前言

之前发布了一篇硬件I2C的0.96' OLED驱动代码，这次就添加一篇硬件SPI的驱动代码。

其实改动的代码不多，对下面两个写命令和写数据的函数稍加改动即可。

void OLED_WR_DATA(uint8_t data) 和 void OLED_WR_CMD(uint8_t cmd)

一、OLED驱动的基本功能

跟I2C那篇驱动代码的功能一致，这里再叙述一下。。。

1.可以正反相显示8X16，6x8的字符，数字，字符串
2.可以正反相显示16X16的汉字
3.可以正反相显示任意大小的图像
4.全屏水平滚动播放，部分屏幕水平滚动播放，全屏垂直水平滚动播放
5. 屏幕亮度调节，屏幕内容取反显示
6. 可以正反相显示8X16，6x8的正负浮点数

二、CubeMX中的设置

2.1. 配置时钟树

（1）点击RCC 开启HSE，并选择RC或晶体作为时钟源

（2）配置时钟树

最终最右侧显示为

2.2. 配置硬件SPI

需要配置的参数如下：

*********************************************************
*   引脚定义：                                         
*   OLED_CS  OLED_RES  OLED_DC   ：OUTPUT  Output push pull
*********************************************************
*   SPI定义：                                          
*   Mode:Transmit only Master                          
*   Hardware Nss Signal:Disable                        
*   Data Size : 8Bits                                  
*   First Bit : MSB First                              
*   CPOL : Low                                         
*   CPHA : 1 Edge	 
*********************************************************

（1）选择SPI1；

将模式选择为 Transmit only Master （主机发送，从机接收）；Hardware Nss Signal: Disable ；

（2）SPI参数设定

其中时钟的预分频系数Prescaler可以设置的小一些，这样对应的波特率Baud Rate 就会比较大，相应的直观感受是OLED刷新的速度很快，屏闪感受变小。

（3）GPIO配置

PB0、PB1、PB10 都设置为 初始低电平，推挽输出，无上下拉电阻，高速输出 的模式

（4）烧录选SWD

2.3. 接线以及最终管脚图

********************************************************
*   接线：                                             
*   GND ---> GND                                       
*   VCC ---> 3.3V                                      
*   DO  ---> SPI_SCK       PA5                            
*   D1  ---> SPI_MOSI      PA7                            
*   RES ---> OLED_RES      PB0                            
*   DC  ---> OLED_DC       PB1                            
*   CS  ---> OLED_CS       PB10                            
*                                                                                                    
********************************************************

三、代码

3.1. oled.c

>注：
> 1.上图中 Set Charge Pump （设置电荷泵）设置为0x8D,0x10即关闭了电荷泵;而程序中笔者开启了电荷泵，故设置为0x8D,0x14。而且把这一步放置在了初始化的最后。
> 2.笔者的初始化程序在对比度设置（红色字体处），预充电持续时间等数值大小上与上图不同，其实只要初始化思路一致，这些差异不会影响OLED的使用，这些个性化设置还需好好参读芯片手册**

 OLED_ShowNum(48,7,77,2,12, 1);//反相显示2位6X8数字“77”
 OLED_DrawBMP(90,0,122, 4,BMP1,0);//正相显示图片BMP1
 OLED_DrawBMP(90,4,122, 8,BMP1,1);//反相显示图片BMP1
 
 OLED_HorizontalShift(0x26);//全屏水平向右滚动播放

//显示正负浮点数的代码
//  float num1=-231.24;
//  float num2=23.375;

//OLED_ShowString(0,0,"Show Decimal",12,0);
//OLED_Showdecimal(0,4,num1,3,2,12, 0);
//OLED_Showdecimal(0,6,num2,2,3,16, 1);

 
  /* USER CODE END 2 */

总结

以上就是7针0.96寸OLED的HAL库版本的代码，全部按我这个操作100%一次点亮OLED屏，接下来我还会分享软件I2C、软件SPI以及简易OLED多级菜单。

图像风格转换之 CUT 论文解读与感想

Contrastive Learning for Unpaired Image-to-Image Translation（CUT）是发布于2020年ECCV的一篇关于图像风格转换的文章。本文最大的特点就是将目前大热的对比学习应用到了图像风格转换问题上来，实现了一种轻量级的图像风格转换模型，并且本文可以进一步实现单张图片之间的风格转换。文章切入点无配对图像风格转换领域近些年来最成功和最经典的模型无疑
