压敏传感器感知200g重物后给stm32f103rct6传递参数的代码

假设您已经连接好了压敏传感器到STM32F103RCT6的ADC通道，并且已经按照压敏传感器的数据手册设置好了相应的电路和参数，那么下面是一个示例代码，可以读取ADC通道的值并通过串口发送给PC端：

#include "stm32f10x.h"
#include <stdio.h>

void USART1_Init(void)
{
    GPIO_InitTypeDef GPIO_InitStructure;
    USART_InitTypeDef USART_InitStructure;

    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA | RCC_APB2Periph_USART1, ENABLE);

    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_9;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_10;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    USART_InitStructure.USART_BaudRate = 115200;
    USART_InitStructure.USART_WordLength = USART_WordLength_8b;
    USART_InitStructure.USART_StopBits = USART_StopBits_1;
    USART_InitStructure.USART_Parity = USART_Parity_No;
    USART_InitStructure.USART_HardwareFlowControl = USART_HardwareFlowControl_None;
    USART_InitStructure.USART_Mode = USART_Mode_Rx | USART_Mode_Tx;
    USART_Init(USART1, &USART_InitStructure);

    USART_Cmd(USART1, ENABLE);
}

void ADC1_Init(void)
{
    GPIO_InitTypeDef GPIO_InitStructure;
    ADC_InitTypeDef ADC_InitStructure;

    RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1 | RCC_APB2Periph_GPIOA, ENABLE);

    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AIN;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    ADC_InitStructure.ADC_Mode = ADC_Mode_Independent;
    ADC_InitStructure.ADC_ScanConvMode = DISABLE;
    ADC_InitStructure.ADC_ContinuousConvMode = ENABLE;
    ADC_InitStructure.ADC_ExternalTrigConv = ADC_ExternalTrigConv_None;
    ADC_InitStructure.ADC_DataAlign = ADC_DataAlign_Right;
    ADC_InitStructure.ADC_NbrOfChannel = 1;
    ADC_Init(ADC1, &ADC_InitStructure);

    ADC_Cmd(ADC1, ENABLE);

    ADC_ResetCalibration(ADC1);
    while (ADC_GetResetCalibrationStatus(ADC1));

    ADC_StartCalibration(ADC1);
    while (ADC_GetCalibrationStatus(ADC1));
}

float getVoltage(uint16_t adc_value)
{
    return (float)adc_value * 3.3 / 4095;
}

int main(void)
{
    USART1_Init();
    ADC1_Init();

    uint16_t adc_value;
    float voltage;

    while (1)
    {
        ADC_SoftwareStartConvCmd(ADC1, ENABLE);
        while (!ADC_GetFlagStatus(ADC1, ADC_FLAG_EOC));
        adc_value = ADC_GetConversionValue(ADC1);
        voltage = getVoltage(adc_value);

        if (voltage > 1.5)
        {
            printf("Object detected!\r\n");
        }
        else
        {
            printf("No object detected.\r\n");
        }
    }
}

这个示例代码使用了USART1和ADC1，如果您使用的是其它串口和ADC通道，需要做相应的修改。ADC通道的值通过`getVoltage()`函数转换成电压值，然后判断电压是否大于1.5V，如果是，则说明有物体被检测到了。
