自上周以来,我遇到了一个问题,尽管有高级开发人员的建议. 我想通过COM端口通过计时器向电机发送电动命令. 当我一步一步地或当我添加一个停止点时,这是 好的！但是,当我让计时器和
我想通过COM端口通过计时器向电机发送电动命令.
>当我一步一步地或当我添加一个停止点时,这是
好的！但是,当我让计时器和程序运行时
他们自己,机动化命令永远不会发生！为什么？命令
应该按照一步一步的方法运行！
我实际上是在没有任何参数的情况下调用方法envoi_commande_motorisation().它只是将特定格式的帧发送到COM端口,以使电机移动.然而,在逐步退出调试时似乎永远不会被调用.这个命令包含在Timer_moto_tick(发送者,e)中作为Timer_moto.tick,它只是我定期验证电机是否在右边方位的定时器,知道它在Demande_etat_motorisation()中的位置.
我将计时器的频率从1000毫秒改为3000毫秒,每次500毫秒,但它没有改变任何东西……
>我添加了一个调用envoi_commande_motorisation()的按钮
手动,它的工作原理！然而,这是手工制作,我想自动化
它.
这是犯罪现场的图片：
Private Sub Timer_moto_Tick(sender As Object, e As EventArgs) Handles Timer_moto.Tick
'asking for the motor position
Demande_etat_motorisation()
'checking if we are acually in the automatize management of the motor and not in the manual way
If RadioButton_Manuel.Checked = False Then
'checking if the motor isn't already at the right place
If ((CDbl(Liste_azimut.Text) <> Val(Aff_position_azimut_source.Text)) Or (CDbl(Liste_elevation.Text) <> Val(Aff_position_site_source.Text))) Then
'otherwise we change the motor position text and say him to go this way

到目前为止,高级开发人员仍然认为这是一个定时频率问题.
也许我应该处理串口的中断,但我怎么能这样做呢？他告诉我为每个端口设置阈值,以便通过中断开始读取,这样我就可以在缓冲区满时读取它.
编辑：
Diagnostics.Debug.Writeline
据我所知,我在我的程序可能崩溃的地方写了Diagnostics.Debug.Writeline(“这里有一些特定的文字”).实际上,在拿起终端上写的行后,我注意到它是Serialports.Writeline(,,)会产生问题.
确实有以下代码和调试行：

'asking for the motor position
Demande_etat_motorisation()
'checking if we are acually in the automatize management of the motor and not in the manual way
If RadioButton_Manuel.Checked = False Then
Diagnostics.Debug.WriteLine("test if we are at the right place")
If ((CDbl(Liste_azimut.Text) <> Val(Aff_position_azimut_source.Text)) Or (CDbl(Liste_elevation.Text) <> Val(Aff_position_site_source.Text))) Then
lecture_port_comm_moto()

Liste_elevation.Text = CType(Val(Aff_position_site_source.Text), String)

每个Diagnostics.Debug.WriteLine消息都会在终端上读取并显示,但相机不会移动.因此,当链接到COM端口4时,我认为是严重问题的Port_serie_4.Write(tableau_hexa,0,13),
即使其余代码延迟如下所示.
奇怪的是,如果我们在正确的地方,它总是写我测试.即使我给它命令移动,就好像他认为我们在正确的位置,除非点击要求envoi_commande_motorisation()的按钮.
.
延迟
我在这里也加了一个延迟：
Case Zone_param_comm4.Text
Diagnostics.Debug.WriteLine("we are going to write in COM port 4")
Port_serie_4.Write(tableau_hexa, 0, 13)
System.Threading.Thread.Sleep(500)
Diagnostics.Debug.WriteLine("We just wrote in COM Port 4")
然而,目前没有任何改变.
也许我应该删除这个问题代码的某些部分或从上面删除.随意提出建议并感谢您为解决此问题所带来的所有帮助.
我想你曾经试图在这里做太多.也许你需要从编写一个真正有效的非常简单的程序开始,然后构建它.首先,使用表单和按钮创建一个新项目.单击该按钮时,将打开COM端口.
如果可行,您只需在打开端口后发送一个命令.将相机设置在给定位置的命令.
如果可行,则添加一个TextBox,您可以在其中输入所需位置.因此,当您单击按钮时,它会将相机移动到该位置.
如果有效,……
而且你一直在这样建立,直到你发现出了什么问题
