Thank you, it wasn't. I had forgotten the oledSetTextColumns() call. Fixed it, thanks for the reminder/help.

@Radovan-Behýl Please try to study the official Onion Omega2 Documentation carefully. OLED Expansion Using the OLED Expansion OLED Expansion C Library OLED Expansion Python Module

@Ericke-Rafael-Gallardo Please check your other post

@György-Farkas wow! Thankyou so much! I just got mine. I had fun testing it. I'll try this schematic of yours. Probably I'll post an update if this works. 0_1537628167095_6CFB40DA-697B-45BF-9D42-29611FC35D24.jpeg

Thank you. At least now I know why it isn't working maybe some rainy sunday I'll try to look into the code and fix it I have some experience pulling json data like this for other projects on ATMEGE328p and ESP8266. The Omega is almost overwhelming me with all the features and coding options, but I like it. I made the newsfeed work instead and will adapt that into to train time display for my husband. Good to know I wasn't just messing up.

The display you linked is for the Arduino Mega board and would not work with the Onion Arduino dock 2, as it is based on the Uno not the Mega. You could have a look at maybe a usb type screen like this one: https://www.dfrobot.com/product-1062.html which seems to support OpenWRT.

Thanks for that! I cleaned those mistakes up and its running properly now.

@György-Farkas my OLD have 7 pin. but i know how to configure this one to I2C interface . thank you.. problem is solved..... image url)

So I managed to rotate the screen 180 degrees but getting the text to read left to right is giving me a headache. Text displaying backwards now from right to left mirrored but bitmaps etc display correctly. Looking at other arduino/esp libraries i followed the same init sequence but no luck: sendcommand(0xA0 | 0x1); //SEGREMAP //Rotate screen 180 deg //sendcommand(0xA0); sendcommand(0xC8); //COMSCANDEC Rotate screen 180 Deg //sendcommand(0xC0); sendcommand(0xDA); //0xDA sendcommand(0x12); //COMSCANDEC Anyone familiar with the onion oled library that can point me in the right direction?

@Douglas-Kryder i figured it out, i have to use vim.

Onion sent me a new OLED, and I'm happy to report that it is working just fine. I didn't change anything else. If I get time, I'll try to debug whats wrong with the original one. Suggestions welcome. I did notice that when with the new OLED, when I do % oled-exp -v So the value changed from 0xff to 0x03. Not sure if that matters. Thanks to everyone who tried to help out. Appreciate that.

In my case it was a desktop watch so logically it was powered on 24/7. OLED displays are not like CRT. CRT tubes only decay when there is a long exposure to the front phosphor so as long as you do display changes (like screen saver) screen will be fine. OLED displays does not work like CRT. Each OLED pixel has a short life span when powered, so doing 'screen savers' will not work as they will still power on the pixels. Will last a bit longer, but the OLED display is condemned since is power on. The only good solution would be as you said, is having the display off, push a button, display info for 10 ~ 30s, then power it off again.

@Kit-Bishop Thanks very much, Kit. Looks like a good start. Hope Onion makes it official.

@Luciano-S. Right. I read that. I have a 3rd party LCD display I got working with the links I gave. https://www.amazon.com/gp/product/B01GPUMP9C/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1

Great project! Very useful, thanks!

They haven't responded to my ticket at all Just completely ignore it for a month.
