以下是使用STM32CubeMX编写MX30102测试心率血氧的程序的步骤:
1. 打开STM32CubeMX软件,选择对应的芯片型号stm32f407zgt6,创建一个新工程。
2. 在Pinout & Configuration选项卡中,配置I2C外设,并设置I2C的时钟频率和地址(MX30102的默认地址为0x57)。
3. 在中断配置中,启用I2C的中断。
4. 在Clock Configuration选项卡中,选择合适的时钟源和频率。
5. 在Project Manager选项卡中,生成代码并打开工程。
6. 在工程中添加MX30102的驱动程序(可以从官方网站上下载),并将其添加到工程中。
7. 在main函数中初始化MX30102,并设置心率和血氧数据的输出格式。
8. 在主循环中,使用I2C读取MX30102的心率和血氧数据,并将其输出到终端窗口。
以下是一个简单的示例代码(供参考):
```c
#include "main.h"
#include "mx30102.h"
I2C_HandleTypeDef hi2c1;
void SystemClock_Config(void);

MX_I2C1_Init();
MX30102_Init(&hi2c1);
MX30102_SetOutputFormat(&hi2c1, MX30102_FORMAT_SPO2_HR);
while (1)
{
uint16_t spo2, hr;
MX30102_ReadSpo2(&hi2c1, &spo2);
MX30102_ReadHR(&hi2c1, &hr);
printf("SPO2: %d, HR: %d\n", spo2, hr);
HAL_Delay(1000);
}
}

}

if (HAL_I2C_Init(&hi2c1) != HAL_OK)
{

}
}
void Error_Handler(void)
