Changed it to default-on and it's on now. Thanks for the directions

It's happening on the minidock.

My led on the omega onion module started blinking after it's being up for several days now. It's not a problem as far as I see, since all is working as it is supposed, but still, it's happening on both modules I have. Is it a power issue warning of some kind or is it a warning for something else? Does anybody knows? Thanks

Try this.

I think i've found a few weeks ago something on ebay, try searching by 2mm header and you'll find a few hits.

I believe that SPI can't be used in ómega since it's been used for the memory chip already. Please correct me if i'm wrong.

edit /etc/rc.local
add a line with python </path/programtorun.py>
save file

Did you try python-light? I'm running ómega with python and a few bits and still 53% available.

HD3000 from Microsoft works ok with mjpeg-streamer

If you run BP180.py you'll get 1sec readings of temperature and pressure. I've changed it and now if i run it on background (python BMP180 &) it actually writes the values to 2 files, calle pressure and temp. This way i can always check the values using cat temp and cat pressure in the command line.BMP180_V2.py

Hi Luis, try the last two links on that same post, they should work

Have the same issue with HTU21D, fully detected by a Rpi but no detection on omega. But on the other hand i have another HUT21D that is detected normally. Since both cases they are assembled in tiny boards i've bought on ebay(they came from china), i suppose that the ones that are not detected may have the pullup resistors for SDA and SCL missing. Didn't loose much time on that but i do believe that omega doesn't have internal pull-ups as the Rpi, so the problema is shown in one side and not on the other.

(pin 20 is SDA and pin 21 is SCL on this last)

0x3C is the i2c address of the oled module, nothing to do with pinout

Should work by wiring SDA and SCL of the display with the same pins on the omega. Supply is usually 3.3V for those modules. I have one of those and did the same and i2cdetect shows address 0x3C if i'm not mistaken.

Try this pythoni2c.py

I've developed a few basic python routines for i2c you can find them in the file pythoni2c.py

Why don't you use ssh to access you omega? What i do is that, edit the python files with nano, and run them on command line. Simple and effective.

Notepad++ is what i use under Windows for editing such files @Kit-Bishop
