Displaying Videos and Images on 4Dsystems uOLED Serially

[astanapane]

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.

Hi i'm stack in a bit on the connections and programming my microcontroller.

as from the schematic of 4D systems the display must be connected with the 5V,GND,RX,TX,RESET.

I will not use the TX from the oLED to RX to microcontroller, but do i need the RESET also? on your programs did you use the reset pin and connected to microcontroller?

i manage to fix it.

it is very easy.

My problem is some commands i cannot make it work.

i try to right a string serialy like the following but i cant.

I know somewhere i make a mistake could you help please?

serout2 portb.2,84,[$53,$00,$00,$01,$00,$00,"Hello",$00]

I think that there is somewhere a big mistake.

Regards

I fixed it with the command start with $73 for string TEXT. It is very easy to do.

thanks!!!

Satisfied with the LCD in general?

Hi Ioannis,

i manage to display pictures and text.

i used the SCG mode becase i found it easier to control.

To be honest 4d systems save me from a microcontroller such as the PIC18F4550.

Now i use the pic16f88.

i will post my code here the folloing days.

regards

as from the display,

it is small but very nice. You can use it in small projects and text is visible.

For my project i need the 3,2 inch display. I know it is expensive but i have to use the touch also.

you can see here my video.



i will post the code later on. It is based on the code you provided with a small changes.

I have one of the 3.2 inch displays that I no longer need. Let me know if you are interested.
