zedboard学习记录.2.PS+PL 流水灯与uart

1.建立一个工程。

硬件设计

2.IP integrator -> create block desgin;Run Block Automation.

3.add IP -> AXI GPIO;ritht-click -> Costomize Blocking or double left-click，gpio 8bits leds；

3. Run Connection Automation -> select all.

4.file -> save

硬件处理

5.Tools -> Validate Design

6.right-click -> Generate Output Products;right-click -> Create HDL Wapper;

7.Generate Bitstream.

8.File -> Export Hardware;include bitstream.

9. File -> Launch SDK

接下来在SDK中写软件

10. File -> New -> App Project.

11.Next -> Hello World -> finish.

12. open -> resouce -> helloworld.c

13.写代码

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

#define LED_DELAY 10000000

void led_delay()    //times delay
{
    u32 i;
    for(i=0;i<=LED_DELAY;i++);
}

int main()
{
    init_platform();
    u32 cnt,m;
    //loop forever
    while(1){
        for(m=0;m<=8;m++){
            Xil_Out32(XPAR_AXI_GPIO_0_BASEADDR, 0x01<<m);
            led_delay();
            if(m==8){
                printf("Hello World! %ld:SUCESS!

",cnt++);
            }
        }
    }

    cleanup_platform();
    return 0;
}

14.Save.

控制出现 build finished 就编译好了。

下载与调试

15.连接zedboard与pc。两根microUSB，一根是PROG，JTAG；一根是USB转串口。上电！

16.Xlinx -> Program FPGA

17.Run -> run configurations -> run

Done！

此时板上led开始闪烁，控制台也开始打印输出。

finished！
