B4R Question OV7670 camera

[derez]

I got one and started googling to find how to interface it to Arduino. Very disappointing.
The closest to make some sense for me is this https://github.com/ComputerNerd/ov7670-no-ram-arduino-uno
Does anybody have any experience with this camera ?

I have advanced a big step and now I can see the serial data from the camera in the monitor.
Any idea how to read it in the PC and convert it to an image (I thing it is BMP) ?
I'll try with this https://www.b4x.com/android/forum/threads/b4x-bytes-to-file.70111/#post-445167

Trying the following code but I don't get an image:

Sub AStream_NewData (Buffer() As Byte)
    bc.ArrayCopy(Buffer,0,full,offset, Buffer.Length)
    offset = offset + Buffer.length
    Log(offset)
End Sub

Sub show_Action
    Dim temp(offset) As Byte
    bc.ArrayCopy(full,0,temp,0,offset)
    iv.SetImage ( BytesToImage(temp))
End Sub

Public Sub BytesToImage(bytes() As Byte) As Image
   Dim In As InputStream
   In.InitializeFromBytesArray(bytes, 0, bytes.Length)
   Dim bmp As Image
   bmp.Initialize2(In)
   Return bmp
End Sub

If the code should work then the reason must be the camera's stream...

Hi Derez,

Now I'm using OV7670 camera to write on my project. Do you have any solutions to write this hardware.

Thank you
