器件型号：DRA718

工具/软件：TI-RTOS

你(们)好

现在，我需要使用 GPIO (GPIO7) 来检测 来自外部设备的信号变化。

我将其配置为在检测下降沿模式时工作。

(1)  配置 GPIO_OE  reg 以禁用 GPIO 输出(启用 GPIO 输入)。

(2) 配置  GPIO_FAULINGDETECT  寄存器以启用下降检测。

(3) 配置 GPIO_IRQSTATUS_SET_0寄存器以启用 GPIO 中断。

但我将 sinciagle-gpio 更改为 pio，GPIO_IRQSTATUS_RAW_0仍然为零。  我无法从 GPIO 获取中断。

请看一下，我还应该做些什么来启用中断？

    您好！

    您能否查看该示例 \packages/ti\cSL\examples\gpio\gpio_interrupt\main.c、并查看它是否适合您。
    如果您未使用 Processor SDK、则 Vision 可以共享寄存器 GPIO_OE、GPIO_FAULINGDETECT 和 GPIO_IRQSTATUS_SET_0的值。

    此致、

    你(们)好
    我不使用 Vision SDK。 我转储了下面的 GPIO7寄存器、请看一下。 Thx。

    你(们)好
    我解决了这个问题。
    DEBUG_HW_RD_REG：Addr = 0x4805103c 值= 0xb80 "值不正确、我们发现 DSP 上的 GPIO 功能与内核中的 GPIO 配置冲突。 我们删除了内核中的配置，现在 GPIO 中断运行良好。
