电机控制上位机问题优化

我在编写电机控制上位机时遇到比较棘手的问题,先介绍一下现状:
1.这是demo的winform:

目前已经实现电机的搜索、打开、根据模式启动等,但由于是需要精细化的输入控制的电流、速度或者位置,所以想在界面设计几个button或者textbox,可以在点击按钮或者在textbox中输入后回车就可以运行。

*我的问题出在:在发送代码下创建新的button并输入特定的数据,但在信息框中并没有输出;我的输入代码字节为一字节或者五字节,demo中为八字节,是否设置button时定义一或五字节输入也会有影响;应该如何改善呢?感谢!

2.如下是demo的发送代码

unsafe private void button_Send_Click(object sender, EventArgs e)
        {
            if(m_bOpen==0)__
                return;

            VCI_CAN_OBJ sendobj = new VCI_CAN_OBJ();
            //sendobj.Init();
            sendobj.RemoteFlag = (byte)comboBox_FrameFormat.SelectedIndex;
            sendobj.ExternFlag = (byte)comboBox_FrameType.SelectedIndex;
            sendobj.ID = System.Convert.ToUInt32("0x"+textBox_ID.Text,16);
            int len = (textBox_Data.Text.Length+1) / 3;
            sendobj.DataLen =System.Convert.ToByte(len);
            String strdata = textBox_Data.Text;
            int i=-1;
            if(i++<len-1)
                sendobj.Data[0]=System.Convert.ToByte("0x" +strdata.Substring(i * 3, 2),16);
            if (i++ < len - 1)
                sendobj.Data[1]=System.Convert.ToByte("0x" +strdata.Substring(i * 3, 2),16);
            if (i++ < len - 1)
                sendobj.Data[2]=System.Convert.ToByte("0x" +strdata.Substring(i * 3, 2),16);
            if (i++ < len - 1)
                sendobj.Data[3]=System.Convert.ToByte("0x" +strdata.Substring(i * 3, 2),16);
            if (i++ < len - 1)
                sendobj.Data[4]=System.Convert.ToByte("0x" +strdata.Substring(i * 3, 2),16);
            if (i++ < len - 1)
                sendobj.Data[5]=System.Convert.ToByte("0x" +strdata.Substring(i * 3, 2),16);
            if (i++ < len - 1)
                sendobj.Data[6]=System.Convert.ToByte("0x" +strdata.Substring(i * 3, 2),16);
            if (i++ < len - 1)
                sendobj.Data[7] = System.Convert.ToByte("0x" + strdata.Substring(i * 3, 2), 16);

            if(VCI_Transmit(m_devtype,m_devind,m_canind,ref sendobj,1)==0)
            {
                MessageBox.Show("发送失败", "错误",
                        MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
            }
        }

3.这是厂家的效果,也是我想达成的界面。

    首先,确认一下代码中是否有针对输入框内输入特定数据时的响应函数。其次,检查一下设置button时是否定义了输入的字节数,如果定义了的话,应该根据实际情况来设置。建议尝试修改响应函数,使其能够正确解析输入的数据并显示在信息框中。另外,如果还是不能解决问题,可以考虑使用调试工具进行排查,以找出问题所在。
