Test results?

[lukeweston]

Apologies for the "issue"... it would be nice if GitHub "comments" were a thing without actually opening an issue.

Have you actually tested this board? With success?
What software are you using? What microcontroller platform?
If using a microcontroller with 5V logic, what kind of translation hardware are you using?

Hi Luke,

I've built three of these boards and all have worked. I used them to work on my CC3000 code -- the test program, the initial port of the TI library (now abandoned since Adafruit's is much better), and the firmware upgrader. I also have the TI CC3000EM that I used for initial development and the Adafruit board to make sure the software problems were an issue with the CC3000 itself and not my circuit.

For software -- I'm using the base ATMega328 Arduino platform for testing etc. but most of my work is done using the Teensy 3 and Teensyduino. I initially used the TI MSP430 to make sure TI's code actually worked.

I did test the 5V Arduino communicating with the CC3000 using simple resistor dividers and the TI TXB0104 logic converter. As you can imagine the converter gave better & more consistent results, but the resistor divider worked for the test program. There was no special reason I used the TXB0104 over other chips; that's just what I had lying around.

I haven't done much with the CC3000 past that yet. I'm working on a project that requires WiFi and used these boards to prototype that, but I'm currently working on other parts of the design. The CC3000 is in a weird nebulous place right now. Everybody's having problems with it and TI doesn't seem to be very aggressive in fixing things. So...while I'm using the CC3000 in my project prototype, I may not be using that module when it ships (ETA) this summer. We'll see how this plays out.
