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

 

 1 #include 
 2 #include "platform.h"
 3 #include "xil_printf.h"
 4 #include "xparameters.h"
 5 #include "xgpio.h"
 6 
 7 #define LED_DELAY 10000000
 8 
 9 void led_delay()    //times delay
10 {
11     u32 i;
12     for(i=0;i<=LED_DELAY;i++);
13 }
14 
15 int main()
16 {
17     init_platform();
18     u32 cnt,m;
19     //loop forever
20     while(1){
21         for(m=0;m<=8;m++){
22             Xil_Out32(XPAR_AXI_GPIO_0_BASEADDR, 0x01<<m);
23             led_delay();
24             if(m==8){
25                 printf("Hello World! %ld:SUCESS!\n\r",cnt++);
26             }
27         }
28     }
29 
30     cleanup_platform();
31     return 0;
32 }

 

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！
