Gotcha, Thanks for the replies

Hi GlenEE,

What type of project did you create? Netduino Plus 2 Application? Netduino Plus Application?

Check to see if your project references contain the SecretLabs.NETMF.Hardware.Netduino.dll assembly...or the SecretLabs.NETMF.Hardware.NetduinoPlus.dll. The "NetduinoPlus" one is for the original Netduino Plus, and should be replaced if you're upgrading a project. Otherwise the pins won't match up.

BTW, you can now change the intensity of the blue LED. If you create a PWM, you'll notice that the PWMChannels enumeration has an option for PWM_ONBOARD_LED Just be sure to do a PWM.Start() after creating the PWM instance.

I had a Netduino project initially, today i tried it with the Netduino Plus 2 application, and im still not getting anything on the display. Also my project contains the SecretLabs.NETMF.Hardware.Netduino.dll assembly.

SN. I really appreciate the prompt responses and assistance.

Hi GlenEE,

Okay, I just ordered that LCD shield. We should receive it on Tuesday or Wednesday of next week.

In the meantime, what line of code is causing the error?

Is there any chance you could share your project (which works on Netduino Plus gen1) so that we can repro all scenarios here?

We should be able to get this up and running pretty quickly,

Thanks GlenEE!

Im using the sample code stefan developed.

I also couldn't get the Blinky example code to work. It worked on the Netduino Plus gen1. The code deployed to the board and didn't show any errors, but the LED doesn't blink. I also noticed that when the board is plugged into a network connection, the network LEDs don't come on either. The board is sending emails though, the LEDs just aren't working.

Here is the link to the adafruit LCD shield im using. when i walked through my code as soon as i send a command to clear the LCD display the code errors. the lcd shield im using is available at the following link. (http://adafruit.com/products/716)
