Tbh I've been really busy, not had much time to fly anything and with conditions being crap, hopefully in the new year I'll have some new projects on the go, mostly to do with HAM radio, will certainly fly again soon. FTR I hate FB too   :D Merry Christmas

This new display looks interesting it says its for the Crius V1 but Im thinking it may work on other multi wii boards to as the support is in the code and not so much the board  ~~

http://www.rctimer.com/index.php?gOo=goods_details.dwt&goodsid=797&productname=
I think I might get one just to have a play they are cheap enough and its a new gadget  ::)

Features:
•High brightness, self-emission, high contrast ratio
•monochrome 128×64 dot
•5V I2C interface
•Used for telemetry and debug MultiWii FC.

Other
•Dimension: 27mmX27mm
•Height: 6.5mm
•Weight:3.7g/4.9g(include cable)

Package content
•CO-16 OLED Display Module x 1
•4Pin cable 100mm x1

Arduino sources code : http://www.wide.hk/download/i2c_OLED.rar

[attach=3][attach=4]

CO-16 OLED connected to the Paris v3 FC Board:

Hi Gaza07,ive got one of these comming,I think with multiwii 2.1 the code is in there,not sure yet,your's,Marty.

Gaza07

Let us know when you get it Marty I fancy getting one to not because I need one but because it looks cool and is another gadget  :rolleyes:  ::)

Dont know if anyone has mentioned it yet they probably have but we love pics and video's  :whistling:

Wilfrid70

Hi everyone,
I just received one but I can't make it work. Screen remains black whatever I do. I've updated provided i2c-arduino code, with both old or new arduino IDE, program runs, debug is sent to serial but nothing on screen. It stands black as if no power (while 5v is present). Is there something supposed to appear on screen when powered on (even with no arduino) ???
Is there someone who could help or give feedback on their experience with this device ?
(I'm not using multiwii and even not able to compile it bit it's another story... No?)
Thanks in advance.
Wil

Hi Wilfrid70 and welcome to the forum  :welcome:
I am running this screen on a multi wii v2.1 quad rotor, and it works ok but some times the screen crashes, without multi wii I dont think the screen will display any thing, are you having problems setting up multi wii or are you looking to use the screen for some thing else ?

The file I linked to above has nothing to do with multi wii and you dont need it if your going to use the screen with multi wii, heres a video of the screen in use with the multi wii v2.1 firmware, It explains how the screen is used via the tx,
If you need any help setting up multi wii, just post in here what problems your having and will do my best to help you  ~~

Hi Gaza,ive got one sitting here,have not used it yet,what did you define in Multiwii 2.1,many thanks,Marty.

Wilfrid70

Hi Gaza.
I'd like to use the oled for some personal devs. I would use some multiwii functionalities as well but not for RC stuff.
My first need is to make work that screen or at least to know if it is not dead.
Is it possible to use Multiwii for that oled test even if I have no IMU or RC or Motor board connected ?
I tried the arduino stuff proposed for that oled (i2c arduino.rar), but no more luck...
Looking around I saw 2 potential issues. Some seems using reset pin but not available on the CO-16 (right?).
Else, it seems there I two possible i2c address for the oled (3C or 3B depending on SA0 ???).
What do you think ?
I couldn't found data sheets for that oled, would someone have a track for me ?

Thanks a lot

Gaza07

Hi Wilfrid I have tried the screen with multi wii and no sensors attached but it doesn't work so your maybe going to have to go through the multi wii code and alter it in some way to get around this, I have also looked at the code supplied on the screen manufacturers site and that doesn't work for me either, I will keep looking for a solution and let you know if I find some thing  ;)

Gaza07

Marty here's the lines in the config.h file that i have un-commented to get the screen working on multi wii, search for those lines and make sure they have the // removed there are other already defined just leave them as they are  ~~


#define LCD_CONF

#define OLED_I2C_128x64 // I2C LCD: OLED http://www.multiwii.com/forum/viewtopic.php?f=7&t=1350

Wilfrid70

Ok thanks Gaza. As we have the same result without full MultiWii board and provided code, I can at least expect that my screen is not dead, that already a big step for me ! :-)
Stay tuned !

Gaza07

I'm pretty sure the code stops until it gets a signal back from the sensors, so the screen doesn't get initialized and doesn't show any sign of life  :rolleyes:
please keep us informed if you make any progress with it  ~~

Hello,
I'm trying to extract core oled functions from MultiWii but there are ramifications everywhere !!!
Oled initialisation in Multiwii seems more complex than in other samples, but if it works it is maybe for such a good reason...)
However, I'll let you know.

One question although, did you tried to use only 3.3v VCC instead of +5v ? (Even if I tried with 5v and it is noted 5v on the board... but just wondering for future apps if one day it works :-))

Wilfrid

I couldn';t find this line: #define VBATREF 24,  where could I find it? Still can';t get my Crius OLED display to work, only displays little dots. Any help is greatly appreciated!!!

Hi Im afraid to say these displays are very unreliable and often just display dots, I have 2 of them and 1 does it more often then the other, rctimer say you should power off for a few seconds and then power up again to clear this but that doesnt always work either, when the display does work it is very good and you can edit your settings at the field  ~~

Hi Gaza07,

Thanks for the help but still not working. I have seen the screen work but only when connected via USB. I';ll wait till they';ve got the bugs worked out, going to try to get the Bluetooth module to work instead.

I have actually used the screen to change settings but its just to temperamental and just refuses to work at times, I think its a prob with the screens and not the code, I have a Android phone now and have the Multi Wii apps for that via blue tooth it is much better  ~~

Ross

Let's be careful out there.
SAFETY is.. NO accident.

Gaza07

I was looking at this on the wii forum the other day and was going to do the fix to mine but to be honest the screens are crap and you can buy other brands and they work fine, not sure I will ever use it  as I have blue tooth on my quad and connect with the android wii app :hmm:
