Introduction: Gameboy Using MSP430

this is a gameboy developed by me, using msp430g2553, and 2 shift registers, 74595... it includes 8x8 led matrix, which is build on the board....
watch the video at....

Step 1: Material Needed

for this you will need...
1] dotted pcb
2] 70 led [coloured]
3] MSP430G2553
4] 2x 74595 shift register
5] 2x DPDT switch
6] 4x micro switch
7] ic bases
8] potientiometer 4k7
9] decoupling capacitors [104]
10] on\off switch
11] 8x BC547
12] 8x 1k res.
13] 5x 10k res.
14] 4v battery
15] ti launchpad
16] ti Code Composer Studio

Step 2: Layout

then you have to select the positioning of your 8x8 led matrix and all other components according to your PCB...

Step 3: Building the 8x8 Med Matrix

you can get instructions how to build an LED matrix on many pages on the internet, here is the process, by which i made it....

Step 4: Making Connections

its the hardest part of building the hardware, and you must be careful about making the exact same connections as i made, otherwise the code wont work on it, i have uploaded an eagle's schematic file, with the diagram which shows the essential connections which are to be made EXACTLY the same way...

some important connections of IC 74595

pin10-vcc-10k

pin9-cascade data, pin 14 74595 or open if its the last IC in cascade

pin11-shift clock-pin7 msp

pin12-latch clock -pin 6 msp

pin13 - gnd-10k

pin14 - data - msp15 or 74595-pin9

pin15- data bit 0

Step 5: Burn the Code

burn the code into MSP430G2553 by ti's launchpad....
here is its photo getting coded....i have attached the main file with it...

Step 6: Enjoy the Show :)

just keep on playing untill you have a new idea to built something else ;) or maybe just a new game for this gameboy :)

hi again,can you tell me what value that liquid dielectric capacitor you used :)

Can u tell me something more about decoupling capacitor....why have u used it and its value??

you can use any thing between 200uF and 1000uF; and volts can be in between 10v-30v

Also From the schematic diagram, I could not understand the connections of DPDT switch and decoupling capacitor.

sorry to reply late.feel free to ask any questions...

This capacitor is used to filter any disturbances of voltage across the switches, to have clean 0/1 (0volt/5volt) values.

Hi again,sorry about so many q.but i have one more,you use 104 capacitors in your device,but on schematic i cant find this capacitors,can you tell me where should i put them in this schematic,i need it for my diplom project

Can you tell me in what program the schematic is draw?

the software is EAGLE 6.2.0.

Hi can you tell me what pcb do you used? how much cm hight and long?
