  Thanks for all the nitty-gritty details, @Gordon!

  About the timer: are we sure this isn't doable? I'm not familiar with the terminology, so I'm not sure what to even Google. The Broadcom datasheet implies there's a timer, but I don't know enough to see if it's the "right kind" of timer.

  I was wondering if there was any more work done on this issue.

  As someone just starting out in the embedded space, I can testify that the Pico has a much better beginner experience than a Raspberry Pi, especially for JavaScript.

  I can put some work in on this issue... I like the idea of DietPI that boots directly into a Espruino prompt that can be programmed using the Web IDE.

  Besides the timer issue (BTW, here's the Broadcom datasheet for the Zero), anyone foresee any problems?

  Yeah, works great! I'm using custom pins and everything.

  Thank you, you're awesome.

  espruino_1v85.139_pico_1r3_bootloader.bi­n successfully flashed this time, yay!

  I tried almost everything I could think of, including:

  1. B3-B8
     
  2. B3-B7, A8
     
  3. B13-B15, A5-A7
     
     

  Just for the record, what's the proper syntax for .connect():

  var wlan = require("CC3000").connect(SPI2, A7, A6, A5);
  

  ....or....

  var wlan = require("CC3000").connect(SPI2, {cs:A7, en:A6, irq:A5});
  

  Thanks so much, @Gordon! :)

  Sorry, @Gordon, no luck with espruino_1v85.139_pico_1r3_bootloader.bi­n either. Same result: red LED stays on.

  Any ideas? I don't think my Pico is busted, because I just flashed it back with the regular firmware, and works fine.

  There's a weird non-printable character in the URLs above. (To give credit where credit is due, I used https://hexed.it/ to inspect the URLs.)

  But, anyway, http://www.espruino.com/tmp/espruino_1v8­5.139_pico_1r3.bin doesn't seem to work on my Pico. :( The red LED is on when I plug it in after uploading the firmware, and the Web IDE can't connect to it (the Ports list is missing the Pico, even).

  Any ideas? Perhaps I flashed it wrong? I can upload a screencast, if that would help.

  Wow, you're awesome, @Gordon! Unfortunately, http://www.espruino.com/tmp/espruino_1v8­5.139_pico_1r3.bin doesn't seem to exist (I get a 404).

  I can't wait to try it on pins other than B3-B8. :)

  Thanks for the quick reply, @Gordon!

  Unfortunately, setting up SPI1 doesn't fix it (that would be too easy). A .connect() call with no args always works, but .connect(SPI1, B6, B7, B8) always hangs, whether I set up SPI or not.

  At least now I know I'm not going crazy, and this is actually weird.

  I'm thinking of just getting an ESP8266, unless there's WiFi module folks recommend.

  Hi everyone!

  I'm trying to use my Pico + CC3000 using non-default pins (not B6-B8).

  In failing to do this, I tried just this:

  var wlan = require("CC3000").connect(SPI1, B6, B7, B8);
  

  ...which hangs!

  But this:

  var wlan = require("CC3000").connect();
  

  ...works great! Takes about four seconds.

  Am I using the API incorrectly?

  Thanks everyone!

  P.S. I tried this too:

  var wlan = require("CC3000").connect(SPI1, {cs:B6, en:B7, irq:B8});
  

  Also hangs.
