ALL项目之五：上位机数据读取程序

本代码是本人原创，如需转载请务必获得本人同意，否则保留一切权利！
在用VS2013写程序时遇到了‘’未找到约束ContractName‘’的问题，解决办法如下：

控制面板>程序>程序和功能 找到Entity Framwork Tools for vs2013软件右击修复 即可，注意要关闭VS2013。

下面的代码只列出了最核心的数据解析方法，数据帧为0XAA+0XAA+data

private void serialPort1_DataReceived(object sender, SerialDataReceivedEventArgs e)
        {
            byte[] receiveData = new byte[serialPort1.BytesToRead];    
            serialPort1.Read(receiveData, 0, receiveData.Length);
           s += System.Text.Encoding.Default.GetString(receiveData);
            //循环检测数据
            for (int i = 0; i < receiveData.Length; i++)
            {
                //如果标志位为真，存数据，注意此时数据总量不能超过最大量
                if (flagBit)
                {
                    notCalculatePressData[count] = receiveData[i];

                    if (count == PressCount * 4 - 1 + 4)//包括压力数据和加速度计数据
                    {
                        //发布数据满消息
                        DataFull(this, new EventArgs());
                        count = 0;
                        flagBit = false;
                    }
                    else
                    {
                        count++;
                    }
                }
                //如果标志位为假，检测数据头
                else
                {
                    if (receiveData[i] == 0xAA && receiveData[i + 1] == 0xAA)
                    {
                        flagBit = true;
                        //跳过第二个数
                        i = i + 1;
                        count = 0;
                    }
                }
            }
        }

public void DataCalculate(object sender, EventArgs e)
        {
            int k = 0;
            for (int i = 0; i < notCalculatePressData.Length - 5; i = i + 4)
            {
                pressData[k] = ((int)notCalculatePressData[i] << 24) + ((int)notCalculatePressData[i + 1] << 16) + ((int)notCalculatePressData[i + 2] << 8) + (int)notCalculatePressData[i + 3];
                k++;
            }
        }
