我正在使用 Cortex M3、Stellaris® LM3S6965 评估板。如果我按下一个按钮，我正在尝试打开一个 LED。但是在构建时它总是给我一个错误。

在程序中，我基本上检查按钮的状态，然后启用 LED。我是新手，我尝试搜索，但我真的找不到有用的东西。

非常感谢

我现在的程序

#include "inc/hw_types.h"
#include "inc/hw_memmap.h"
#include "driverlib/sysctl.h"
#include "driverlib/gpio.h"

char rawInputActive(void);

int main(void)
{
    volatile unsigned long ulLoop;

    /* Enable all the GPIO ports that I use*/
    SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOF);
    SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOE);

    /* Config the pins (input, output,..)*/
    GPIOPinTypeGPIOInput(GPIO_PORTF_BASE, GPIO_PIN_1);  // select
    GPIOPinTypeGPIOInput(GPIO_PORTE_BASE, GPIO_PIN_0);  // up
    GPIOPinTypeGPIOInput(GPIO_PORTE_BASE, GPIO_PIN_1);  // down
    GPIOPinTypeGPIOInput(GPIO_PORTE_BASE, GPIO_PIN_2);  // left
    GPIOPinTypeGPIOInput(GPIO_PORTE_BASE, GPIO_PIN_3);  // right

    GPIOPinTypeGPIOOutput(GPIO_PORTF_BASE, GPIO_PIN_0); // led
    GPIOPadConfigSet(GPIO_PORTF_BASE,GPIO_PIN_1,GPIO_STRENGTH_2MA,GPIO_PIN_TYPE_STD_WPU);

    /* Enable the clock for the GPIO ports.*/
    SysCtlClockSet(SYSCTL_SYSDIV_1 | SYSCTL_USE_OSC | SYSCTL_OSC_MAIN |
                       SYSCTL_XTAL_8MHZ);


    while(1)
    {
        volatile int iDelay;
        volatile int read;

        if(GPIOPinRead(GPIO_PORTF_BASE,GPIO_PIN_1) == 0){
            GPIOPinWrite(GPIO_PORTF_BASE, GPIO_PIN_0, GPIO_PIN_0); // Led select
            //ret |= 1;
            for(iDelay = 0; iDelay < 3000; iDelay++);
            GPIOPinWrite(GPIO_PORTF_BASE, GPIO_PIN_0, ~GPIO_PIN_0);
            while(GPIOPinRead(GPIO_PORTF_BASE,GPIO_PIN_1) == 0){}
            for(iDelay = 0; iDelay < 3000; iDelay++);
        }

    }
}

我在构建时遇到的错误。

您需要添加-I lm3slib到您的编译器标志。这告诉编译器查看该目录，该目录似乎是文件所在的位置。
