Unfortunately, as it's a joint endeavor (Atmel+Microsoft+Secret Labs) I don't know 100% for sure. We're _really_ close...but it's that last 1-10% that seems to take forever.

Hi all
Thangs for a great toy. Only missing one thing. Comms trougth the usb port.
Is there any news about this?

Hi Dennis,

We just barely enabled the first part of this about a week ago. You'll still need to deploy/debug through serial, but you can now send bidirectional data through the USB port. Best of all, instead of CDC it's using HID comm...so it's driverless and you can autodetect the Netduino (so no making users select a COM port).

Check it out in the Netduino Beta forum. Requires v4.1.2 alpha firmware.

Chris, When this is fully implemented will we be able to deploy/debug over USB as well as CDC comm? -Jason

Hi foxxjnm,

It's theoretically possible, but we're still working out the usability issues. We'll know more as the feature nears gets further through the beta cycle.

Thanks for the quick reply. I will keep my fingers crossed!

Hi Chris, any news to report on USB yet?? :)

Hi Jim,

Hi Chris, any news to report on USB yet?? :)

You can deploy over serial (RS232/TTL) today and use USB for communication. Required v4.1.1 firmware or later.
http://forums.netdui...tion-using-usb/

We're looking at ways to support simultaneous USB comm and debug... Nothing final on that today.

I thought, too, the Netduino would be able to do RS232-communications the same way the Arduino does - the FTDI-breakout is almost 50% of the price a netduino is in Germany, so this is a hard blow against my budget and it adds to the mess on my breadboard :( Although it's too late for me now, I'd appreciate this feature very much!! Regards Mark.

I am very excited about the prospects with these new features. Chris, for what it's worth, the USB comm and debug would be fantastic. Hope you guys manage to get it going with all the partners involved. Well done!

+1 on this feature.. It would be nice to be able to see on the computer data from the netduino without having to plug another USB/serial connection. is there an ETA for this? Thanks Luis

Hi Chris, are you any closer to a beta on this feature? Thanks!

I built this little board to add Serial to USB communications to the Netduino: https://www.loveelec...--barebone-ftdi Its use is explained in this netduino tutorial: https://www.loveelec...how-to-use-them It shows how to use the Serial device to output to a WCF application.

Thanks, and your tutorial is a great resource for using a USB-Serial adapter with the Netduino. However, a user who buys a Netduino wants to get started with hardware and try it out with a low cost of entry. If I buy a Netduino for $30 I don't want to pay $25 just to talk to it, not that you shouldn't make money on your invention!

Hey guys, Just received my netduino today, was expecting this feature from the get go as well. Was hoping to be able to communicate between my application, I still can through an FTDI, but I really don't want to spend more than I already have. This would also mean another week or so of waiting. Oh well, that's no problem. At least I can connect the 5v -> 5v and not have to worry about two usb cables on a released product. Being able to program in Visual Studio is well worth the wait. Imagine that, two usb cables to do the job of one, haha. How has development been going Chris? Does the 4.2 beta firmware add anything to this issue? :) Really looking forward to getting started on my project, as well as this feature. Edit: Would an external usb library work such as: http://sourceforge.n...s/libusbdotnet/ Thanks, - Oammar

We're part way there. It should technically be possible to enable simultaneous debug-and-deploy, as long as your device is powered via external DC power and the configuration is updated before USB is connected to your PC. We're working out a simpler method...more on that when I have an update for you. Chris

Can you use the above mentioned technique now??? Do I need the latest firmware to do this? So you're saying I would deploy to the device, unplug it, put it on DC power, and then plug it back in?

Thanks!

In theory, if you plug the device into DC power and reconfigure the USB configuration so that it exposes two interfaces (USB HID/CDC and NETMF debug) as two different devices...then you should be able to do bi-directional communication while debugging.

You'd need to plug in your Netduino's USB cable after the reconfiguration took effect.

You could also change the USB configuration in the Netduino firmware source to include both channels by default--or upload a new "XML" USB configuration using MFDeploy.

There are a lot of options. We're trying to sort out the "best option" right now, for an "officially supported" solution.

It's been a while, any word on this?

Just curious about this, Any reason the Netduino couldn't show up as a composite device...like maybe the device it is already showing up as AND a USB serial device? Seems like that would only require a firmware change??

Just curious.

I second this question, has there been any progress yet?

Thanks,
