I have to start by saying that those guys at 4Dsystems really know what they are doing. they have made it very easy to display video, images, and even animated gifs on their Displays.

- For my setup ill be using the µOLED-128-G1(SGC)
Note: the (SGC) indicates that this is a serial display and has the 4Dsystems Pmmc firmware loaded.
- My Controller board consists of a PIC16F877A , 5 Button dedicated RF interface (Key Fob), including Ports B,C,E brought out to the board edge.
- Also in this setup is the Parallax RFID reader (serial). Radio shack has these on sale for $5. i have a few

Ok. Lets start with Graphics Composer. Once you download your free copy of Graphics Composer Software, you must read the Graphics Composer manual. Unfortunately there are no links to the manual it is zipped with the software. It fully details how to get images onto your Micro SD card (uSD). There are 2 ways to get your images/videos to your uSD card. plugged directly into you computer as a Drive (recommended). or serially through the Display (which is very very slow).

I chose to plug it into my computer. Very important to NOT "Quick Format" as it needs to write to the boot sector. when you get all your files loaded via the Device>Load it will give you a TXT icon that you can click on. This TXT file (Below) is the most important part. it basically just hands you the code that you just need to copy and paste into Pic Basic (Pro).

Code:
===========================
SERIAL-PLATFORM OUTPUT FILE
===========================

---------------------------------------------------------------------------------------
File "Danger_Laser_Operating.gif"
Sector Address 0x001000
Width = 128 Height = 128 Bits = 16 (Location and size may be adjusted depending on image size
                                     and Size Mode selected)

Display Image from Memory Card (Serial Command):
Syntax:
@, I, x, y, width, height, colourMode, SectorAdd(hi), SectorAdd(mid), SectorAdd(lo)
Data:
0x40, 0x49, 0x00, 0x12, 0x7F, 0x5B, 0x10, 0x00, 0x10, 0x00
You will need to change all the "0x" to "$" in order for PBP recognize the values. This example only shows one file. the text file would grow depending on how many items you put on your micro SD Card.

below is an example of PBP Code with the Data given from the TXT File above. This Code basically Turns on a laser and tells the display to show the file "Danger_Laser_Operating.gif" at Sector Address 0x001000.

Code:
DEFINE OSC 20
