Pressing F5...Ok While I powered off and powered on usb........not working.

Found bug again, Chris

While I powered off and powered on usb........NOT WORKING     

Pressing F5...Ok

I converted from Arduino To NGO.

Here is link:http://arduino.cc/en...orial/ShftOut22

schematic:http://arduino.cc/en/Tutorial/ShiftOut Look for 16 leds

Here is my source code:

Sorry chris.

Hi supra, That's great additional info; thank you. With the 4.2.2 firmware, Netduino Go's USB name has changed to "Netduino" (instead of "NetduinoGo"). This is to enable new and future capabilities. To update the deployment target for your device. 1. In Visual Studio, open up "Project Properties > .NET Micro Framework". 2. Change the transport from USB to Serial. 3. Change the transport from Serial to USB. 4. If it is not already selected, select "NetduinoGo_Netduino" as the target device. 5. Save your project. That should get you back up and running; let me know how it goes! Chris

Thank, Chris. I got USB device working. All I see is Netduino instead of NetduinoGO, as I understand.        

But what happen! When I power off usb and power on usb again. The clocks such as data, latch and clock are  not working. But same as above #4.

Can you give me any hints as posting #4?

Supra

When I power on usb. The led is stay on but the LEDs not moving. Is something wrong with SPI?

do you have a logic analyzer that you can hook up to the pins to analyze the SPI data pattern which you're outputting from the shield base pins? Chris

No.

I Added 3 leds for each clocks. By monitoring each clocks and see if the clocks is working or not.

Hi Chirs,

But why NGO is not working when I power off and power on USB again?
