外部中断问题

你好Patrik，
 
 
1）低级驱动程序中有一些例子（例如：ADC）
如何定义IRQ处理程序
你可以使用OSAL_IRQ_HANDLER
 
 
OSAL_IRQ_HANDLER（SPC5_ADC0_WD_HANDLER）{
 uint32_t isr;
 
 
 OSAL_IRQ_PROLOGUE（）;
 
 
 isr = ADCD1.adc_tagp-＆gt; WTISR.R;
 ADCD1.adc_tagp-＆gt; WTISR.R = isr;
 adc_lld_serve_interrupt（＆amp; ADCD1，isr）;
 
 
 OSAL_IRQ_EPILOGUE（）;
}
 
 
在你的情况下，
您可以在SIUL第48章中使用外部中断
和方便的EIRQ [X]第48.4章
 
 
你应该使用vector41，vector42，vector 43或vector 44
 
 
41 0x0290 16 SIU外部IRQ_0 SIUL
42 0x02A0 16 SIU外部IRQ_1 SIUL
43 0x02B0 16 SIU外部IRQ_2 SIUL
44 0x02C0 16 SIU外部IRQ_3 SIUL
 
 
2）对于映射，您应该使用IO设置并在良好模式下设置好的端口/功能
 第4章从方便的表''功能汇总''
 
 
3）
在您的IRQ处理程序中，您应该：
if（palReadPad（PORT_D，PD_BUTTON1）== 0）{
 palTogglePad（PORT_D，PD_LED5）;
 }
 
 
 最好的祝福

Hello Patrik ,


1)  there are some examples in low level driver (example : ADC)
how to define an IRQ Handler
you can use OSAL_IRQ_HANDLER


OSAL_IRQ_HANDLER(SPC5_ADC0_WD_HANDLER) {
  uint32_t isr;


  OSAL_IRQ_PROLOGUE();


  isr = ADCD1.adc_tagp->WTISR.R;
  ADCD1.adc_tagp->WTISR.R = isr;
  adc_lld_serve_interrupt(&ADCD1, isr);


  OSAL_IRQ_EPILOGUE();
}


in your case ,  
You can use External INTERRUPT In SIUL chapter 48
and the convenient EIRQ[X] chapter 48.4


you should use vector41 , vector42, vector 43 or vector 44


41 0x0290 16 SIU External IRQ_0 SIUL
42 0x02A0 16 SIU External IRQ_1 SIUL
43 0x02B0 16 SIU External IRQ_2 SIUL
44 0x02C0 16 SIU External IRQ_3 SIUL


2) for mapping you should use IO Settings and set your good port/function in the good mode
    chap 4 from the convenient table ''function summary''


3)  
in your IRQ handler you should have :
if (palReadPad(PORT_D, PD_BUTTON1) == 0) {
      palTogglePad(PORT_D, PD_LED5);
    }


   Best regards

你好，Erwan，
 
 
 感谢您的帮助，但对我来说还有一些悬而未决的问题。我现在理解的是如何定义IRQ Handler。我调整了您的代码示例，按下评估板上的按钮S2应激活LED7。
OSAL_IRQ_HANDLER（BUTTON1）{
 
 OSAL_IRQ_PROLOGUE（）;
 
 
（palReadPad（PORT_G，PG_BUTTON_S2）== 0）{
 palClearPad（PORT_G，PA_LED7）; // LED连接到+ 3,3V
 }
 
 OSAL_IRQ_EPILOGUE（）;
 }
出于测试目的，我将处理程序放在main.c的main函数中。
 
 但是，我仍然不确定中断向量的定义和配置。按钮S2连接到引脚G [8]，意味着EIRQ（21）。我知道vector41到vector44是外部中断的向量，这意味着所有32个可能的外部中断。因为按钮S2连接到G [8]，相应的中断向量是vector43（EIRQ [16:23]）。
 因此，我在main.c＃define BUTTON1 vector43中定义了向量43
我使用应用程序配置将引脚G [8]定义为输入，并定义了名称PG_BUTTON_S2。根据产品手册，当使用引脚作为输入时，不需要PADSEL初始化。带LED的引脚定义为推挽输出。
你知道我做错了吗？它没有工作并调试代码显示，从未到达IRQ处理程序。
最好的祝福，
帕特里克

Hello Erwan,


Thanks for your help, but there are still some open questions for me. What I understand now is how I have to define the IRQ Handler. I adapted your code example that pressing the button S2 on the eval board should activate LED7.  
OSAL_IRQ_HANDLER(BUTTON1){

     OSAL_IRQ_PROLOGUE();

         
(palReadPad(PORT_G,PG_BUTTON_S2)==0){  
             palClearPad(PORT_G,PA_LED7); //LED is connected to +3,3V
         }  

         OSAL_IRQ_EPILOGUE();
}  
For testing purpose, I put the handler in the main function in main.c .

But still, I am not sure about definition and configuration of the interrupt vector. The button S2 is connected to the Pin G[8], means EIRQ(21). I understand that vector41 to vector44 are the vectors for external interrupts which means all together 32 possible external interrupts. Because button S2 is connected to G[8] the corresponding interrupt vector is vector43 (EIRQ[16:23]).
Therefore, i defined vector 43 in main.c#define BUTTON1 vector43
I used the Application Configuration to define the pin G[8] as an input and defined the name PG_BUTTON_S2. According to the product manual, a PADSEL initilization is not required when using the pin as an input. The pin with the LED is defined as a push-pull output.
Do you know what I did wrong? It is not working and debugging the code shows, that the IRQ Handler is never reached.
Best regards,
Patrik

自从我上次在这个论坛上写作以来，我多次尝试解决我的中断问题。与此同时，我甚至可以使用PIT模块生成周期性中断并让发现板的LED切换。我不得不说，由于硬件问题，我改为更小的板 - SPC560D发现板。
 
 使用PIT模块工作得很好，但我仍然无法使用外部中断。对程序进行补偿显示，按下按钮时设置了中断标志。但由于原因不明，中断处理程序永远不会执行。我真的不明白这一点，因为我做了一切，就像我使用定时器中断一样。有谁知道这可能是什么原因或我可能忘记配置的？
 
 谢谢，
 帕特里克

Since the last time I write in this forum, I was trying many times to solve my interrupt issue. In the mean time, I was even able to use the PIT module to generate a periodic interrupt and let the LED of the discovery board toggle. I have to say that I changed to a smaller board - the SPC560D discovery board because of a hardware problem.

Using the PIT module works really fine, but still I am not able to use the external interrupt. Debbuging the program shows me, that the interrupt flag is set when pressing the button. But because of an unknown reason, the interrupt handler is never executed. I really don´t understand this because i did everything as I did to use the timer interrupt. Has anybody an idea what could be the reason for that or what I maybe forget to configure?

Thanks,
Patrik

你好，
 
 
 最后，我解决了我的问题。我只是忘了为相应的焊盘设置中断使能位。
 
 最好的祝福，

Hello,


Finally, I solved my problem. I just forgot to set the interrupt enable bit for the corresponding pad.

Best regards,
Patrik

你好Patrik，
 
 
这是一个好消息;-)
无论如何，我们将在应用程序库的新版本中添加一个“测试应用程序”'相对''如何正确使用EIRQ''。
 
 最好的祝福

Hello Patrik ,


it is a good news ;-)
Anyway , we will add in the new release of Application repository a ''test application'' relative ''how to use correctly the EIRQ''.

           Best regards
