Does anybody know anything about that cute little screen ?
robotshop.ca/4d-systems-stamp-sized-intelligent-oled-module.html
It is small so it look easy to install on a robot to show some info… !
But how it is to make it work
Looks like it has a serial input so I’m thinking it would act like an LCD just more options.
Tanks
I think i will get it tomorow !
A lot of info online. Can send simple serial string. Will post when i will be on a computer.
Ok look realy interesting

Here an exemple of code of another forum for this screen. Only the part to talk to the screen is important for me.

As far as i know it look realy easy to use.
Looks like a neat device, the code looks quite simple , I noticed in the comments that it addressees row column, font ,color etc then string$ that looks straight forward.
Even for someone like me… lol
I will have it this PM and will post some info and video of basic command when have it… 
I think I could use one for a visible voltage monitor and such on my bot…good eye candy and useful.
I look forward to your evaluation when you get it.
Got it to work hook to a PC.
I have made a custom software just for test.
Uploading the code now.
Communication is done and i have the value.
Now i need to hook some potentiometer to the BB and show that.
Any info about wiring a potentiometer, and the line of code ?

sorry for the worst than poor quality video… iPod video…lol
It’s alive…!
I just made a picture.

The screen is realy good. But i wonder if i can have everything hook at the same time… Since i need Seria for SSC-32 + Screen and pins for PS2 controller. Any advice there to hook all that to the BotBoard with BasicAtom Pro 28 ?
I’m not positive but I think you can output serial TTL on other pins of the Atom Bot Board.
Yes, true any I/O pin can send TTL serial data.
Tanks Robot Dude and Putt Putt,
That’s realy cool to know, i was worry a bit about not having enough pins…
Is there any special interaction on other pins. Cause i have try P8 and P9 as serial out and the speaker was making funny noise.
Maybe it was too fast “115200” aint try any other speed.
BTW: I am learning a lot doing this, with BasicAtom Manual, and BSP28 manual… !
Some devices require using the “inverted” mode when using TTL serial. Because the normal RS-232 chips invert the data.
I have them plugged on P0 P1 and it work fine. But on P8 and P9 the onboard buzzer is doing some funny noise…
No problem here i will keep P0 P1.
A new video:
Look in HD since even the HD is poor… 
(iPod touch… don’t have anything else to make video)
I can say that it’s realy easy to use…!!

The speaker can be disabled…
Yes i know…
But i found a way that it work… so i’ll stick with it. :mrgreen:
Ok i have a question:
In the Phoenix code… i want to slip in my uOLED file…
I want to know where i can start it…
Some of my code need to be done only once… !

Pretty cool display! It would be interesting to use on the DIY remote. What baud rates does it support?
