以下是使用stm32c8t6和ad8232测量心率的示例程序：

}

}

void USART_SendChar(char ch)

void delay_ms(u16 nms)

}

void USART1_IRQHandler(void)
{
    if (USART_GetITStatus(USART1, USART_IT_TXE) != RESET)

    }
}

该程序使用ADC1通道0读取AD8232传感器输出的模拟电压。读取完成后，使用printf函数在串口上输出测量获得的心率值。程序使用了一个简单的delay_ms函数来实现延时。在主函数中，while循环中的延时时间为1秒。在USART_Configuration函数中，我们使用USART1模块来初始化串口。USART_SendChar函数用于发送一个字符到串口上。在USART1_IRQHandler函数中，我们使用了USART_IT_TXE中断来确认数据是否发送成功。

请注意，此示例程序可能需要根据您的具体电路和传感器进行调整。
