如何配置一个GPIO口为接受输入中断模式？

PAD_CONF 寄存器中先将引脚设GPIO
然后再GPIO_IRQENABLE设置引脚的中断使能

这个是所有的么，那上升沿触发还是下降沿这些都不明确啊 ， 只用设置这两个么？

或者你帮我看看这篇文章问题出在哪里？
All,
I currently have an issue setting up an interrupt on the OMAP 3530 IVA module(a.k.a DSP) . I am trying to use GPIO 22 and 23 for the interrupt. I first configure the appropriate padconfig register to Mux_Mode_4 and input enable
// gpio 22
pSTBCtx->Hardware_Context.pPadConfig->CONTROL_PADCONF_ETK_D8=(MUX_MODE_4|INPUT_ENABLE);
// gpio 23
pSTBCtx->Hardware_Context.pPadConfig->CONTROL_PADCONF_ETK_D9=(MUX_MODE_4|INPUT_ENABLE);
I then setup the bank 1 registers as shown below
#define GPIO_22_BIT_OFFSET  (1<<22)
#define GPIO_23_BIT_OFFSET  (1<<23)
#define SCHEDULE_REQUEST GPIO_22_BIT_OFFSET
#define COLLECTION_DONE GPIO_23_BIT_OFFSET
pSTBCtx->Hardware_Context.pBank1->OE|=SCHEDULE_REQUEST|COLLECTION_DONE;
pSTBCtx->Hardware_Context.pBank1->RISINGDETECT|=SCHEDULE_REQUEST|COLLECTION_DONE ;
pSTBCtx->Hardware_Context.pBank1->SETIRQENABLE2=SCHEDULE_REQUEST ;
pSTBCtx->Hardware_Context.pBank1->SETIRQENABLE2=COLLECTION_DONE ;
At this point I see the following in the Bank registers.

As you can see the IRQSTATUS2 indicates that the GPIO 22 has triggered.
I now enable the Wugen with following call
#define EVENT_ID_BANK_1 73
HWI_enableWugen(EVENT_ID_BANK_1);
I read the  WUGEN_MEVTSET1 register below:
0xEFFFFFFF
This indicates that IRQ 28  is unmasked(I think). However when I read the WUGEN_PENDEVT0 register. I get:
0x00008000
I think the value should be 0x1xxxxxxx.
I then map the event to an interrupt:
#define HWINT_BANK6 7
HWI_eventMap(HWINT_BANK6,EVENT_ID_BANK_1);
I then Plug the ISR
//The ISR needs to be plugged
HWI_dispatchPlug(HWINT_BANK6,Gpio_Bank6_ISR,-1,NULL);
Finally I enable the IER
//The corresponding IER bit needs to be enabled.
C64_enableIER(1< But I never see the ISR get called and the corresponding bit in the IFR never gets set.
Any ideas?
Thanks,

设置电平触发为GPIODETECT1 和GPIODETECT2
上升沿触发为RISINGDETECT
下降沿触发为FALLENDETECT
这些在Technical Reference Guide里都有的

我要的是完整的配置过程，可以响应来自外中断的配置方式，包括GPIO的焊版，输入输出模式，上升沿还是下降沿检测，中断使能，不是你这种随随便便挑两点讲，请给一个完整的配置方案好么？

兄弟，你的要求还真不少呀，还要包括GPIO的焊板， 输入输入出模式。 上升还是下降沿。
正好这做两在做这一块东西，就满足你一下吧
测试，比如选两个GPIO引脚 分别是gpio_14, gpio_15，假如我们用gpio_14来输出一个脉冲，gpio_15来检测并生成成一个上升沿触发的中断。（这个只是一个简单测试，如果你需要外面来信号，请自己保证信号已经消抖动）
1，  这两个引脚中1K电阻连接起来。（不连电阻也行，不过连电阻放心一些）
2，  用TI的PINMUX UTILITY那个工具，算出PADCONF寄存器的设置。
3，  gpio_14 gpio_15都属于gpio_bank1 复位GPIO1_SYSCONFIG     48310010[1]位操作写入1
4，  GPIO1_OE寄存器0x48310034,  第14位写0设gpio_14为输出，第15位写1设置gpio_15为输入。
5，  注册一个GPIO15的中断服务程序
6，  GPIO_RISINGDETECT 0x48310048第15位写1，开放上升尚触发
7，  如果你是在ARM下测试，写GPIO_SETIRQENABLE1 0x48310064第15位，使能gpio_15的中断。如果是在DSP下，则写GPIO_IRQENABLE2
测试，这时你可以往GPIO_SETDATAOUT写0各1,  然后在从0变到1的过程中，就应该进行你的中断程序了.

嘻嘻 谢谢大牛，早知道你就是嫌麻烦，不想写，呵呵，这个论坛真的好棒，三寸丁好人。呵呵

你好我想问一下，注册中断的中断号怎么给

好想问SYSbios下的中断设置
