概述

本章STM32CUBEMX配置STM32F103，并且在GD32F303中进行开发，同时通过开发板内进行验证。 使用IIC进行驱动SSD1306的12864OLED。 最近在弄ST和GD的课程，需要GD样片的可以加群申请：615061293 。

生成例程

这里准备了自己绘制的开发板进行验证。查看原理图，PB8和PB9设置为开发板的IIC。

配置时钟树

配置时钟为64M。

IIC配置

本次实验使用的IIC与显示屏通信，配置如下。

OLED

查看文档可以知道地址为b0111100或者b0111101，当R/W位置写0的时候，才能进行写的操作，那么地址默认为0x78(b01111000)或者0x7A(b01111010)

参考程序

这里使用0.96OLED显示屏_STM32F103C8_IIC_V1.0来进行移植查看工程可以知道主要是有3个文件来进行OLED的驱动，移入OLE.h .c 、oledfont.h 、 bmp.h 移入文件之后要注意导入C文件。

删除没有用的头文件 删除sys.h文件

删除delay.h文件

可以查看stdint.h

在oled.h中添加u8 u32定义 也可以直接修改

typedef unsigned          char u8;

typedef unsigned           int u32;

先把oled.h添加主程序中。

查看oled.h，可以看到IIC定义，同时也是模拟IIC，可以注释掉

查看oled.c，可以看到是模拟iic，这些都可以注释不要，我们使用的是iIC，不是模拟。

HAL_I2C_Mem_Write()

IIC写固定的设备写入数据。 记得导入#include 'i2c.h'

将HAL_I2C_Mem_Write函数放入oled.c中。 例如将Write_IIC_Command函数修改为HAL_I2C_Mem_Write发送方式。

向0x78设备写命令0x00的IIC_Command指令。

/**********************************************

// IIC Write Command

**********************************************/

void Write_IIC_Command(unsigned char IIC_Command)

{

//   IIC_Start();

//   Write_IIC_Byte(0x78);            //Slave address,SA0=0

//    IIC_Wait_Ack();    

//   Write_IIC_Byte(0x00);            //write command

//    IIC_Wait_Ack();    

//   Write_IIC_Byte(IIC_Command); 

//    IIC_Wait_Ack();    

//   IIC_Stop();

     HAL_I2C_Mem_Write(&hi2c1 ,0x78,0x00,I2C_MEMADD_SIZE_8BIT,&IIC_Command,1,0x100);

}

IIC写数据 向0x78设备写数据0x40的IIC_Data指令。

/**********************************************

// IIC Write Data

**********************************************/

void Write_IIC_Data(unsigned char IIC_Data)

{

//   IIC_Start();

//   Write_IIC_Byte(0x78);            //D/C#=0; R/W#=0

//    IIC_Wait_Ack();    

//   Write_IIC_Byte(0x40);            //write data

//    IIC_Wait_Ack();    

//   Write_IIC_Byte(IIC_Data);

//    IIC_Wait_Ack();    

//   IIC_Stop();

     HAL_I2C_Mem_Write(&hi2c1 ,0x78,0x40,I2C_MEMADD_SIZE_8BIT,&IIC_Data,1,0x100);

}

在oled.c中，OLED_Init初始化可以注释掉gpio初始化

在oled.c中，OLED_Init初始化中有个延时800ms。 导入

#include 'stm32f1xx_hal.h' 可以使用HAL_Delay(800);

取模

在oledfont.h中放入字库

char Hzk[][32]={
