嵌入式实验，cortex-a9电阻器若阻值大于10则灯亮蜂鸣器响，不然则灯灭蜂鸣器停

这个问题需要您编写嵌入式程序来实现。以下是一个可能的程序代码示例，可以实现您所描述的功能：

#include <stdio.h>
#include "platform.h"
#include "xil_printf.h"
#include "xparameters.h"
#include "xgpio.h"

#define GPIO_DEVICE_ID XPAR_AXI_GPIO_0_DEVICE_ID
#define LED_CHANNEL 1
#define BUZZER_CHANNEL 2
#define RESISTOR_CHANNEL 1

XGpio gpio;

int main()
{
    init_platform();

    int status = XGpio_Initialize(&gpio, GPIO_DEVICE_ID);
    if (status != XST_SUCCESS) {
        xil_printf("Error initializing GPIO.\n");
        return XST_FAILURE;
    }

    XGpio_SetDataDirection(&gpio, LED_CHANNEL, 0x0); // set LED channel as output
    XGpio_SetDataDirection(&gpio, BUZZER_CHANNEL, 0x0); // set Buzzer channel as output
    XGpio_SetDataDirection(&gpio, RESISTOR_CHANNEL, 0x1); // set Resistor channel as input

    while (1) {
        u32 resistor_value = XGpio_DiscreteRead(&gpio, RESISTOR_CHANNEL);

        if (resistor_value > 10) {
            XGpio_DiscreteWrite(&gpio, LED_CHANNEL, 0x1); // turn on LED
            XGpio_DiscreteWrite(&gpio, BUZZER_CHANNEL, 0x1); // turn on buzzer
        } else {
            XGpio_DiscreteWrite(&gpio, LED_CHANNEL, 0x0); // turn off LED
            XGpio_DiscreteWrite(&gpio, BUZZER_CHANNEL, 0x0); // turn off buzzer
        }
    }

    cleanup_platform();
    return 0;
}

这个程序可以通过 AXI GPIO 控制 LED 和蜂鸣器的开关状态，并且读取电阻器的输入值。如果电阻器的值大于 10，则 LED 亮起并且蜂鸣器响，否则 LED 熄灭并且蜂鸣器停止。注意，这个代码示例仅供参考，请根据实际情况进行修改和调试。
