HI, can anyone help me for my little experiment?
i have 2 I2C LCD and i want sent text to these lcd from VB6.0

this is the form in vb6 that i create

and this is what i do in vb..so i need help to fill code to cmdSENT1 and cmdSENT2

Private Sub Form_Load()
On Error Resume Next
With MSComm1
If .PortOpen Then .PortOpen = False
.CommPort = 3
.Settings = "9600,n,8,1"
.DTREnable = True
.RTSEnable = True
.RThreshold = 1
.SThreshold = 0
.PortOpen = True

End With

If MSComm1.PortOpen = False Then
MsgBox "No USB device available or wrong Com Port number", vbCritical, "Please check!"
End If

End Sub

Private Sub cmdSENT1_Click()

End Sub

Private Sub cmdSENT2_Click()

End Sub

this is what i do in arduino..also need help for this sketch.

#include <Wire.h>
#include <LiquidCrystal_I2C.h>

LiquidCrystal_I2C lcd1(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE); // Set the LCD I2C address
LiquidCrystal_I2C lcd2(0x3F, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE); // Set the LCD I2C address

void setup()
{
lcd1.begin(16,2);
lcd2.begin(20,4);

lcd1.backlight();
lcd2.backlight();

Serial.begin(9600);

lcd1.print("LCD 1 Ready");
lcd2.print("LCD 2 Ready");
}

void loop()
{
if (Serial.available()){
delay(100);
lcd1.clear();
lcd2.clear();
while (Serial.available()>0){
lcd1.write(Serial.read());
}
}
}

sorry for my bad english..

  lcd1.begin(20,4);
  lcd2.begin(16,2);

Are you deliberately trying to confuse yourself ?

Your VB screenshot shows LCD1 has 2 rows of text and LCD2 has 4. I know that this is trivial to put right but do it now and don't wait to fix it later. More consistent names for the text boxes would also be a good idea.

UKHeliBob:

  lcd1.begin(20,4);

lcd2.begin(16,2);
