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....

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Material Needed
for this you will need...
1] dotted pcb
2] 70 led [coloured]
4] 2x 74595 shift register
5] 2x DPDT switch
6] 4x micro switch
7] ic bases
8] potientiometer 4k7
9] decoupling capacitors 
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
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 :)
