All of you must have played a very famous game know as Tetris. This review is about ‘myTetris’ which is a giant (~6ft tall) physical version of Tetris developed by National Instruments. It features a grid of 10×20 RGb leds along with myRio. For those who don’t know myRio is an embedded hardware device designed specifically to help students design real, complex engineering systems more quickly and affordably than ever before. It has a dual-core ARM® Cortex™-A9 real-time processing and Xilinx FPGA customizable I/O all in a single board.
The game can be played using any browser including those of mobile and tablets. The user taps the buttons on the web-page or use the arrow keys on the keyboard to move the tetrominoes. The web-page on your bowser also update your current score in real time. Also at the end of the game, it shows some statistics about the game performance and your final score. The LEDs are driven by a WS2801 chip using SPI which clocks in 24-bits on the data line (8 for each of red, green & blue) and then passes any subsequent bits to the next WS2801 chip in the strand. A really nice piece of Game from people at National Instruments.
