Hi All，
最近使用Cypress CY3065学习GPIO操作。现在结果是基本的控制IO输出，和非中断输入读取电平是OK的。但中断输入却一直无法触发。不知道问题出在哪？麻烦坛友高人指点一二。下面是CX3的中断配置！
CyU3PGpioClock_t gpioClock;
/* Init the GPIO module */
gpioClock.fastClkDiv = 2;
gpioClock.slowClkDiv = 0;
gpioClock.simpleDiv = CY_U3P_GPIO_SIMPLE_DIV_BY_2;
gpioClock.clkSrc = CY_U3P_SYS_CLK;
gpioClock.halfDiv = 0;
status = CyU3PGpioInit(&gpioClock, CyCX3AppGpioCB);
if( status != CY_U3P_SUCCESS)
{
CyU3PDebugPrint (4, "\n\rAppInit:GPIOInit Err = 0x%x",status);
CyCx3AppErrorHandler(status);
}
status = CyU3PDeviceGpioOverride(20, CyTrue);
if(status != 0)
{
CyU3PDebugPrint (4, "GPIO Override failed, Error Code = %d\n",status);
CyCx3AppErrorHandler (status);
}
gpioConfig.outValue = CyFalse; //默认输出低电平
gpioConfig.driveLowEn = CyFalse; //不允许输出低
gpioConfig.driveHighEn = CyFalse; //不允许输出高
gpioConfig.inputEn = CyTrue; //输入使能
gpioConfig.intrMode = CY_U3P_GPIO_INTR_POS_EDGE;
status = CyU3PGpioSetSimpleConfig (20, &gpioConfig);
if (status != CY_U3P_SUCCESS)
{
CyU3PDebugPrint (4, "GPIO Set Config Error, Error Code = %d\n", status);
CyCx3AppErrorHandler (status);
}
