Bonjour,
peux-tu donner le programme en VS C++ ?
oui bien-sur le voilà :
Imports System
Imports System.IO.Ports
Public Class Form1
Dim comPORT As String

comPort_ComboBox.Items.Add(sp)
Next
End Sub

If (comPort_ComboBox.SelectedItem <> "") Then
comPORT = comPort_ComboBox.SelectedItem
End If
End Sub
Private Sub connect_BTN_Click(sender As Object, e As EventArgs) Handles connect_BTN.Click

SerialPort1.Close()
SerialPort1.PortName = comPORT

End Sub

End Function

J-M-L:
Je vois que vous avez viré l'idée du marqueur de fin
puisque la seconde ligne est en commentairec'est très lent sans doute parce que
Serial.parseIntattend le début du message suivant (qui commence par une lettre) avant de continuer ou un timeOut de l'ordre de la seconde par défaut...c'est pour cela qu'il vaut mieux virer cette commande et gérer la communication "à la main" vous même
J'ai fais une erreur ce n'était pas souhaité ou un oublie, mais du coup je le retire ?
