@Don--White also, i just discovered that the dec update on kickstarter was added to the indiegogo site on 1/3/19 so the 2 platforms seem to have basically the same info now except for comments by backers. interesting to me is that kickstarter restricts access to the updates for non backers of the project thru ks , but indiegogo does not.

@Michal-Dobrzynski Please do not forget to remove the pin3-pin4 short circuit if you want to plug the Oled Expansion to any genuine Onion Omega Expansion Board Header directly because Omega2(+) may be damaged if you set GPIO11 to Low.

There are I2C level shifters on the OLED Expansion.
Pin4 of the Expansion Header provides the voltage to the lower voltage section for those level shifters.
But pin4 of the Expansion Header is connected to GPIO11 on the Omega2(+) board.
So @Onion must set GPIO11 to High (~3.3V). It's a hidden simple hack that @Onion forgot to mention for example here.
You could find some further technical details here.

so, Don, do you have any particular question about the onion products you would like to ask?

@Lazar-Demin hello! what's up with halloween contests? You promised to publish the results on November 9))

@Ericke-Rafael-Gallardo Please check your other post ;-)

Apologies, I know this is an old thread but I have followed Paul Cousins instructions too and also have the "Connection refused" Error. I have tried to check that I have put the certificates over in a couple of different ways but as I am downloading them from Amazon to a mac and then uploading them to the onion, I'm not sure how I could be disturbing them.

I have looked for others having this problem and I don't see anyone so I'm really confused to know what I might be doing wrong.

Any chance you can say any more about why reinstalling the certificates worked for you?

Many thanks

Robin

I believe you can turn indexing off by going to:
/etc/config/uhttpd

and changing option no_dirlists '0' to option no_dirlists '1'

If the directive doesn't exist.... add it.

I have exactly this problem. I moved the omega2+ to a similar computer. Both have ubuntu 14.04 LTS. It works OK on one but not on the other.

@György-Farkas Thank you very much for the assist...it was very helpful.

You need a arduino library for ws2815 led strip,you can study it from here.

@Alvin-chan
APA102/APA102C has disappeared....the SK9822 is not an exact clone of the APA102. It adds some interesting features. For example the programmable current source to control global brightness and a non-staggered update. But there are also some drawbacks like the protocol incompatibility and the lower PWM frequency...
Obviously APA107 is best choice with higher PWM and lowest price.

Solved it! I was trying to run the executable by using a dot and a space (". hello") instead of "./hello". Executing by the method i had no problem running the program.

@William-Scott
I do not know how right this is, but it works:

import os def temp(temp): temp = os.popen('cat /sys/devices/w1_bus_master1/28-0000053f7e76/w1_slave').readlines() temp = temp[1] temp = temp[29:34] temp = int(temp) temp = round(temp / 1000, 1) print('Temperature :', temp) temp(temp)

Just for some reason, rounding does not work
