入门第五步——I2C通信

由于I2C通信是单片机和I2C模块通信,如果不借用逻辑分析仪之类的工具的话,很难观测到数据的传输(考虑到初入行,没有能力购买逻辑分析仪),正好前面我们已经学习了UART通信,本次教程将通过UART串口来打印写入和读出的数据。由于我采用的是低功耗模块,所以为了芯片的最大化利用,我将采用低功耗模式来编程,UART和I2C将通过中断的方式来读写数据。另外本次采用的I2C模块是MB85RC04非易失铁电寄存器。

首先我们看一下这个寄存器的技术手册,查一下他的器件地址和通信流程。
华大单片机教程_第2张图片
从这张图可以看出,该寄存器的器件地址为1010XXX(),即AX(),这个括号代表写或者读。大部分器件是0写1读,这个具体得看器件手册,我这个是0写1读。另外考虑到实际的工作需求,我们采用页写和页读,这个具体的也需要查看器件手册是怎么规定的。看下图
华大单片机教程_第3张图片
这个是写多个数据,在实际项目中写一个数据的还是很少见的。
华大单片机教程_第4张图片
这个是顺序读,简单概括也就是读多个数据,且按照给定的读的地址依次往后读取给定的长度。

话说回来再讲一下通信原理:I2C 总线使用连接设备的"SCL"(串行时钟总线)和"SDA"(串行数据总线)来传送信息。主机在 SCL线上输出串行时钟信号,数据在 SDA 线上进行传输,每传输一个字节(最高位 MSB 开始传输),后面跟随一个应答位。一个 SCL 时钟脉冲传输一个数据位。通常标准 I2C 传输协议包含四个部分:起始(S)或重复起始信号(Sr),从机地址及读写位,传输数据,停止信号§。

其实I2C的通信原理并不复杂,就是上面这个流程,主机发一次消息,从机回一次消息,不回复表示没有从机响应,就结束通信或者重新发起。
讲到这里,我们还需要了解一下华大单片机的I2C状态码。看下图

今天我们用到的是主发送和主接收。
下面开始写代码。
新建一个App_I2c.c和.h

/**

 ** \brief  I2C初始化函数

 ** \return 无返回值
 **	
 **	采用硬件I2C1,传输时钟为PCLK,速率为标准速率100KHZ
 ** 
 ******************************************************************************/

#include "App_I2c_Init.h"

///< I2C 模块配置
void App_I2c_Init(void)
{
    stc_i2c_cfg_t stcI2cCfg;

    DDL_ZERO_STRUCT(stcI2cCfg);                            ///< 初始化结构体变量的值为0
    
    Sysctrl_SetPeripheralGate(SysctrlPeripheralI2c1,TRUE); ///< 开启I2C1时钟门控      

    stcI2cCfg.u32Pclk = Sysctrl_GetPClkFreq();  ///< 获取PCLK时钟
    stcI2cCfg.u32Baud = 100000;                 ///< 100KHz
    stcI2cCfg.enMode = I2cMasterMode;           ///< 主机模式
    stcI2cCfg.u8SlaveAddr = 0x55;               ///< 从地址,主模式无效
    stcI2cCfg.bGc = FALSE;                      ///< 广播地址应答使能关闭
    I2C_Init(M0P_I2C1,&stcI2cCfg);              ///< 模块初始化
    
    EnableNvic(I2C1_IRQn, IrqLevel3, TRUE);     ///< 系统中断使能
}

.h就是包含一下头文件和外部声明,这需要在初始化头文件里面调用初始化。
中断函数里面需要添加I2C中断,考虑到我们既写又读,再加上作为初学者,我们分开写函数更好,方便自己理解。
写一个I2C_PageWrite()函数和I2C_PageRead()函数,写到这我们是不是需要一个变量来说明我们是写操作还是读操作,那我们在这规定一下我们整个程序的一个流程。看下图

华大单片机教程_第8张图片
研究这个图,我们可以发现一个问题,写的过程中我们怎么知道数据是否写成功了?改进一下,我们写完就读,然后和写进去的数据进行比较,如果一样就返回0x01,不一样就返回0x00,在读过程我们也判断一下。
华大单片机教程_第9张图片
这个流程就比较完美了,写完了先验证是否真的写入。下面将流程变为现实。

过程慢慢描述进度会变慢,我这里就不多赘述,看完整代码。
