Hi to all of you very clever people, I Am torn between the netduino and the mbed! The netduino has an environment that I am familiar with, and a hardware format that I can take advantage of, however moving from prototype to in project I would love the format of the Mbed (all of the pins exposed to the user, incising the Ethernet in a breadboard format) As the Mbed is an arm 32bit microcontroler, has anyone thought about porting the firmware to the Mbed? (it is using a NXP LPC1768 arm processor) Adam Clifford

The mbed is interesting enough. 100 Mhz. But what do you want to use all those clock cycles for? FFT? (They run fine on Netduino as well btw.) And the mbed is only a header board, so you have to buy another board (or a bunch of connectors) to use it. Clumsy. If you should compare it to anything it should be the Netduino Mini. Btw, the netmf is not easily ported to the mbed as it only got 64k ram.

I was just thinking about the header board style being easier to implant into a permanent project in replacement of the netduino plus, as I need ethernet, and want to take advantage of the on silicon port. It would be cool if the mini had a breakout for the ethernet, be it pins or solder pads, It would mean I could get a mini, plus a rj45 with magnetics to go into a project im thinking about doing.

I am interested in knowing how many people would be interested in a break out for the mini with Ethernet? I have a design idea that can do that it will however only be 10BaseT.

I for one would love a mini with the Ethernet breakout (I can get an Ethernet jack with magnetics and LEDs for only an extra 50p more than a standard rj45 jack). 10BaseT would be fine for most projects, all you are doing is polling a server or serving the occasional webpage ( I am building a baker tweet for a friends coffee shop).

Just FYI...you can add native TCP/IP networking to the Netduino Mini using a SPI-based ENC28J60 module. If there's interest, we can publish a version of the firmware with this feature enabled. [Community member pascal06 did the work to make this possible.] Chris

[Adam Clifford]

Hi Chris, do you have a link to the post for that? would you just hook it up the SPI and call it in code like you would the N+? Adam

[Terry Massey]

thats the chip i was planning on using thanks to a hint from Chris. Walker. I have samples ordered to put the prototype together they ship on the 8th. Chris i would love to get that so I can test it out.

Hi Adam,

Best bet is probably to use the Olimex breakout for the ENC28J60 chip. Yes it uses SPI and yes you call code _exactly_ like the Netduino Plus.

pascal06 posted a bunch of thoughts on it, although I don't have a compilation of links handy right this moment. What we could do is put together a special build of v4.1.1 alpha 6 with the ENC28J60 networking enabled--if a few of you are interested in that. We could also make this an official "alternate" build eventually. My big concern is that you'd need to completely erase and reflash your Netduino Mini (to get a different bootloader on it)--so you'll need an RS232 connection from your PC to pins 1/2.

Chris,

you keep killing my dreams. however I was wondering if it supported PoE which would be great for industrial controllers who would be interested? I will open it like others by sharing the eagle files and pdf schematic and board layouts.

Oh Terry, sorry. When I say "best bet," what I really mean is "plug-and-play, what we've tested." You can wire up the ENC28J60 module directly as well...but if there are any required support components you'll need to add those too.

The PoE question has already been asked... I answered it here:

The tail end of this thread should give you everything you need to PoE-enable the N+
