以下是Xilinx MicroBlaze定时器的代码示例:
```c
#include <stdio.h>
#include "platform.h"
#include "xil_printf.h"
#include "xparameters.h"
#include "xtmrctr.h"
#define TIMER_DEVICE_ID XPAR_TMRCTR_0_DEVICE_ID
#define TIMER_COUNTER_0 0
XTmrCtr TimerCounterInst;
int main()
{
init_platform();
int Status;
u32 Value;
Status = XTmrCtr_Initialize(&TimerCounterInst, TIMER_DEVICE_ID);
if (Status != XST_SUCCESS) {
xil_printf("Timer init failed\n\r");
return XST_FAILURE;
}
XTmrCtr_SetResetValue(&TimerCounterInst, TIMER_COUNTER_0, 0xFFFFFFFF);
XTmrCtr_Start(&TimerCounterInst, TIMER_COUNTER_0);
while (1) {
Value = XTmrCtr_GetValue(&TimerCounterInst, TIMER_COUNTER_0);
xil_printf("Timer value: %d\n\r", Value);
}
cleanup_platform();
return 0;
}
```
该代码使用了Xilinx提供的XTmrCtr库来控制MicroBlaze的定时器。在初始化定时器后,使用`XTmrCtr_SetResetValue`函数设置定时器的重置值,然后使用`XTmrCtr_Start`函数启动定时器。在while循环中,使用`XTmrCtr_GetValue`函数获取当前定时器的值,并输出到终端。
