-Since, it is very inefficient to light up all the 4096 leds at the same time, The images/frames are shown on the display through a process called scanning where only a few rows expressed by its scan rate are driven at the same time. For the scan rate of 1:32 in a 64x64 led matrix, each row from the top half and the bottom half are displayed serially.

For the scan rate of 1:32 in a 64x64 led matrix, each row from the top half and the bottom half are displayed serially, more details can be found in the article from sparkfun in the reference section below.
 For each row of pixels, we repeat the following cycle of steps:

−	In this project we remastered the arcade music game Jubeat in a tight budget. We used a 64x64 LED matrix to display the animation, 12 capsense buttons to detect the finger touch inputs, and a mp3 module ~~that~~ connected to the speakers to play the songs. Drivers for the LED matrix display, the capsense, and the mp3 module were developed for this project.	+	In this project we remastered the arcade music game Jubeat in a tight budget.

-Jubeat is a music game uses an arrangement of a 3x4 grid for the game play. An animation pops up on each grid according to the beat of the song. The player has to use his fingers to tap on the screen and catch the animation in time. The scoreboard locates on the top row of the LED display. Different scores will be given depending on when the player catch the animation. Tapes can be judged as PERFECT, OK, and MISS.
