Bug Filed on 07-08-2016: Incorrect Association of Extension with Serial Bus 1

Bugs / Issues
1

What dashboard are you using? I am using the online version of Cayenne though I noticed that I could circumvent the problem using the iOS version of Cayenne.

What OS? I am using Jessie

What Model Pi? Raspberry Pi 3

Please describe the bug / issue. Attaching any relevant screenshots would be very helpful!

I am trying to interface Cayenne with an MCP3008 ADC and trying to add it as an extension to serial bus 0. However, after a few tries, it kept associating the extension with serial bus 1. I tried creating the extension on the iOS app and I was able to successfully accomplish association correctly there. I checked the circuitry of my RPi and it was correct. Do you have any idea why this was occurring? Thank you - I will patiently wait for the day when I can remove the extension associations to serial bus 1. :wink:

Yours truly,

Jacob

Jacob,

Welcome to the Cayenne Community!

I thought I had noticed exactly what you described here last night while I was working with @frederic here-

So I wanted to try and replicate exactly what I thought I saw and what you saw. So I re-imaged an 8GB uSD card and went for it. So I started with a new image of 2016-05-27-raspbian-jessie.img and did the usual localisation housekeeping and loaded a new instance of Cayenne on a RPi3b. I already had the circuit built with the MCP3008 pin 10 (CS/SHDN) jumpered into physical pin 24 (GPIO8/SPIO_CEØ_N) on the RPI as can be seen in this photo with the brown jumper.

I then added the MCP3008 to the RPi in Cayenne as indicated in the below screen capture-

So I’m plugged into CEØ and I selected SPI Chip-Select 0 and low and behold it populated the Extensions window on CE1-

So, yup I saw what I thought I saw, and Jacob confirmed it! So we will pass this on to @bestes so he and the crack team at Cayenne can do what they do so well.

Good catch Jacob, and again welcome to the Community,

Ian

Thank you so much Ian! I am glad I could catch it! If I see anything else while working, I will let the community here now!

So… Just wondering… Does that mean I get a badge for spotting a bug that was confirmed? Like you know, something like “flyswatter” or “bug zapper”? :grin:

Also, did you also try running it on the iOS app of Cayenne to see if you could replicate my results (meaning the circumvention of the problem)?
