I’ve used a MAX485 chip to talk to a Mindstorm NXT before over its high speed serial line. This shield looks easier to use since there is no custom code that needs to be written (just use SoftwareSerial) and you can set what your TX/RX pins are with jumpers.
News - Enginursday: Developing o…
You need to buy a breakout board. Sparkfun made ones will have a variety to chose from but right now they are mostly on pre-order. There are two Intel break out boards you could get today: the Arduino breakout board and the Mini breakout board. I bought the Arduino breakout board from Makershed and the mini breakout board from Mouser (though I just discovered it is still on backorder).
If you don’t have the Edison yet then order the whole thing from Makershed or Mouser. Mouser has the whole kit (break out with Edison) in stock.
I’ve set up the Eclipse environment under Windows 7 and it works but there are issues. In particular the remote debugging. It started out alright but now it refuses to show me any variable values and often times it just simply refuses to allow me to step through the code. Not at the board at the moment so can’t remember the error it returns.
News - The Edison is Not a Raspb…
Everything you said is true for really serious robotic development. I don’t think Intel is targeting that however with the Edison are they? The are more about marketing to IOT and wearables with the Ed (at least that is what I’ve seen on their website).
One thing they both have in common is the lack of documentation (or the disorganized way they post their documentation) when both came out. Seriously the Edison guys confound the masses by first showing how to get the “Blink” sketch to work and then post next step links that are all Native C++ code. Huh? What??
How do you go from Blink to showing IOT development with Eclipse and GDB?
Wait….the video states bus lines can support 3.3v-4.5v devices. The description above says it can “ level shifting it from 1.8V to your sensors voltage.”
So which is it? And is 4.5v really the max? So if I were to hook up an Arduino as an I2C slave then that would not be a good thing.
Maybe it is just me but I hate it when pullups are added onto I2C devices. Some sensors have pullups on them and they just cause problems if everyone pulls up the damned I2C bus. I even turn off Arduino’s pullups on the SDA/SCL line. Sorry for rant.

I don’t think some of the people below read the article. A CRC checksum is performed after upload which is a pretty good verification that the code integrity is correct.
I recommend turning off verify code after uploads during development for performance and then turning it on for your production release.
Thanks for the article.
Er… most of that would get caught by the CRC checksum.

Put the soldering iron down or the chip and kiss get it.
