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:

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

It's 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 :)
