Netduino as I2C slave?

01 July 2012 - 02:14 AM

Hi All... I was reading the data sheet for the uC used on the Netduino and I saw that it has 1 I2C port, and the data sheet says it is master only. Does that mean that it is not possible to use a Netduino as an I2C slave device? If it is possible, how is it done? Thanks...

Very basic questions...

27 June 2012 - 05:08 AM

Hi All... I have done a lot with Arduino, and I have many years experience with CC/C++, Java and other language development. But, I have no experience with .NET. In Arduino, everything is done with libraries. There is no RTOS of any type. Is it correct that with Netduino there is also no OS? Also, does the .NET framework provide libraries or APIs for things like SPI, I2C, Serial/UART, EEPROM access and so on? Or do I need to find various libraries for these features? Finally, what's the difference between Netduino, Plus and Go? I see the Plus has enet and an SD card socket. But what's the Go? Thanks very much...

Embedded web server hardware

27 June 2012 - 04:58 AM

Hi All... I am investigating how to do a project that seems very similar to what is being built here: http://forums.netdui...ost&f=15&t=3649 I need to build a circuit that will accept data from a host system via I2C/TWI, then publish it with a web server via wifi and blue tooth. Clients are cell phones and tablets. The web site must be AJAX capable, ideally compatible with M-GWT or a similar toolkit. I was originally thinking of doing this based on Atmel UC3, perhaps with FreeRTOS, but it seems I could use the Netduino board design as a good starting point and have a nice powerful ARM uC. I would then add a wifi module and a bluetooth module, and perhaps some SPI accessible flash to hold the web content. Does this seem to make sense?

Porting Arduino code to Netduino

30 April 2012 - 09:57 AM

Hi All... I just ran across this project and its very, very cool! I have an "Arduino" project running on a custom board with a 1284p processor. I'm about at the limit of what I can make it do and am looking to move it to a 32 bit platform. I noticed that Netduino uses a 32 bit Atmel processor. I googled on this, but no luck... Is there any reason the AVR-GCC toolchain could not be used to target this processor, thereby enabling Arduino code to compile and run on this processor? People here have said that the "Arduino language" is a simple C or something to that effect, but in fact its a full implementation of C++. And while C++ can be ported to C#, given the libraries I used (I2C, A serial communications library, an SD FAT card library) it seems like that would be quite a bit of work... Of course there would need to be changes related to 8 bit vs 32 bit and such, but if AVG-GCC could target this processor, wouldn't that be easier?
