This firmware has been superceded by Netduino Plus Firmware v4.1.1 beta 1

Chris, Upgraded from alpha6 to alpha7 and all ok, booting code does not hang in vs deployment so no need for build3 any longer. Alan

Cool. Thanks for testing this, Alan.

.EnableDhcp()

kind of work, I have to restart NetduinoPlus to get a IP from my router, then it works fine every time I start the board. If I just run the code I still get 0.0.0.0

Thanks, Ken. So we're getting closer, but are not quite there. Let's see if we can get this problem fully solved over the next few weeks before 4.1.1 goes gold.

Confirmed. My fingers can take a break from pulling out and plugging in the USB cable

I upgraded my N+ and lost USB connection. My PC doesn't recognize Netduino.

Hi,

Installed the latest version of the firmware on my Netduino Plus so I could use the updates to the i2c interface. I'm trying to interface to an MD22 motor controller from My link. When I run my test project I get the an exception, please see attached screen shot. The exception occurs when I call the i2c execute method. I have also attached by VS2010 project to help.

Any idea what I'm doing wrong?

Hi ScubaBoy,

Do you have a diagram of how the MD22 motor controller is attached to your Netduino? Does it have integrated pull-up resistors? And if not, have you added them to your I2C data and clock lines?

Hi madartsoft,

Were you using serial deployment or USB deployment before you upgraded your Netduino Plus?

If you hold down the pushbutton on your Netduino Plus while plugging it into your computer, can you immediately PING it from MFDeploy?

[Worst case scenario, you can always erase your Netduino Plus completely and reflash it...but really, firmware upgrades should go off without a hitch.]

Chris

I have got pull up resistors attached to the data and clock lines (MD22 doesn't have integrated ones), the MD22 motor controller is connected to analogue pins 4&5 for i2c side of things and gets +5v and 0v from the Netduino.

In all likelihood, there is a problem with the device address - the current I²C implementation supports only 7-bit addressing, so 0xB0 is out of range.

I use USB deployment as serial was never worked for me. I had to restart my PC then it seems that everything is ok.

Thanks for pointing that out, a little shift to the right and it's working

[Corey Kosak]

Is the source code of the latest alpha firmware available somewhere?

I can send you the diff files if you'd like, Corey. With v4.1.2, we'll also check in the betas online--but for now we just post the final versions. CodePlex should make it much less time consuming to package source updates and we can make it part of the workflow...

Sure, that would be great! The only place I know to get source is here, and I assume that's rather out of date by now, and I don't know where else to go. Thanks!

Chris, Will CW2's OneWire function be in the firmware? /Ken

[Chris Walker]

Will CW2's OneWire function be in the firmware?

The current plan is to integrate CW2's OneWire into v4.1.2 using runtime native code interop.

That sounds great, when do you think 4.1.2 is released (any betas before with OneWire?)
