Can any one help me on the above post?

Thanks in Adavance

What happens if you replace all your code with this:

Byte[] bt = File.ReadAllBytes(@"\SD\Sample.bmp");

Which PWM dll do you have selected in your references?

This all started because I have this kit: http://www.seeedstud....html?cPath=138

And I wanted to get this sample working: http://www.seeedstud...k:_Tricolor_LED

I used a few pieces of code to compile this sample. Thanks goes out to everyone working on educating folks on how to work with all this.

I do NOT know electronics so please feel free to point out any issues you see.

NOTE change the last parm from true to false if you are using a cathode type RGB LED and connect
the cathode to the ground. I have not tested that as I only have an Anode LED.

led_r = new PWM(PWMChannels.PWM_PIN_D9, 100u, 0u, PWM.ScaleFactor.Microseconds, true);

Hi Greg,


Netduino Plus 2 works almost exactly the same as Netduino Plus 1...but the re-flashing method is brand new. SAM-BA is only used for Netduino Plus 1; you'll want to use STDFU and DFUSE for Netduino Plus 2.

Here are the full re-flashing instructions (and firmware) for Netduino Plus 2:

If you completely erase and then re-flash your board using those instructions, you should be back up and running. If not, we'll need to check the version of .NET MF SDK to make sure it's running QFE2.

Does this get you back up and running?

<TOTAL NOOB ALERT - read with caution>

I bricked my board at least 10 times Thursday using ?OLD? PWM code examples. The instructions linked above: http://forums.netdui...-firmware-v421/ saved me everytime.

Almost anytime I tried to run 4.1 PWM code it would lock the ND+ 2 and I would have to follow the steps above to get it working again. I am not sure if the issue is with the SecretLabs PWM port to 4.2 or what - but if I use the NETMF PWM libraries (Microsoft.SPOT.Hardware.PWM)it works.

Each time it locked I loaded the latest DFU I could find and was back up and running.

After a few hours (total noob) I was able to get a PWM project working that cycled my RBG LED. I am going to clean it up now and post it as a sample.

If you are having trouble with PWM please post which Class Library you are using - Microsoft.SPOT.Hardware.PWM or SecretLabs.NETMF.Hardware.PWM
