首先，需要了解MPX4115是一种压力传感器，其输出为模拟电压信号，需要通过ADC模块转换为数字量才能进行处理。因此，需要将MPX4115的输出接到ADC模块的输入端，然后通过调用ADC_Read函数来读取ADC模块转换后的数字量。

假设MPX4115的输出接到了ADC0832模块的第1路输入端，那么需要将ADC_Read函数中的channel参数改为1，即将switch语句中的case 1:下的代码保留，其余的删除。

另外，由于ADC0832模块的输出为8位数字量，而MPX4115的输出为10位数字量，需要修改ADC_Read函数中的两个for循环来适配MPX4115的输出精度。具体修改如下：

unsigned int ADC_Read(unsigned char channel)
{     
    unsigned int result = 0;     
    unsigned char i; 	
    switch(channel) 		// 选择ADC0832     
    {         
        case 1:             
            ADC0832_CS1 = 0;             
            ADC0832_CS2 = 1;             
            ADC0832_CS3 = 1;             
            ADC0832_CS4 = 1;             
            break;         
        default:             
            return 0;     
    }          
    
    // 开始转换    
    ADC0832_CLK = 0; 	
    ADC0832_DO = 1; 	
    ADC0832_CLK = 1; 	
    _nop_(); 	
    _nop_(); 	
    ADC0832_CLK = 0; 	
    _nop_(); 	
    _nop_(); 	
    ADC0832_DO = 0; 	
    ADC0832_CLK = 1; 	
    _nop_(); 	
    _nop_(); 	
    ADC0832_CLK = 0; 	
    _nop_(); 	
    _nop_(); 	
    ADC0832_DO = 1; 	
    ADC0832_CLK = 1; 	
    _nop_(); 	
    _nop_(); 	
    ADC0832_CLK = 0; 	
    _nop_(); 	
    _nop_(); 	
    ADC0832_DO = 0; 	
    ADC0832_CLK = 1; 	
    _nop_(); 	
    _nop_(); 	
    ADC0832_CLK = 0; 	
    _nop_(); 	
    _nop_(); 	
	
    // 读取转换结果
    for(i = 0; i < 10; i++) 	
    { 		
        result <<= 1;         
        ADC0832_CLK = 1; 		
        _nop_(); 		
        _nop_(); 		
        if(ADC0832_DO)             
            result |= 0x0001;         
        ADC0832_CLK = 0; 	
    }     
    
    return result; 
}

注意，这里假设ADC模块的输入范围为0~5V，如果MPX4115的输出范围不在此范围内，还需要进行电平转换或者放大缩小等处理。
