利用stm32写称重传感器代码

由于不了解具体的称重传感器型号和接口方式,以下是一份基于ADC采集的通用代码,需要根据具体情况进行适当修改。
```
#include "stm32f10x.h"
void ADC1_Init(void);
u16 ADC1_GetValue(void);
void Delay(__IO uint32_t nCount);
int main(void)
{
u16 adc_value;
float weight;
ADC1_Init();
while (1)
{
adc_value = ADC1_GetValue();
weight = (float)adc_value / 4096 * 3.3 * 1000 / 1.5; // 根据电压与电阻值计算出权值
// 进行其他操作,例如显示weight值
Delay(0xFFFFF);
}
}
void ADC1_Init(void)
{
GPIO_InitTypeDef GPIO_InitStructure;
ADC_InitTypeDef ADC_InitStructure;
RCC_ADCCLKConfig(RCC_PCLK2_Div6);
/* Enable ADC1 clock */
RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1 | RCC_APB2Periph_GPIOA, ENABLE);
/* Configure PA1 (ADC1 Channel 1) as analog input */
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_1;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AIN;
GPIO_Init(GPIOA, &GPIO_InitStructure);
/* ADC1 configuration */
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);
/* ADC1 regular channel1 configuration */
ADC_RegularChannelConfig(ADC1, ADC_Channel_1, 1, ADC_SampleTime_55Cycles5);
/* Enable ADC1 */
ADC_Cmd(ADC1, ENABLE);
/* ADC1 reset calibration */
ADC_ResetCalibration(ADC1);
/* Check the end of ADC1 reset calibration register */
while(ADC_GetResetCalibrationStatus(ADC1));
/* ADC1 calibration */
ADC_StartCalibration(ADC1);
/* Check the end of ADC1 calibration */
while(ADC_GetCalibrationStatus(ADC1));
}
u16 ADC1_GetValue(void)
{
/* Start the conversion */
ADC_SoftwareStartConvCmd(ADC1, ENABLE);
/* Wait until conversion completion */
while (ADC_GetFlagStatus(ADC1, ADC_FLAG_EOC) == RESET);
/* Get the conversion value */
return ADC_GetConversionValue(ADC1);
}
void Delay(__IO uint32_t nCount)
{
for(; nCount != 0; nCount--);
}
```
