Adafruit CC3000 Cad File Search
 

Hi guys,

I'm looking for a CAD file for the adafruit cc3000 wifi shield as part of an off-season project for our team. Does anyone know where I can find them, or if anyone already has them? I'm using PTC Creo, so .step and .json files would be preferable, but really anything is fine.

Thanks

I attempted using those TI-CC3000 based Arduino-shields and my experience was terrible. The firmware (as recently as Dec 2014) was still very buggy, and the free Arduino software library was (IMO) way too convoluted/complex for simple tasks.

I have switched to using the Edison modules on the Arduino-compatible carrier. It's not a bug-free set-up either, but after figuring it out, I am MUCH happier than I was when I was attempting to get the CC3000 shield to work, and be stable for long-term use.

The Edison's two big hangups for small robot work are slow interrupt processing (when compared to an Atmel-based Arduino) for sensors like fast-rotating encoders (cure this by using one of the tiny Arduino's as a coprocessor that handles intterupts?), and coarse PWM pulse width granularity in it's PWM outputs (cure this by attaching a PWM shield instead of using the built-in circuits?).

If you run into trouble with either the CC3000 shield or the Edison, let me know, maybe I can help.

PS: Sorry - I don't have any CAD files for the various devices.

Yocto isn't an RTOS... it's Linux. Check out the VxWorks based OS for the Edison. I think it's called Viper. I can't find a link at the moment but I know I got an email about it a while back.

I know Yocto isn't an RTOS - That (plus experiments) is why I cautioned readers about the Edison module's interrupt processing abilities. Having an RTOS isn't the only thing that determines whether a computer will do well at processing interrupts at a given arrival rate, but you are right that the OS architecture is a big part of the job (and don't forget that many (most?)(all?) Linux implementations can be customized to make then leaner and meaner (sometimes the off-the-shelf mods can include making RT deadline guarantee changes), if you like digging into that sort of stuff).

When I last checked, there wasn't an officially-supported RTOS (by Intel/WindRiver or anyone else)for the Edison's two dual-core CPUs or for it's third CPU (a Quark?). That was a few months ago, and things may have changed since I last looked. Do you have any recent news?

A colleague is attempting to use that third CPU for catching encoder interrupts for a project he and I are working on, but he hasn't declared victory yet (and he is travelling right now). He would be one source of info I could try to tee up for someone who wanted help. He says he is using info he got from Intel, but I *think* what he is using are preliminary APIs/libraries, etc, plus advice gotten through Q&A discussion forums.

PS: Don't forget that we should at least mention CAD files in each post in this thread. <-- I just did. ;)
