软件部分 ​

将先前03_RTC工程复制一份，重命名为04_OLED_BME280-I2C。

1 配置I2C ​

首先在e2s内配置I2C

序号操作
1点击界面下方标签栏中的Pins标签，进入引脚配置界面。
2在Pin Selection区域，展开Connectivity:I2C选项，选择I2C0。
3在Pin Configuration区域，将Pin Group Selection设置为_A only，Operation Mode设置为Enabled。
4勾选SDA0对应的P401引脚和SCL0对应的P400引脚。

alt text

序号操作
1在Pin Selection区域，分别选择P400和P401引脚。
2将Output type设置为n-ch open drain，把P400和P401配置成开漏输出。

alt text

序号操作
1点击界面下方标签栏中的Stacks标签，进入堆栈配置页面。
2在HAL/Common Stacks区域，点击New Stack按钮。
3在弹出菜单中，选择Connectivity选项。
4在Connectivity子菜单中，选择I2C Master (r_iic_master)。

alt text

序号操作
1在HAL/Common Stacks区域，点击选中g_i2c_master0 I2C Master (r_iic_master)。
2在下方Settings设置区域的Module g_i2c_master0 I2C Master (r_iic_master)部分，将Rate设置为Fast-mode。
3Module g_i2c_master0 I2C Master (r_iic_master)部分，设置Slave Address为0x3c。
4Module g_i2c_master0 I2C Master (r_iic_master)部分，设置Callback为iic_callback，Interrupt Priority Level为Priority 2。

这里说明一下，在移植商家给的STM32 OLED驱动库时看到屏幕地址为0x78，即 01111000，是包含读写位的（最低位）。而瑞萨这里是7位地址，不含读写位，因此要将0x78右移1位，即0x3C (0111100)。

确认上面设置没问题后，生成项目代码。

2 编写代码 ​

2.1 I2C通信相关 ​

新建i2c.c和i2c.h文件。

i2c.h:

查看代码
c
#ifndef I2C_H_
#define I2C_H_

extern volatile bool i2c_rx_complete;
extern volatile bool i2c_tx_complete;

void i2c_wait_rx();
void i2c_wait_tx();
#endif

i2c.c:

查看代码
c
#include "hal_data.h"
#include "i2c.h"

volatile bool i2c_rx_complete = false;
volatile bool i2c_tx_complete = false;
uint16_t timeout = 0;

void iic_callback(i2c_master_callback_args_t *p_args)
{
    if (p_args->event == I2C_MASTER_EVENT_RX_COMPLETE)
    {
        i2c_rx_complete = true;
    }
    else if (p_args->event == I2C_MASTER_EVENT_TX_COMPLETE)
    {
        i2c_tx_complete = true;
    }
}

void i2c_wait_tx()
{
    timeout = 1000;
    while (!i2c_tx_complete && timeout > 0)
    {
        timeout--;
    }
    i2c_tx_complete = false;
}

void i2c_wait_rx()
{
    timeout = 1000;
    while (!i2c_rx_complete && timeout > 0)
    {
        timeout--;
    }
    i2c_rx_complete = false;
}

由于瑞萨FSP库的高集成度，我只需要编写代码实现回调函数iic_callback、等待发送函数i2c_wait_tx、等待接收i2c_wait_rx函数改变标志位即可。

BME280_compensate_T_double、bme280_compensate_H_double、bme280_compensate_P_double这三个函数分别为温度、湿度、气压的补偿算法函数，借鉴了BME280官方数据手册内给出的参考代码。 bme280工作流程为

步骤内容
1上电初始化
2写入0xF2、0xF4、0xF5寄存器以设定过采样率等参数
3获取校准数据
4调用BME280_Get_Data函数，读取0xF7~0xFE寄存器的数据
5调用补偿算法函数得到人类可读的数值

注意

在写入+读取函数后记得跟1~5ms的延时，再进行下一步操作，否则会因为bme280侧的数据未准备好，有极大概率读取到错误数据或读不到数据。

TIP

最开始OLED屏幕上显示字的速度非常慢，几乎是一个字一个字地往外蹦。 解决方法是开一个显存数组OLED_GRAM ，将内容先缓存到显存数组，再调用OLED_Refresh一次性地写给OLED屏幕控制器

2.4 修改hal_entry.c ​

在hal_entry.c开头加入

查看代码
c
#include "hal_data.h"
#include "debug_bsp_uart.h"
#include "oled.h"
#include "bme280.h"
#include "rtc.h"
#include <stdio.h>

BME_Struct bme = {0, 0, 0, false};
rtc_time_t get_time;

在hal_entry函数中加入

查看代码
c

        if (rtc_flag)
        {
            g_rtc0.p_api->calendarTimeGet(&g_rtc0_ctrl, &get_time); // 获取 RTC 计数时间
            rtc_flag = 0;

            // 解析设置时间的命令 e.g: time:20250126080910
            // warning: 未添加错误纠正算法，请输入正确的时间，否则工作异常！
            if (strncmp(rx_data, "time:", 5) == 0)
            {
                time = rx_data + 5;
                set_time.tm_year = ((time[0] - '0') * 1000) + ((time[1] - '0') * 100) +
                                   ((time[2] - '0') * 10) + (time[3] - '0') - 1900;
                set_time.tm_mon = ((time[4] - '0') * 10) + (time[5] - '0') - 1;
                set_time.tm_mday = ((time[6] - '0') * 10) + (time[7] - '0');
                set_time.tm_hour = ((time[8] - '0') * 10) + (time[9] - '0');
                set_time.tm_min = ((time[10] - '0') * 10) + (time[11] - '0');
                set_time.tm_sec = ((time[12] - '0') * 10) + (time[13] - '0');
                g_rtc0.p_api->calendarTimeSet(&g_rtc0_ctrl, &set_time);
            }
            else{
                printf("若要通过串口设置时间，请输入类似time:20250126080910的字符串\n");
            }
        }
    }

这段程序实现了每1秒刷新一次OLED屏幕上的时间和温湿度气压数据，同时能从串口接收格式化的数据以设定时间。
