cc3000 and LED backpacks - not working

Post by wwhite74 »

orderd a bunch of stuff, some i can get to work some i can’t
neopixel ring and RTC module, up and working fine.
cc3000 and alpha led backpack, not so much

pictures here - https://www.dropbox.com/sh/22txnzcb07s3 ... NHWPa?dl=0
when taking the pictures i noticed there’s a ton of flux, don’t know if that’s the problems or not.,

LED Backpacks - don't display anything, I ordered 3, i've assembled 2, holding off on the last one till i figure this out


cc3000 seen several posts about this, i'm having the same issues
it get the first few lines, then hangs after "Initialising the CC3000 …” I tried turning on debug, and it gets a few lines and then hangs
I’m using a 9v wall adapter to power the arduino, getting the 5V for the cc3000 off the arduino.

Code: Select all

RX Buffer : 131 bytes
TX Buffer : 131 bytes
Free RAM: 1215

Initialising the CC3000 ...
	CC3000: init_spi

	CC3000: Finished init_spi

init

start

	CC3000: SpiOpen	CC3000: WlanInterruptEnable.

	CC3000: Finished SpiOpen

	CC3000: ReadWlanInterruptPin - 001

The debug code throws off the chip timing and basically makes it impossible to get a network connection. Go ahead and turn that off again.

WRT the LED matrices, your soldering and connections look okay, but let's make sure the signals are getting where they're supposed to. Check the voltage between the '-' pin and each of the '+' pins for starters.

i only tried the debug when the regular didn't work, It's back off now, and still not getting past initializing.

voltage is 4.9v
currently running off the 5v pin on the arduino (arduino is running on a 9v external adapter)
I've only plugged in one display at a time

I'll jump in here instead of posting a new topic, as I am in a similar position on a brand new CC3000 shield that can't get past that same initialization message.

Powered by Uno 5V running on a 6V 2A adapter.

I read all through this: http://forums.adafruit.com/viewtopic.php?f=22&t=57592 but strong power fixed that.

@wwhite74:

The CC3000 does act flaky when it doesn't have a strong enough power supply. How much current does your 9v adapter provide?

WRT the backpacks, I missed something obvious when looking at the connections: you have the data and clock pins connected to the Arduino's digital pins 4 and 5. The chip that drives the display uses I2C though, and needs to be connected to the Arduino's I2C pins: A4 (SDA) and A5 (SCK). Move those connections across to the analog header and see if that helps.

I"m using the 9v 1a adapter that you guys recommend
https://www.adafruit.com/products/63

and hooray, thanks!!
missed that, it's my first time messing with arduino
Both LEDs work now, i'll solder up the last one when i get home

Glad to hear the LEDs are working for you.

WRT the CC3000, I'll need to pass this over to someone who knows more about the chip than I do.

it's been a while, but i finally got time to get back to the cc3000

reflowed all the solder joints today, Tried the build test sketch and got nothing,
Tried the NTP sketch just to for kicks and it initialized.

re-ran the buildtest and it's working now.

so not sure if something in buildtest is wonky or what happened,

----edit----- upon more testing after it stopped working again.

seems to be power related...
i'm using the 9v 1a power supply for the arduino, and a 5v 2a supply to drive some pixels and segmented LED displays.
(arduino ground pin connected to 5v ground on the bus for the other stuff)


USB powered arduino + cc3000 power into arduino = works
9v powered arduino + cc33000 into 5v supply = works

9v powered arduino + cc3000 power into arduino = no works
USB powered arduino (with 9v plugged into arduino, but not the wall) + cc3000 power into arduino = no works

Yeah, we know power is an issue with the CC3000.

The best suggestion I have is to find a setup you like where all the hardware works.

I was able to get everything up and working, although have decided the cc3000 is not the solution for me.

the 2 main reasons being it paused code execution for 10 seconds to retrieve a web page, and taking over 10 of the 32k of program memory

went with an electric imp, (bought from adafruit, but used sample code from elsewhere)
Was up and running pretty quick, and with the imp hardware handling all the wi-fi grunt work, it's much quicker, requests are nearly instantaneous, and don't slow down the blinky things the arduino is driving.
