Hi Remo Thanks for answering after such a long time. In the mean time I seached more and more on the internet and found the solution (if you're still interested, otherwise this answer is usefull for others). It looked strange to me that in all the examples I found the buffer size was always initialized with 513 bytes i.s.o 512 (as the normal length of DMX is). But it seems that the first byte always have to be 0 and acts as a kind of start byte. So in order to send 255 to channel 1, you have to send:...

Hi Herman I've abandoned that project a longish while ago. Never could get it to work. Cheers Remo

Hi Remo It's a little bit later, but have you already got it working. I'm currently trying to get this working with .NET 7 and I'm facing the same problem (and using the samen parameters). Hope to hear from you Greetz, Herman

I'm wanting to create my own, special purpose DMX program, and Auto Hot Key is the only scripting language I've ever learned, but not learned very well. I'm trying to use the OpenDMXDLL, that comes with one of the example interface programs, and a plugins directory containing Enttec.dll and Enttec.pdb. I had some help making this script but I have no idea if we are even close to getting this correct. This script should open the OpenDMXDLL and the Enttec dll which both return a value of 0, meaning...

Hi ManMartin! Don't know if you're still around... I've got your opendmx.dll working, but the splash screen at start-up is a problem. I would love to get the source code, or find a way to remove that message. Also be good to compile for 64 bit windows. Can you help anyway?

Hi Toni, my code only works with the OPEN model, I'm afraid. I had a look at the Pro Device's API and it looks very much like the API of the Ethernet to DMX Devices. It seems to be a complete different thing. The OPEN model (as far as I remember) does not work standalone, it needs the PC and the DLL to generate the DMX signal. The Pro Device seems to work standalone (so you could once set the DMX values and then disconnect the PC). Hope this helps... Regards Kai Markus

Hi Kai Markus, Tried your code and it seems like work cause i'm getting responses if the controller is or isn't connected, but it seems that isn't receiving data/or writing data to the device. (Led not flashes and DMX device isn't receiving nothing). This code works with the Enttec DMX USB Pro device? or is only for the OPEN model?

Please pay attention to my post "is there a memory leak..." and modify the write() method appropriate: https://sourceforge.net/p/opendmxusb/discussion/435109/thread/8d38ea34e7/

Hi, everyone! This works pretty fine... If you don't need logging, just omit the Log lines All You have to Do is to invoke DMX.start() at the beginning of your application. To modify DMX values, call DMX.setValue(channel,value) To stop DMX transfer (and at shutdown of application), set DMX.done to TRUE and invoke DMX.stop(). If you don't set DMX.done to true, the DMX send thread will remain running forever and your application won't shutdown properly. Feel free to ask questions Regards Kai Imports...

Hello from Germany! Just bought an USB interface and started programming it using C# and / or vb.net. I noticed that my application has got a memory leak which allocates about 512 Bytes of memory every 30ms. Had a deeper look into the example code snippets on the Open DMX homepage and was wondering if the memory leak could be located in the "write" method, the wrapper function: Public Shared Function write(ByVal handle As UInteger, ByVal data As Byte(), ByVal length As Integer) As Integer Dim Ptr...

Hey all, so I've searched pretty thoroughly—including on this forum, and it seems like all of the schematics and board designs for the OpenDMX box have been removed from the Entecc site, and I can't manage to find them anywhere else. Given that it purports to be an open hardware design, I would hope that that information would be public. Can anyone point me to where I could find the designs for OpenDMX? Hopefully they've just been moved elsewhere and not removed entirely?

I am having the same problem in passing the array. I know that VB has a strange way to pass the pointer, but am confused by the process. Did you ever find your answer?

Hi all From various sources, I've cobbled the following code together (using the FTD2XX_NET dll): Dim DMX = New FTD2XX_NET.FTDI() Dim IFD As Long = 30 ' Inter-Frame-Delay, default 30 ms between each frame Dim Buffer(512) As Byte ' the buffer to send Dim lngBytesWritten As UInteger ' how much has been sent Dim ftdiDeviceCount As UInt32 = 0 Dim ftdiDeviceList(1) As FTDI.FT_DEVICE_INFO_NODE Dim i As Long If DMX.GetNumberOfDevices(ftdiDeviceCount) <> FTDI.FT_STATUS.FT_OK Then Console.WriteLine("Failed...
