Android Question Convert java to b4a

[george21]

Hello,

Could someone Please help me convert this java code to b4a or how could I use it with inline java.
Thank you

private void Init(int address) throws Exception
{

serialPort.setBreakOff();
Thread.sleep(300);

serialPort.setBreakOn();
Thread.sleep(200);

// Bang the bits (one byte) of our address
for (int i = 0; i < 8; i++)
{
if (((0x01 << i) & address) > 0)
{
serialPort.setBreakOff();
}
else
{
serialPort.setBreakOn();
}

Thread.sleep(200);
}

serialPort.setBreakOff();
}

What is serialPort?

Why is this code holding the main thread? Doesn't look good.

I believe serialPort is actually JD2XX ( for reading/writing to UARTS )

I am trying to bitbang the port at 5 Baud, this is as far as i got to try convert the java code to b4a.


Private Sub Init(ByVal address As Int)

mSerial.setBitmode(True,0x00,0x00)
Sleep(300)

' Start bit, 200ms low
mSerial.setBitmode(True,0x01,0x01)
Sleep(200)

' Bang the bits (one byte) of our address
For i As Int = 0 To 7
If ((0x01 << i) And address) > 0 Then
mSerial.setBitmode(True,0x00,0x00)
Else
mSerial.setBitmode(True,0x01,0x01)
End If

Sleep(200)
Next i

mSerial.setBitmode(True,0x00,0x00)
End Sub

It doesn't look like Android code.

 

[Daestrum]

    For i = 0 To 7
        If Bit.And(Bit.ShiftLeft(1,i),address)>0 Then
            '???
        End If
    Next

Thank you Daestrum.

It's going to sound more like Morse code. ?

Also, might be a good idea to check that calls to Sleep() are reliably accurate enough for timing bits.
