Hi all, I hope it is ok to post for sale messages here. I backed the omega project because well it is a great platform, but I never got beyond doing "hello world" type work. Most of the kits are still in their boxes. Love to have this go to someone who can use it.

I posted a for sale in my local craigslist (Boston area) but I am happy to ship this to someone in the CONUS as well. See the CL post for pictures and what's include please:

bump... anyone??

I am writing a high level output library on top of the python oled-exp library. Can someone explain the scroll behavior for me? I have a virtual buffer of characters that I want to write to the display and scroll the output. The current scroll call seems to start scrolling and I have no way to control how many columns before it stop. Calling scrollStop just stop the scrolling when ever the call execute.

Ideally I want a scroll by N column call. Is that possible?

Thanks,
P>K.

Thanks @Bryan-Hilterbrand and @Lazar-Demin - I have to update both libraries. Now it is working. BTW this is my package list:

libonionoledexp - 0.2-1
oled-exp - 0.1-1
pyOledExp - 0.2-1

oled-exp is still at 0.1.-1.

P.K.

Hey @Lazar-Demin did you see my other post? The python library is seg faulting on setting pixel column, and the doc has typos in it.

These are the packages I installed to get things like HTTP request working:

• okpg install python-light
• opkg install python-codecs
• okpg install python-openssl
• okpg install python-logging
  And for the various expansion:
• pkg install pyOledExp

As you said there is no room for full python.

I am go glad you updated the oled python library. HOWEVER:

1. there are typos in the wiki: the python method is not oledSetImageColumns() , it is just setImageColumns()

(one can check by doing a dir on the module)

1. more importantly, when I call setCursorByPixel(0,0) I get a seg fault.

Please fix these bugs ! I am writing a library to write scalable font to the display and need byte level writes to work.

Thanks,
P.K.

I am trying to write a better oled library, allowing for scaled up characters. However I just realized that the current exposed API has not write_byte command to just output one "page" (8 bit) to the display. Can you add that, or a setPixel call, so that we can do better output to the oled display? I see that on github you have a old raw python to i2c library. Does that library work? That maybe a faster way to implement something more powerful then your current python wrapper.

Thanks,
P.K.

according to the documentation the oled write function will handle newlines in the input string to advance the cursor to the next line on the OLED display. But it does not work for me. Is this is know bug?

Quick test program:

from OmegaExpansion import oledExp

oledExp.driverInit()
oledExp.clear()
oledExp.write('line 1\nline 2\nline 3\n')

does not result in three lines.

Love my Omega -- but why does this community board using a max amount of CPU on Chrome on OSX?

P.K.
