硬件准备

首先需要准备一个开发板，这里我准备的是芯片型号R7FAM2AD3CFP的开发板：

RA4M2

新建工程

RA4M2

工程模板

RA4M2

保存工程路径

RA4M2

芯片配置

本文中使用R7FA4M2AD3CFP来进行演示。

RA4M2

工程模板选择

RA4M2

时钟设置

开发板上的外部高速晶振为12M.

RA4M2 需要修改XTAL为12M。

RA4M2

IIC属性配置

查看手册，可以得知OLED的IIC地址为“b0111100” or “b0111101”，即0x3c或者0x3d。

RA4M2

在OLED的模块中，丝印上面写的地址是0x78(b0111 1000)或者0x7a(b0111 1010)，是因为加了一位RW位，因为一般只要发送数据让屏幕进行显示。

RA4M2

IIC配置

配置RA4M2的I2C接口，使其作为I2C master进行通信。查看开发板原理图，对应的IIC为P408和P409。

RA4M2

点击Stacks->New Stack->Connectivity -> I2C Master(r_sci_i2c)。

RA4M2

设置IIC的配置，需要注意从机的地址，在stm32等程序中写的是0x78,但是这里的地址位数是7位，故需要右移一位，变成0x3c。

RA4M2

R_SCI_I2C_Open()函数原型

RA4M2

R_SCI_I2C_Open()函数为执行IIC初始化，开启配置如下所示。

/* Initialize the I2C module */
       err = R_SCI_I2C_Open(&g_i2c3_ctrl, &g_i2c3_cfg);
       /* Handle any errors. This function should be defined by the user. */
       assert(FSP_SUCCESS == err);

R_SCI_I2C_Write()函数原型

RA4M2

R_SCI_I2C_Write()函数是向IIC设备中写入数据，写入格式如下所示。

err = R_SCI_I2C_Write(&g_i2c_device_ctrl_1, &g_i2c_tx_buffer[0], I2C_BUFFER_SIZE_BYTES, false);
    assert(FSP_SUCCESS == err);

sci_i2c_master_callback()回调函数

对于数据是否发送完毕，可以查看是否获取到I2C_MASTER_EVENT_TX_COMPLETE字段。

RA4M2

/* Callback function */
i2c_master_event_t i2c_event = I2C_MASTER_EVENT_ABORTED;
void sci_i2c_master_callback(i2c_master_callback_args_t *p_args)
{
    i2c_event = I2C_MASTER_EVENT_ABORTED;
    if (NULL != p_args)
    {
        /* capture callback event for validating the i2c transfer event*/
        i2c_event = p_args- >event;
    }
}

控制与发送数据

对于发送数据，可以使用R_SCI_I2C_Write()函数，对于是否发送完毕，可以判断I2C_MASTER_EVENT_TX_COMPLETE != i2c_event，并且引入超时机制。向0x3c设备写命令0x00的IIC_Command指令。

/**********************************************
 IIC Write Command
**********************************************/
void Write_IIC_Command(unsigned char IIC_Command)
{

    uint8_t ii[2]={0x00,0x00};
    ii[1] = IIC_Command;



    err = R_SCI_I2C_Write(&g_i2c3_ctrl, ii, 0x02, true);
           assert(FSP_SUCCESS == err);
           /* Since there is nothing else to do, block until Callback triggers*/
           //while ((I2C_MASTER_EVENT_TX_COMPLETE != i2c_event) && timeout_ms)
           while ((I2C_MASTER_EVENT_TX_COMPLETE != i2c_event) && timeout_ms >0)
           {
               R_BSP_SoftwareDelay(100U, BSP_DELAY_UNITS_MICROSECONDS);
               timeout_ms--;
           }
           if (I2C_MASTER_EVENT_ABORTED == i2c_event)
           {
               __BKPT(0);
           }
           /* Read data back from the I2C slave */
           i2c_event = I2C_MASTER_EVENT_ABORTED;
           timeout_ms           = 100000;
}

IIC写数据向0x3c设备写数据0x40的IIC_Data指令。

/**********************************************
// IIC Write Data
**********************************************/
void Write_IIC_Data(unsigned char IIC_Data)
{


    uint8_t ii[2]={0x40,0x00};
    ii[0] = 0x40;
    ii[1] = IIC_Data;
    err = R_SCI_I2C_Write(&g_i2c3_ctrl, ii, 0x02, true);
           assert(FSP_SUCCESS == err);
           /* Since there is nothing else to do, block until Callback triggers*/
           //while ((I2C_MASTER_EVENT_TX_COMPLETE != i2c_event) && timeout_ms)
           while ((I2C_MASTER_EVENT_TX_COMPLETE != i2c_event) && timeout_ms >0)
           {
               R_BSP_SoftwareDelay(100U, BSP_DELAY_UNITS_MICROSECONDS);
               timeout_ms--;
           }
           if (I2C_MASTER_EVENT_ABORTED == i2c_event)
           {
               __BKPT(0);
           }
           /* Read data back from the I2C slave */
           i2c_event = I2C_MASTER_EVENT_ABORTED;
           timeout_ms           = 100000;

}

驱动代码

若需要让OLED显示字符或者图片，需要添加驱动文件，添加方式如下。

RA4M2

主要需要添加如下四个文件。 oled.c:该文件包含控制OLED屏幕并与之通信的主要代码。具有初始化屏幕、绘制图形和文本以及更新显示的函数。 oled.h:这个头文件可以声明函数原型和任何在oled.c文件中使用的常量或变量。 bmp.h:该文件包含在OLED屏幕上呈现BMP图像文件的代码。 oledfont.h:这个文件包含在OLED屏幕上渲染自定义字体的代码，或者可能声明一个用于显示文本的字体表。这四个文件附录在最后。

字符取模

由于单片机的flash比较吃紧，所以要显示汉字需要先进行取模。首先需要设置为字符模式。

RA4M2

取模软件设置。

RA4M2

设置完之后就可以取自己想要汉字的编码，输入完毕点击生成字模即可。

RA4M2

在oledfont.h中放入字库。

RA4M2

字体大小只有2个。

RA4M2

在hal_entry.c中添加显示。

/* Initialize the I2C module */
    err = R_SCI_I2C_Open(&g_i2c3_ctrl, &g_i2c3_cfg);
    /* Handle any errors. This function should be defined by the user. */
    assert(FSP_SUCCESS == err);

    OLED_Init();            //初始化OLED
    OLED_Clear()    ;
    OLED_ShowCHinese(0,0,0);//记
    OLED_ShowCHinese(16,0,1);//帖

    OLED_ShowNum(0,2,2023,4,16);//显示ASCII字符的码值
    OLED_ShowCHinese(32,2,2);//中文字- >年
    OLED_ShowNum(48,2,1,2,16);//显示ASCII字符的码值
    OLED_ShowCHinese(64,2,3);//中文字- >月
    OLED_ShowNum(80,2,31,2,16);//显示ASCII字符的码值
    OLED_ShowCHinese(96,2,4);//中文字- >日
    OLED_ShowString(0,4,"ZXY",12);
    OLED_ShowString(0,6,"RA4M2",16);

显示结果如下所示。

RA4M2

图片取模

设置为图形模式。

RA4M2

格式设置。

RA4M2

选择需要打开的文件。

RA4M2

打开的文件必须为bmp文件。

RA4M2

选择生成字模。

RA4M2

图片数据放在bmp.h中。

RA4M2

显示图片

/* Initialize the I2C module */
    err = R_SCI_I2C_Open(&g_i2c3_ctrl, &g_i2c3_cfg);
    /* Handle any errors. This function should be defined by the user. */
    assert(FSP_SUCCESS == err);

    OLED_ShowString(0,6,"RA4M2",16);

    /* Wait for minimum time required between transfers. */
    R_BSP_SoftwareDelay(2, BSP_DELAY_UNITS_SECONDS);
    OLED_Clear();
    OLED_DrawBMP(0,0,64,8,BMP1); //图片显示(图片显示慎用，生成的字表较大，会占用较多空间，FLASH空间8K以下慎用)
