#6084 What is the Netduino Mini?

#6120 What is the Netduino Mini?
Posted by teachop on 15 December 2010 - 12:59 PM in Netduino Mini
Not that I know of in the price range of the MC33269. The LT1965 is great, but too expensive! LP3871 instead of U5 would work in both applications, might be < $1, and is very LDO. Merry Christmas to you and yours too.Any particular power regulators you'd like us to investigate?

Are you up-to-date on your firmware?
MFDeploy SolutionReleaseInfo.SolutionVersion = 4.1.0.5 which I think is up to date. The program is tiny, a variation on the example LED blinker.

#6918 Any Netduino Plus Stock

#6940 Any Netduino Plus Stock

Thank you - will keep checking. For some, Netduino allows experience in C#, .NET, Visual Studio, to be put to work in embedded apps. But I am the other way around, and with this learning C#, .NET, VS, building off familiar embedded territory. Good stuff.you should see them in stock at some local resellers this week and next.

Nice. I don't see any listings for Netduino Plus on Amazon, only Netduino and Netduino Mini. Can you post a direct link?Got one of those from Amazon. They have one left in stock

I see them in stock now. Put an order on Amazon for one...Got one of those from Amazon. They have one left in stock
#7304 Problem with Analog Input
Posted by teachop on 09 January 2011 - 02:25 AM in Netduino Plus 2 (and Netduino Plus 1)
Where is the Rev. B schematic for Netduino Plus found, from the download page I get Rev.A. I can see a circuit for switching aref on the Netduino schematic, but not on the Netduino Plus one.the schematics is for the latest Rev. B board

#7719 Netduino Plus Firmware v4.1.1 ALPHA 5
Posted by teachop on 15 January 2011 - 11:07 AM in Netduino Plus 2 (and Netduino Plus 1)
Yes pretty much. I also spent more time with the .5 version, and it isn't very reliable either, sometimes requiring usb cable pulling. Jacking the cable sometimes causes VS to terminate however. Here is a summary of the entire Plus experience (XP in VirtualBox on Ubuntu):do you have the same experience while using the beta 1 release?
Initially installing the driver (first connect of Netduino to USB), the driver installed, but after the progress bar fully filled, it never concluded the driver wizard, and required a boot. The driver did install however, and the device enumerates every time.
Using MFDeploy to install software, often the Ping hangs, requiring usb jacking. Same things happens when checking version. Fool around enough and it works. This cable jacking sometimes causes MFDeploy to terminate, sometimes not. After Browse... and select, the Deploy often hangs. Same thing. I think the pattern that works is to connect the device after hitting deploy. Anyway it eventually works, but after it proceeds to executing Application it gets stuck until the device is unplugged.
In Visual Studio, debugging has never worked once, fooling with the cable here then terminates VS. Starting without debugging can normally be made to work, wait for it to finish building and get stuck, then jack the cable, and deploy completes (sometimes VS terminates).
Thats about it. None of them are reliable enough to allow a development work flow to proceed. The Netduino Mini seems to work a bit better, VS terminates sometimes, but most of the time it works (using the RS-232 port with a Prolific USB serial cable).

I put Vista back on an old PC and thing work, I will use that. If you need alpha/beta testing on Ubuntu/VirtualBox let me know, everything is still installed on my main machine (Linux).None of them are reliable enough

#8111 Component locations
Posted by teachop on 22 January 2011 - 06:32 PM in Netduino Plus 2 (and Netduino Plus 1)
I generally find my reasons!You shouldn't ever need to probe individual components
The resistor designators would help the most when poking about...If ther are no easily readable numbers on the part, it's probably either the MUX in the corner, or an SMT cap/resistor/transistor.

#8198 FreeRTOS
Posted by teachop on 23 January 2011 - 07:14 PM in Netduino Plus 2 (and Netduino Plus 1)
You asked, no laughing. Two current projects might fit: One is a midi solenoid-over-wind pipe organ (currently arduino), second is a physical email/gmail/snail notifier wall hanging. The second is what I bought the board for...Are you thinking of building anything else with FreeRTOS?
The demo I built is uip. A few edits of the web server got it running, have not touched the stack.is FreeRTOS using lwIP or uIP?
#8282 FreeRTOS
Posted by teachop on 24 January 2011 - 10:51 AM in Netduino Plus 2 (and Netduino Plus 1)
Yes, CodeSourcery lite. Used eclipse for the environment, but no debugging. Figured out a pattern so that SAM-BA works every time, at first it was a pain. I had to make some changes in the web server because it was crashing, other than that it was just stuff like LED defines, and it worked.What compiler are you using teacop? Codesourcery? Which version?
#8283 FreeRTOS
Posted by teachop on 24 January 2011 - 10:57 AM in Netduino Plus 2 (and Netduino Plus 1)
It is stable enough, in the short time I have had it running, once it is going, it doesn't hang up. There are dropped IP packets but I don't know if that is a problem or not yet. The flakes are in the connect/disconnect ethernet. I have to 1) power the Netduino Plus, 2) connect the ethernet. If the ethernet is connected already, then it sometimes isn't working, so I need to investigate that.The demo you built on uIP...is the networking solid now or still flaky? We've been looking at ways to get uIP up and running on the Netduino Plus.

#8385 FreeRTOS
Posted by teachop on 25 January 2011 - 09:16 AM in Netduino Plus 2 (and Netduino Plus 1)
Nice. Was very interested in your compiler experiences. I used CodeSourcery lite GCC, and have not tried the others. In the demo I built, there is a look-up function in the cgi code that crashes, and I had to rewrite it. I suspect that is a compiler issue as well. Other than that it was just, like you experienced, configuration details.I got Netduino plus running with FreeRTOS 6.1.0+lwip 1.1.0, compiled with GCC-4.1 toolchain from www.gnuarm.com
with few changes.
I also tested with YAGARTO version 20100703, same code, not working. cpu hangs once network cable plugged.
All in all, FreeRTOS+CodeSourcery+eclipse on Netduino Plus is looking pretty good, and I suppose I can live with SAM-BA! It seems my first Netduino Plus project will be without a .net. This will give performance and easy access to the irqs. You can't beat the hardware feature set for the price (wish there was a JTAG though).
I have not tried to get the SD card going with FAT file system yet on FreeRTOS, have you worked on that at all?
#8629 FreeRTOS
Posted by teachop on 28 January 2011 - 07:07 PM in Netduino Plus 2 (and Netduino Plus 1)
Makes sense to me, I agree use a generic name for non .NET applications, and have the FreeRTOS and NUT/OS as sub-categories, I am sure more will follow. Can you move existing FreeRTOS and NUT/OS threads under them to seed the process?Quick aside...should we make a "FreeRTOS and C/C++ programming" forum?
