Displaying Videos and Images on 4Dsystems uOLED Serially

Is RX needed? That is why I pointed you to the reference manual for both displays.

You can get by without using RX but I would highly recommend that you use it. Take a look at post #12 - you will see that the display returns an ACK if the command is successful, NAK if unsuccessful. This can make your application run more effectively.

rmteo, thanks once more for your help.

That's why i ask you, now i see the response from the RX.

I have some SD cards here, and i would like to format them in windows 7 64bit.

I read some forum and manuals but i didnt see the format of erasing the microsd.

I did the following configuration.

Capacity : 1,83Gb
file system: FAT (default)
Alocation unit size: default
Format option: -

the only thing i found is the following migh also be interesting for you.

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.

i will post the problem in a bit.

I did format the usd. Then i opened the graphic composer tool.

and i did the following configuration.

on the device load option --> serial command platform and the drive is the letter G of the sd

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.
