使用Vivado初探ZedBoard的OLED驱动

一、原理简介

Vivado版本：2016.2

OLED型号：128*32的UG-2832HSWEG04

ZedBoard的OLED部分电路原理图如下：（需要我们关心的是我用红色椭圆标注出来的3处，一共6个信号）

zedboard控制OLED的主要方法是：自己设计一个IP核，把OLED对应的6个控制引脚进行逻辑设计和约束，IP核通过AXI总线，把OLED对应的6个控制引脚和PS联系起来。通过PS编写相应的驱动程序，即可实现对OLED的控制。方案如下：

二、在Vivado中进行硬件设计

1.创建工程（板子型号选zedboard）>> Tools >> Create and Package IP

2.选择Create AXI4 Peripheral

3.更改ip名

4.一路默认，在最后一页选择Edit IP（最小得选4个寄存器实际我们只用到了一个32位寄存器中的低6位）

5.此时会建立一个临时工程，在我们修改完成后会自行删除

6.给顶层文件添加输出端口OLED，即添加如下代码：output wire [5:0] OLED

给子模块添加.OLED(OLED),

7.同样，给子模块添加输出端口OLED，即添加如下代码： output reg [5:0] OLED,

然后添加如下代码，将slv_reg0寄存器的低6位赋给OLED端口

8.保存，并在如下页面的Customization GUI中确认，所添加的输出端口是否显示出来，如果没有，在此页面顶部有会提示，点击更新一下即可

9.点击下图底部的Re-Package IP，此时软件自动关闭。可在IP catalog的下属文件夹中找到了定义的IP。（以上为创建AXI IP的基本步骤）

10.创建Block Design，名字默认。添加ZYNQ，以及自定义的myOLED_ip。点击Run Block Automation。

11.修改ZYNQ，只保留一个uart1和默认的GPIO。点击Run Connection Automation，并Regenerate Layout，最终的block设计图如下：

分配的地址如下：

12.validate design >> generate output products >> create HDL wrapper.

13.查看zedboard中OLED硬件连接原理图（我们需要用到的就是我红色椭圆标注出来的）

14.综合后，打开综合设计，在I/O Planning 视图中按原理图添加OLED端口约束管脚，这里的顺序可以随意，但一定要和后续的驱动程序相对应。

　这里给出我的约束文件代码：

set_property IOSTANDARD LVCMOS33 [get_ports {OLED[5]}]set_property IOSTANDARD LVCMOS33 [get_ports {OLED[4]}]set_property IOSTANDARD LVCMOS33 [get_ports {OLED[3]}]set_property IOSTANDARD LVCMOS33 [get_ports {OLED[2]}]set_property IOSTANDARD LVCMOS33 [get_ports {OLED[1]}]set_property IOSTANDARD LVCMOS33 [get_ports {OLED[0]}]set_property PACKAGE_PIN U12 [get_ports {OLED[5]}]set_property PACKAGE_PIN U11 [get_ports {OLED[4]}]set_property PACKAGE_PIN AA12 [get_ports {OLED[3]}]set_property PACKAGE_PIN U10 [get_ports {OLED[0]}]set_property PACKAGE_PIN U9 [get_ports {OLED[1]}]set_property PACKAGE_PIN AB12 [get_ports {OLED[2]}]

也就是说，我的引脚对应关系为：

15.生成比特流 >> export to hardware >> lanch sdk 。至此，vivado中的硬件设计就结束了。

三、在SDK中进行软件设计

1.新建工程application project >> 选择hello world模板（这里有一些自动添加进来的文件可能会用到，比如：platform.h和platform.c 如果选择空模板的话，这些文件不会被自动添加进来，目前我也不知道怎么手动添加它们）

2.新建oled.h头文件，代码如下：

/* * oled.h */#ifndef OLED_H_#define OLED_H_#include "xil_types.h" // 数据类型定义#include "xil_io.h"extern int usleep(unsigned int useconds);#define OLED_BASE_ADDR 0X43c00000 //这里根据自己vivado中分配的地址来修改#define OLED_DC 0#define OLED_RES 1#define OLED_SCLK 2#define OLED_SDIN 3#define OLED_VBAT 4#define OLED_VDD 5//Xil_Out32(OLED_BASE_ADDR,1<<i);// DC#define Set_OLED_DC (Xil_Out32(OLED_BASE_ADDR,Xil_In32(OLED_BASE_ADDR)|(1<<OLED_DC)))#define Clr_OLED_DC (Xil_Out32(OLED_BASE_ADDR,Xil_In32(OLED_BASE_ADDR)&(~(1<<OLED_DC))))// RES#define Set_OLED_RES (Xil_Out32(OLED_BASE_ADDR,Xil_In32(OLED_BASE_ADDR)|(1<<OLED_RES)))#define Clr_OLED_RES (Xil_Out32(OLED_BASE_ADDR,Xil_In32(OLED_BASE_ADDR)&(~(1<<OLED_RES))))// SCLK#define Set_OLED_SCLK (Xil_Out32(OLED_BASE_ADDR,Xil_In32(OLED_BASE_ADDR)|(1<<OLED_SCLK)))#define Clr_OLED_SCLK (Xil_Out32(OLED_BASE_ADDR,Xil_In32(OLED_BASE_ADDR)&(~(1<<OLED_SCLK))))// SDIN#define Set_OLED_SDIN (Xil_Out32(OLED_BASE_ADDR,Xil_In32(OLED_BASE_ADDR)|(1<<OLED_SDIN)))#define Clr_OLED_SDIN (Xil_Out32(OLED_BASE_ADDR,Xil_In32(OLED_BASE_ADDR)&(~(1<<OLED_SDIN))))// OLED_VBAT#define Set_OLED_VBAT (Xil_Out32(OLED_BASE_ADDR,Xil_In32(OLED_BASE_ADDR)|(1<<OLED_VBAT)))#define Clr_OLED_VBAT (Xil_Out32(OLED_BASE_ADDR,Xil_In32(OLED_BASE_ADDR)&(~(1<<OLED_VBAT))))// OLED_VDD#define Set_OLED_VDD (Xil_Out32(OLED_BASE_ADDR,Xil_In32(OLED_BASE_ADDR)|(1<<OLED_VDD)))#define Clr_OLED_VDD (Xil_Out32(OLED_BASE_ADDR,Xil_In32(OLED_BASE_ADDR)&(~(1<<OLED_VDD))))//OLED控制用函数void write_data(u8 data);void write_cmd(u8 data);void OLED_Display_On(void);void OLED_Display_Off(void);void OLED_Refresh_Gram(void);void OLED_Init(void);void OLED_Clear(void);void OLED_DrawPoint(u8 x,u8 y,u8 t);void OLED_Fill(u8 x1,u8 y1,u8 x2,u8 y2,u8 dot);void OLED_ShowChar(u8 x,u8 y,u8 chr,u8 size,u8 mode);void OLED_ShowNum(u8 x,u8 y,u32 num,u8 len,u8 size);void OLED_ShowString(u8 x,u8 y,const u8 *p);#endif /* OLED_H_ */

3.新建oled.c源文件，代码如下：

5.修改hello world主程序，代码如下：

#include <stdio.h>//#include "platform.h"#include "xil_types.h"#include "xparameters.h"//#include "xgpiops.h"//#include "xil_io.h"#include "oled.h"int main(void){ print("##### Application Starts #####\n\r"); OLED_Init();while(1){ OLED_ShowString(0,0, "Hello LengWaWa"); OLED_Refresh_Gram(); sleep(1); OLED_Clear();//清屏，否则如果后续显示的长度比较短的话，就不会完全更新为新的数据，有拖尾 OLED_ShowNum(0,0,123456789,9,16); OLED_Refresh_Gram(); sleep(1);　　} return 0;}
