Hi Mattster,

So I should be able to plug to NGo main boards together with a GoBus cable and get 21 mbits between them?

Theoretically yes, although this would be an advanced hack. If you try this, be sure to shut off the power to the GoPort on both boards so that they're not trying to power each other. You'll also need to implement SPI Slave for the second board.

To set your SPI clock to 21mbps, you can use a SPI clock divider of "HSE/8".

Thanks Chris. We're playing around with some ideas for distributed processing. Is there any faster interconnect available for the NGo?

The 21mbps GoBus SPI transport is probably the fastest option, followed by TCP. There may be ways to amp that up a little bit.

I think the fastest interface available on Netduino Go microcontroller is the High Speed USB. Then Ethernet, followed by SPI. The theoretical SPI clock frequency limit is fPCLK/2, its major advantage is that it is full duplex without any protocol overhead. Also the UART interface provides a special multiprocessor communication mode with automatic address detection, but the speed is limited to fPCLK/8 (8× oversampling).

The maximum clock frequency of the high-speed, resp. low-speed APB domain is 84 MHz, resp. 42 MHz.

Oh man, we need a party! And invite a few thousand Netduino Go users over as guests :) We might have to find a bigger space. Chris

This is an off-topic response.

 

First, I was delighted to see your product, reviewed the documentation and ordered the Starter kit from "Maker SHED".

 

I think you have a great addition to the gadgeteering class products with some enhanced functionality being that much easier to implement with SPI and smart peripheral boards.

 

That said, sharing the UART2 and UART4 with SPI1 and SPI2 across multiple sockets has its limitations. Granted, the gadgeteer sockets suffer from similar limitations but overall there are more raw I/O exposed on a gadgeteer board making some socket combinations more readily usable. In addition having to use a second micro to communicate with any devices is going to slow things down compared to a gadgeteer solution.

 

I look forward to your next offerings and wish you all the best.

 

Dennis

Hi Dennis, Welcome to the Netduino community, Netduino Go uses virtual I/O, rather than the more limited pin assignment setup used by Gadgeteer and other components kits. The UARTs and SPI buses split between ports are there to enable the virtual IO...rather than being used for raw IO. Of course, you are certainly welcome to hack away and use them as raw IO for custom purposes. Chris

Happy anniversary to the Netduino Go

 

One year further again and lets us all hope that the promises made in the first post is going to be reality.. with some more modules to follow.

 

Cheers Olaf

A quick note...

There's new stuff coming, and a lot of new gear that's been designed over the last two years which is ready for or going into production now. But there are a lot of moving parts...so we're probably going to wait until things are available for sale before making announcements.

It was a lot harder than expected (both for us and for launch partners) to ship the early hardware--so we've rethought things and built a plan around getting some good first-party hardware out there first and foremost. Thank you all for your patience on the GoBus gear; we're pretty excited for the new gear which will be shipping this year.

Chris

P.S. Dang Mouser; they weren't supposed to list those new modules yet, especially not with the prototype-sample photos... We'll have to get the photos updated, at minimum.

Hi Chris,

 

Thank you for locking the other "Farewell" topic so I can not thank you for responding there.

 

Are you going to read the personal message I sent you last week ?

 

Is there any possibility to have the Go Hub / Gadgeteer adapter physically in my hand?

 

I require a design where multiple relay boards and current measuring equipment run along side and the space where it is going to be implemented is very tight.

I do want to use the Netduino GO because it would be exceptionally beneficial to have plug and play hardware.

 

I can pay for the modules and shipping but you don't have to do magic they don't have to be functional it is all about pre-design.

 

This is my last effort.

 

Best regards,

Olaf van Schoten.

Hi Olaf,

Sorry, didn't see my new PMs. You have PM :)

Thanks as always for your enthusiasm and support,

Chris
