OLED为常用的外设，主要用于显示功能，常用接口为I2C、SPI。而I2C只需要2线就可以实现，更为常见。I2C可以用软件模拟I2C以及硬件的I2C驱动。软件I2C可以灵活选择GPIO来实现，在不同的单片机中移方便，但是速度相比硬件i2c慢，占用资源多。而硬件I2C速度快，占用资源小，但是硬件I2C需要指的IO，而且在有些单片机硬件i2c的兼容性不是很好，移植性差。IO的选取，这次移植为硬件i2c驱动OLED屏。SDA选取PA10，SCL选取PA1。
【开发环境】
这次选用的开发环境为ccs 12.5为开发环境。

原先我开发的环境为keil版本，但是由于例程进入低功耗后，用keil下载会出现连接不上，为此我还发了一篇帖子： HYPERLINK "https://bbs.21ic.com/icview-3333184-1-1.html" 。
后面还是安装好ccs12.5后才起死回生，所以顺便就转移到ccs12.5的开发环境里面来。使用了两天后，感觉如果开发ti还是用ccs比较方便，他集成的sysconfig相比keil要方便，保存配置什么的也比keil+sysconfig来得方便。但是安装ccs需要一些耐心，一是下载安装包比较麻烦，在国内下载速度相当的慢。还有就是安装路径不能有中文等等。
【I2C驱动的配置与初始化】
配置I2C的驱动IO，MSPM0L1306这款芯片，配置i2cIO在sysconfi环境下特别的方便。我在这里是在adc12_sigle_conversion例程下添加的I2C的驱动。具体实现方便如下：
打开例程，后双击adc12_single_conversion_syscfg，打开sysconfig配置界面：
025af800a8ddbfbd08c0c94cb0b25bbc
添加i2c，按如下配置速度：
c79da6a79d94a948ba47a06bb1237b28
选择I2c的IO，SCL为PA1/2，SDA为PA10/14：
0c87410945763d71d24b2f74651cdcfa
保存后退出sysconfig，sysconfig自动更新了ti-msp-dl-config.h生成了I2C的宏定义：
80ab85337d2c9d26c4ed40d16354e1b9
在tim-msp-dl-config.c中初始化了i2c:
b7a576fbee72c13cab216157589f69ba
【移植OLED驱动】
在上面的初始化好I2C后我们就可以移植OLED的驱动到开发板上面，具体实现步骤如下：
在工程目录下面新建oled.h、oled.c、codetab.h三个空白文件。三个文件分别为oled.h为ssd1306驱动的头文件，oled.c为ssd1306的驱动c源文件，codetab.h为字库文件。
首先复制字库文件进来，代码如下：

创建oled.h头文件，在头文件中我们需要先引用ti_msp_dl_config.h这个文件,然后声明oled.c的相关功能软件，其内容如下：

  2. 

  3. #define __OLED_H__
    


  4.

现在到了最关键的ssd1306的向寄存器写入一个byte的功能，首先我们声明I2C从机（oled）地址，特别注意的是，这里我们要声明为0x3C（有些单片机，他send7bitaddress 时需要定义为0x78)，这次我移植时先定义了0x78结果发出的地址信息为0xF0后面调整为0x3c才正常。
复制
  1. #define OLED_ADDR 0x3C

然后我们构建writeByte函数。我们使用的i2c传输函数为fifo发送，其函数原型为：
复制
  1. uint16_t DL_I2C_fillControllerTXFIFO(
    


  2. 

  3. I2C_Regs *i2c, uint8_t *buffer, uint16_t count);

所以我们在向ssd1306写入一个byte的函数中首先要组建一个数组buff用于组装fifo。
复制
  1. uint8_t buff[2] = {0};
    


  2. 

  3. buff[0] = addr;
    


  4. 

  5. buff[1] = data;

然后发送时，先判断I2C是否为空闲状态：
复制
  1. /* Wait for I2C to be Idle */
    


  2. 

  3. while (!(
    


  4. 

  5. DL_I2C_getControllerStatus(I2C_0_INST) & DL_I2C_CONTROLLER_STATUS_IDLE))
    


  6. 

  7. ;

然后我们向总线发送从机地址：
复制
  1. /* Send the packet to the controller.
    


  2. 

  3. * This function will send Start + Stop automatically.
    


  4. 

  5. */
    


  6. 

  7. DL_I2C_startControllerTransfer(I2C_0_INST, OLED_ADDR,
    


  8. 

  9. DL_I2C_CONTROLLER_DIRECTION_TX, 2);

再次我们发送一个数组：
复制
  1. DL_I2C_fillControllerTXFIFO(I2C_0_INST, &buff[0], 2);

然后等待发送完成：
复制
  1. /* Poll until the Controller writes all bytes */
    


  2. 

  3. while (DL_I2C_getControllerStatus(I2C_0_INST) &
    


  4. 

  5. DL_I2C_CONTROLLER_STATUS_BUSY_BUS)
    


  6. 

  7. ;

最后我们判断是否有错误发生：
复制
  1. /* Trap if there was an error */
    


  2. 

  3. if (DL_I2C_getControllerStatus(I2C_0_INST) &
    


  4. 

  5. DL_I2C_CONTROLLER_STATUS_ERROR) {
    


  6. 

  7. /* LED will remain high if there is an error */
    


  8. 

  9. __BKPT(0);
    


  10. 

  11. }

至此我们完成了向ssd1306指定寄存器地址发送一个byte的功能，后面的函数就不需要修改，其完整代码如下：
复制
  1. #include "oled.h"
    

  2. #include "ti_msp_dl_config.h"
    

  3. #include "codetab.h"
    


  4. 

  5. #define OLED_ADDR   0x3C
    


  6. 

  7. void OLED_I2C_Init(void)
    

  8. {
    


  9. 

  10. }
    


  11. 

  12. //向OLED寄存器地址写一个byte的数据

在主函数主我们先添加oled.h的引用然后初始化OLED，清屏后向OLED写入helloworld的字符串。
复制
  1. intmain(void)
    


  2. 

  3. {
    


  4. 

  5. SYSCFG_DL_init();
    


  6. 

  7. OLED_Init();
    


  8. 

  9. OLED_CLS();
    


  10. 

  11. OLED_ShowStr(10,0,(unsignedchar*) "HELLO WORLD",2);
    


  12. 

  13. OLED_ShowStr(4,2,(unsignedchar*) "LP-MSPM0L1306",2);
    


  14. 

  15. OLED_ShowStr(0,4,(unsignedchar*) "21IC 2023-10-17",2);

【心得体会】
Ti 在开发资料上可以说是非常的丰富，提供的开发环境也是非常多，比如keil、IAR、vscode，特别是他们的家ccs，结合起来是非常的好用。
【建议】
在keil上的有些例程下载后会出现再次下载就报错的问题，这方面Ti没有在例程中提醒用户，如果遇到经验不丰富的客户会认会是器件的问题。**在例程中提醒客户，在开发调试可增加条件编译，加入一定时长的延时，避免上电就进入睡眠，而造成keil环境下载固件出错的BUG。

是的，MDK下下载出错就是这个问题导致的，换CCS下载就方便很多了。
