02/15/10 version 1.0 Assembly Instructions for 128x64 Graphics Display Unit This document describes the physical assembly of the Graphic Display unit for the 16 Bit Experimenter 128x64 Graphics kit. It was created by KibaCorp ( www.kibacorp.com ) to be used in conjunction with the 16 Bit Micro Experimenter on a solderless breadboard. The graphics display unit consists of a LCD backlight modules and total assembly should take under 15 minutes, however, special attention needs to be given to the removal of protective covers and films on both the LCD display and backlight and then their final assembly. A soldering iron will be required. Kits Contents The kits should contain the following: 1. (1) EADOGM128W-6 LCD Display package 2. (1) EALED55X46-W LCD Backlight package 3. (9) 1 uf ceramic capacitors ( marked 105) 4. (3) 100 ohm ¼ watt resistors 5. CD-ROM with Assembly Instructions, Code See attached figure (CD-ROM Not shown) Figure 1 Kit Contents
Graphics Module Assembly Remove the Backlight and LCD module from their perspective packages. Line them up side by side and you should get something like is shown in figure below. Both modules contain protective films that will need to be removed before final assembly. The final assembly will consist of the LCD display mounted on top of the Backlight module and then soldered together. Let s start with the Back Light module first. 1. Backlight -Step 1 Remove plastic cover from top of back light module. As shown. 2. Backlight Step 2 Remove the next layer of covering material from front of backlight it is marked with white tape around the edges.
What you should be left with it is a final covering for light dispersion with black tape on top and bottom. Leave this covering you are done with the back light for now. 3. LCD Step 1 Let s now work the LCD module. Let s remove the front cover plastic protective film as shown.
4. LCD Step 2 We are done with the front of the LCD, let flip it on it back as shown. 4. LCD Step 3 Remove the protective plastic cover from the back of the display as shown. Ok we are now done with the LCD display.
5. Final Assembly the of Graphics Kit You should now have the units completely remove of all protective covers and lined up side by side as shown Take the LCD unit and place it on top the backlight. The Pins of the LCD should align with the corresponding holes in the backlight. The assembly should now look like what shown here. We are not done. The units need to be soldered together. Before doing so make sure both units are flush with each other. This is important for two reasons 1. Maximum light transfer from backlight to LCD 2. Maximum extension of pins from bottom to enable plug-in to solderless breadboard as a complete unit. Turn the unit up side down, again make sure the two modules are flush,-- and Apply solder to bottom pins. Congratulations- your graphics Unit is complete!
6. Integration and test You now need to integrate with your 16 Bit Micro experimenter. First turn off the Experimenter, and then plug in the Graphics Module as shown. You need to supply a large format solderless breadboard and hook up wires. The kit supplied capacitors and resistors are used to complete the circuit. Complete the circuit using the hook up diagram. You will need to supply +3.3VDC and ground to the unit. Power is readily available from the 16 Bit Experimenter. Once done you can turn on the Experimenter. The graphics unit should be backlit. The Demo application code for this project is downloadable from the Nuts and Volts website www.nutsvolts.com or www.kibacorp.com and it also included in the kit CD- ROM. Make sure to install all Microchip tools ( MPLAB, P24F C Compiler, and PICKIT2) before hand. Please download, unzip, and place the project folder GRPAHICSDEMO on your desktop and put these in a convenient location on your computer. Now connect the PICKIT2 to USB of you computer and the other end to the ICSP on the Experimenter. Switch on power to the Experimenter. Open the folder containing our application code, and double click project file SDMMCTest.mcp. You should see the MPLAB GUI with the demo project directory visible, C code for Main function is open, and the output window should display PICKIT2 ready, PIC24FJ64GA002 found, and show that target power is applied. We are almost there. On the IDE toolbar click the Build button, and watch IDE and PIC 24 C Compiler compile the program. The output window should indicate no compile error. Use Program option pull down list and select program. The PICKIT2 will then actively program the PIC24F flash on your breadboard through ICSP. At the completion of this your Experimenter ought to automatically come up with Graphics Application. You can now either remove the PICKIT2 from the ICSP or leave it connected. The Experimenter will now work independently on each power up cycle. The demo should exercise the graphics unit with all the features of the KibaCorp graphics Library automatically enjoy! Figure 1 shows an example of the graphics kit in use with the Experimenter running the GRAPHICSDEMO software. Figure shows hook up of
