Sorry to hear that, is it possible to downgrade the module by installing factory firmware? I noted what you said about extending the cc3000 pads.

Wow, that is just so cool, you are a wizard! That was using the managed driver, yes?

I was simply thinking of the current draw (but used the wrong term) and given it's 3V3, it should be practically the same thing.

Sure, you'll all be able to have you're saying about it and yes, I can put the Eagle files on CodePlex or elsewhere later on. Just so that you know though, in couple of days I'll be going away for a week and I'm pretty sure the design won't be ready until after I get back.

Don't worry, I won't use anything smaller than 0805 or I can't solder by hand. I suppose the CC3000 will require re-flow but even so, placing will be done manually.

SmartConfig is rather nice. I got a couple of AirportExpress units and I could configure those from my iPhone without having them wired or even being on my wireless network. I'm not sure that is the exact same thing but I guess in essence. Finding that iOS app was almost too good, sometimes you are either lucky or happen to think the same way as others did. Ruling the universe is no biggy, it's simply a matter of wanting for the right things to happen :-)

Hi guys, I'm back from my holiday now and was looking forward to work on the PCB that I set out to do in Eagle, but... While I was gone, my commercial IO board launched so I need to attend to that in improving the software, writing docs, creating sample projects and so on. This means I won't have time to work on the PCB for a good while. I'll be happy to see someone else pick it up instead and since I didn't get farther than removing the mosfets, there's little point in me posting the Eagle files.

BTW, the monster dac is still playing just fine ... although now controlled by jremote from an ipad via an pc/usb. Like to have that changed into some embedded solution ... but with those rates .... do not know if that will work ... time will tell ....

Ah yes, any new pictures of that monster of yours?

 

The driver for my wifi module is far from complete, it can scan for nearby wlans, connect over dhcp and ping other hosts on the network. I'm currently working on the UART variant but will switch to the SPI version (PCB supports both) when I get the hang of it.

It's based on the RAK410 module, specs are here: http://www.rakwirele...0_Datasheet.pdf To the left is a PeekyPokey used to explore the API since it's more conveniant to do directly from the PC. When I'm done, I'll move the code to the Netduino.

Ah, over air firmware updates - cool!

thx 4 the fish.

What, are you leaving this world for another planet so soon? ;-)

That is some great work there!

 

I saw your other post about LEDs and there will be plenty of time to change the design before manufacture.

Anyway, I started working in Eagle yesterday but didn't get much farther than removing removing mosfets and moving some passives closer to each other. Naturally, you'll get to give your input when I get something to show. Oh and also, I removed the proto area.

I think I just fried mine  Seems pwr_en is ground and it's supposed to be an input...

your radio or host board?  I've flicked pwr_en high and low just fine, so maybe double check the wiring, maybe it's OK!

The radio, when trying to set the pwr_en input pin high by applying 3.3V to it, it seems to result in a short circuit.

Darn, I managed to submit twice so please disregard of this post.

Exactly, why on earth did they choose to add custom headers with 2mm pitch as an alternative to the special headers already being odd? I'll give it a try too, using SPI bit banging of my very own USB board as to challenge you all in this quest for fame and glory. Saddle up there, oh bretheren fore once again we shall ride blindly (and stupidly) into the unknown.

Sorry to hear that, have you tried the Texas E2E community?

 

They are very helpful and you usually get help directly from TI employees working within the very field in question. At one point they even called me on the phone and that without me having pretended to be a big shot with 1k+ units planned for production 

I did try the dead chicken routine but nothing in particular happened (other than our old parrot arising from the dead which was kind of freaky btw).

 

I too have a Bus Pirate laying somewhere, still untouched since I use the scope instead, it works pretty ok for me.

 

Vdd is 3V3 but I might have accidentally applied 5V logic at some point effectively killing the pin (I'm using my own USB explorer board, not a Netduino).

 

Btw, are you also using the older TiWi-SL eval board from LS Research?

I soldered short wires onto pins 7 - 12 on both the J4 and J5 headers (and left all other pins unused), then stuck it down a regular breadboard.

 

 

 

@Valkyrie-MT: Great to learn you've joined this party!

 

I was under the impression those structures were actually pretty well documented.

...or am I missing the point here?

 

EDIT: At the time of writing, I noticed that the TI wiki seems to be having some problems but the links have worked before so it's probably just a matter of time before the problem is solved.

 

EDIT: Links are ok again 

Extremely off topic now: The triangle of binomial coefficients, a.k.a. the triangle of Pythagoras perhaps? But what about monday... EDIT: I'm so stupid, 29 as in your nick will go lay down now. A miscalculation, sleep well! EDIT: Nope, wrong again I think. I actually came to think about the tower of Babel and then found out about Ziggurat: http://en.wikipedia....urat_at_Babylon It was not until I saw the tower that I realized that your avatar depicts it. The number 29 according to the formula has probably something to do with the dimensions of the tower structure. This does not solve the riddle but interesting never the less. I have to give this some more thought and a bit of reading. I find these kind of things highly interesting. Sorry for all the off-topic stuff here guys.

Hmm...now I can't sleep trying to figure that one out :-)

Looks like a nice board!

 

Yeah, the 5 x MOSFETs translate to and from 3V3 and Arduino 5V respectively. For Netduino projects they're not needed at all but there are hex converters if Arduino compatibility is required. There are some alternative pin routing that can be omitted as well.

 

Personally I wouldn't be soldering stuff onto such a fairly expensive board so I would put a standard 0.6" DIP24 IC holder for you know what (with the corresponding pins routed) instead of that prototyping area.

 

I don't see a 2.1 mm barrel connector for external power and I'd like to be able to use an external antenna so a uFL connector could be added.

 

If you guys like, I could tinker with a slightly different board incorporating the modifications suggested above or differently if you think otherwise would be better. I'm no RF designer but the mods would be quite small except for maybe the uFL connector.

You can usually ignore those warnings, vendors typically stress such things on samples to maximize the probability of users achieving success in evaluating the part. I'm pretty sure you can leave the bag open for years and it will still work and yield an ok product for hobby purposes.

A $20 wifi board is great value, especially for a single unit!
