Hi Zoot -

First, thanks for taking the time to carefully read and understand my question. I appreciate it. I just have couple points I need to clarify:

When you refer to a USB to serial adapter, are you referring to a cable? (USB to 24-pin serial physical adapter?) Can't I just do this with my USB cable? (If not, I will probably scratch this feature.)
 

When the Netduino is connected by USB, I DO see the Netduino device under USB devices. But I am unable to configure any COM port for it. (I believe other USB evaluation boards allow you to config a COM port in Dev Mgr under the USB device, but I may be wrong.)

Also, I have worked with other eval board (TI MSP430 and Stellaris) on this both of my machines and the used Putty via COM port (#?) to connect Putty to their UART (serial text buffer). All via USB cables. Now I cannot find those COM ports ... this puzzles me but is, perhaps, a distraction.

THANKS a ton!

Chris -

I have the exact same problem: My Go! appears to be dead. (Perhaps also my ShieldBase, no way to tell.)

When I plug in my Go! none of the port lights illuminate, only the main white LED by the micro USB port.

It is not recognized by MFDeploy nor the STDFU tools.

Yes, I've tried putting it in bootloader mode by holding down the button while plugging it in.

The last thing I was doing was I had the LadyAda Motor Shield attached to the ShieldBase. I was attempting to use a MotorShield.cs port that I had gotten from this forum. I had made some changes to make it compatible with my Netduino Go!

First attempt to deploy my project failed and that's when I realized it's dead.

I bought my Netduino Go! around last Christmas. Can't remember where I bought it from.

Please tell me I don't have to buy a new one.

Should we not be using the LadyAda Motor Shield with our ShieldBase? It has a PWR jumper near its external power block ... I had the jumper OFF so as not to damage the Netduino components.

Thank you!

Hi Olaf. Thanks for your comments. 

The motor I was attempting to use is a tiny water pump ... something that might be used for a desktop water feature. It fits in the palm of my hand ... I could close my hand around it and you wouldn't see it. But it DOES draw over 0.5A. 

I will figure out the exact draw later tonight when I replace the 10A fuse in my multimeter.

In the mean time, the vendor saw that I bought 2 of these things from him many months ago and is shipping me a better board right away. I thought that was really good of him.

I would find it especially valuable if someone could tell me that I did something wrong PRIOR to letting the smoke out of 1/2 of my motor driver. (I also have another identical 1 that is still intact. So I still have 1.5 of these boards.)

If someone could tell me something like, "Well, you need to connect IB to ..." or some other solution.

Thanks for your help.

Thanks, Mike. Yeah, that's the info I needed.

So, I'm not going to be able to create any kind of radio signal by toggling a port on the Netduino ... at least not in the amateur bands (2 meter band). That would require about 145 MHz.

I would have to create some dedicated tank circuit and then perhaps manipulate it using the Netduino.

Sure. Of course it's unanswerable if there are other processes taking up cycles. Thanks.

I'd like to get a ballpark idea of the maximum frequency I can toggle the port with NOTHING else going on. A theoretical limit if nothing else.
