I had previously used the Adafruit TFT display using my library (ported from the Adafruit Arduino library). I decided to optimize the library to improve drawing speed. The same display I use comes with a 4-wire resistive touch-screen as well. I decided to write a simple library for the touch-screen and give Protothreads a try. To incorporate all this, I thought it would be cool if I used these to make a simple game. Tic-tac-toe came to mind as a fun little demo. I'm sure everyone's familiar with the game so I won't explain the rules there. The touch-screen is simply two resistive sheets placed on top of each other on top of the TFT screen. When it is pressed down at a given place, the two sheets make contact and a voltage divider is formed. Using the IO's and the ADC, this voltage is read in the X and Y directions to register a touch. Here is a very good pictorial depiction of the resistive touch screen (taken from the Atmel AVR341 document ): So in order to read the to...

  One of the most exciting news is when we know of 'futuristic' devices will probably inspire you to move forward in design and in different ways. It is something that Samsung intends to offer the Samsung Galaxy Note Edge . The Samsung Galaxy Note Edge is unlike any other phone we've seen in the market, but uses basically the same concept flexible display the company showed at CES 2012. The Galaxy Note has a QHD screen Edge (2K) 5.6 megapixel (2,560x 1,440), the same as the Samsung Galaxy Note 4 inches only smaller. No enmbargo on the right edge of the screen is folded and covers part of the right edge of the cell. This edge has a bar full of icons, widgets and useful information that can function apart from the front of the display or may display related to the application that is in the main part menus. The Curve Bar display can be rotated by swiping your finger across the edge to provide icons, shortcuts, S Health data, markers games, weather and more. You slide sideway...

Samsung announced its new phone Samsung Galaxy Note 4 focusing on providing better and no drastic changes. The Samsung Galaxy Note 4 features the same screen size as the Galaxy Note 3 (5.7 inches), but now integrates a QHD screen (2K), the same resolution offered by the LG G3 today. Additionally, the Galaxy Note 4 features a new metal frame that gives you much more elegance though other components are primarily made ​​of plastic. This reminds us a little Samsung Galaxy Alpha, the frame design is not exactly the same. He also is the first phone with Snapdragon processor 805 that bind outside the Asian market. The processor is 2.7GHz. Also find and 3GB RAM, 32GB of storage (with optional 64GB), microSD card support up to 128GB Android 4.4 and KitKat. Samsung has integrated fast battery charging battery in 30 minutes would allow about 50 percent of the battery that has a capacity of 3,220mAh. The cameras have also improved in many aspects. It's not just the fact that the rear camer...
