGURATION_MODE);
    while(PLIB_CAN_OperationModeGet(CAN_ID_1) != CAN_CONFIGURATION_MODE);

    PLIB_CAN_PhaseSegment2LengthFreelyProgrammableEnable(CAN_ID_1);

    //Set the Baud rate to 250 kbps
    PLIB_CAN_PropagationTimeSegmentSet(CAN_ID_1, 1-1);
    PLIB_CAN_PhaseSegment1LengthSet(CAN_ID_1, 3-1);
    PLIB_CAN_PhaseSegment2LengthSet(CAN_ID_1, 3-1);
    PLIB_CAN_SyncJumpWidthSet(CAN_ID_1, 1-1);
    PLIB_CAN_BaudRatePrescaleSet(CAN_ID_1, 49); // set to 1 higher then ECAN tool


    /* Assign the buffer area to the CAN module.
      In this case assign enough memory for 2
      channels, each with 8 message buffers.*/
    PLIB_CAN_MemoryBufferAssign(CAN_ID_1, can_message_buffer0);

    /* Configure CAN_ID_1 Channel for CAN_TX_RTR_DISABLED operation. Allocate 1 message buffer, and assign low medium priority for transmissions. */
    PLIB_CAN_ChannelForTransmitSet(CAN_ID_1, CAN_CHANNEL0, 1, CAN_TX_RTR_DISABLED, CAN_LOW_MEDIUM_PRIORITY);
    /* Configure CAN_ID_1 Channel for CAN_RX_FULL_RECEIVE operation. Allocate 1 message buffer, and assign low medium priority for transmissions. */
    PLIB_CAN_ChannelForReceiveSet(CAN_ID_1, CAN_CHANNEL1, 1, CAN_RX_FULL_RECEIVE);
    PLIB_CAN_FilterToChannelLink(CAN_ID_1, CAN_FILTER0, CAN_FILTER_MASK0, CAN_CHANNEL1);
    PLIB_CAN_ChannelEventEnable(CAN_ID_1, CAN_CHANNEL1, CAN_RX_CHANNEL_NOT_EMPTY);
    PLIB_CAN_FilterConfigure(CAN_ID_1, CAN_FILTER0, 0x10FFAAD2, CAN_EID);
    PLIB_CAN_FilterEnable(CAN_ID_1, CAN_FILTER0);

    PLIB_CAN_FilterMaskConfigure(CAN_ID_1, CAN_FILTER_MASK0, 0x1FFFF000, CAN_EID, CAN_FILTER_MASK_ANY_TYPE);

    /* Switch the CAN module to Normal mode. Wait until the switch is complete */
    PLIB_CAN_OperationModeSelect(CAN_ID_1, CAN_LISTEN_ALL_MESSAGES_MODE);
    while(PLIB_CAN_OperationModeGet(CAN_ID_1) != CAN_LISTEN_ALL_MESSAGES_MODE);

    PLIB_CAN_ModuleEventEnable(CAN_ID_1 , 0|CAN_All_EVENTS);

    /* Setup CAN_ID_1 Interrupt */
    PLIB_INT_SourceEnable(INT_ID_0,INT_SOURCE_CAN_1);
    PLIB_INT_VectorPrioritySet(INT_ID_0,INT_VECTOR_CAN1, INT_PRIORITY_LEVEL3);
    PLIB_INT_VectorSubPrioritySet(INT_ID_0,INT_VECTOR_CAN1, INT_SUBPRIORITY_LEVEL1);
}
 
The things that I know:  1) it's connected, as I can see the lowest priority message on the bus via the 0x0 filter.  2) I'm if I change the mask/filter to the other addresses on the bus, it doesn't work. 
I feel that this is a mundane detail in the configuration, but I have no idea what that would be.  Would the mode have something to do with it?  I'm just listening to messages.
 
Any suggestions would be greatly appreciated.  
 
 
 
 

在愚蠢的世界里，我删除了所有自动生成的和声文件，并从描述中重建一切。它神奇地开始工作。耸耸肩：我把这个粉刷成一个未知的和声错误。我会更仔细地看看是否能复制它。



      以下为原文

    In the world of silliness, I deleted all of the auto generated Harmony files and rebuilt everything from the description.  It magically started working.    I'm chalking this one up to an unknown Harmony error.  I'll be more careful to see if I can reproduce it.

嘿，伙计们！我也有同样的问题。我重建了代码，但仍然不起作用。你应该帮助我吗？

    Hey guys!
 
I'm having the same problem too. I rebuilt the code but still don't working. You should help me?
