Displaying Videos and Images on 4Dsystems uOLED Serially

[rmteo]

Those parameters are correct for a 2GB card under Win7. Note that both displays use micro-SD cards - not SD.

Make sure you download the Graphics-Composer Software Tool: This is a free software tool for Windows. This software tool is an aid to composing a slide show of images/animations/movie-clips (multi-media objects) which can then be downloaded into the memory card that is supported by the GOLDELOX-GFX2. The multimedia objects can then be called within the user application 4DGL program.

This is a 4D issue and you should see if it can be resolved over at the 4D forums. I use a 4GB SDHC uSD card and it works for me under 64-bit Win7.

Sorry for getting out of the topic here. I think though that has to do with the configuration of the Oleds from 4d so it would be helpful for everyone.

What happend to me is, when i format it, it doesnt like to write the graphic composer on the uSD.

I took the uSD out of the computer port and then i placed it back. Windows asked me to format the card. I just pressed cancel.

Then i opened the program again and i tried to send a picture. It was ok then and it seems that the file sent to the card.

But i cannot see what is happening to the card since is not formatted.

I will try to buy an other uSD and i will also try a windows XP computer and let you all know.

thanks for your help.

Hi all again,

i download from the 4D systems the new graphic composer 3.

This is how it looks like.See attached picture (graphic comp3)

then we click on add on the left bottom and we import a picture. (see attached pic1)

then we click on save and we create the name of our fiel, then we click on built see attach, and we create a file cgs. After that a new window opens and we have some options.

I used the uSD_RAW FAT because i didnt know what else to use.

I havent received yet the 4D1,5 OLED but i'm trying to see how the uSD work.

after this configuration i cannot see the uSD file in windows, because it is as RAW FAT save.

If you use the tools from 4D that you can make partitions on the uSD then you will be able to use both RAW and normal windows fat system.

I cannot go further since i'm still waiting for the display.

When i get them i will keep you all updated.

The above configuration is for the SCG mode displays.

hello all again,

just came back from Saudi, and just got my precious small 1,5' oLED and the 1,44' uLCD.

Now i would like to play with them since is the first time i get this kind of component.

First of all i would like to talk again about the uSD and the files stored in there.

I have 2GB uSD and i have formated in format 16. Then i open the RMPET tool from 4D systems and i manage to use 50% for uSD RAW.

Then the program asked to remove the uSD and place back again. After this process windows asking to format again the 50% of the uSD.

I did that and now i can only see the 50% of the uSD.

My question is:

Do i need to store the pictures on the uSD before i send the to the uSD RAW partition space with the GRAPHIC COMPOSER.

To be more clear my question is, if i should manually first copy and paste the files in the visible 50% partition space, and then i open the graphic comsposer and via the program to send the pictures with uSD RAW.

By the way, i have plugged the uLCD via serial usb converter to my laptop and with the FAT controller i played a little bit with pictures and fonts.

very nice display.

Thanks for any help in advance.
