All About Samsung's Low Cost REX series smartphones

Samsung has made the phones in all range and for all types of people. It seems that Samsung Electronics wants to take on all its rivals in every segment. So, Samsung is taking on Nokia Asha series low cost smartphones ranging from 42,00 to 65,00 Indian rupees, has launched the 4 different REX series smartphone with different functionality and features:

Samsung Rex 60 is a dual-SIM phone with 2.8-inch resistive touchscreen with 240x320 resolution and comes with 10 free games from Gameloft. The company has included a 1.3MP rear camera in the phone, which is powered by a 1,000mAh battery. Other features of the device are Bluetooth 3.0, microUSB 2.0 and microSD support up to 16GB.

Samsung Rex 70 has a 3-inch touchscreen and can handle two sim cards simultaneously. This phone sports a 3.2MP camera on the back and has connectivity features like Bluetooth 3.0 and microUSB 2.0. Battery capacity of the phone is 1,000mAh and it can support microSD card with capacity up to 16GB.

Samsung Rex 80 also features dual-SIM capability, 3-inch touchscreen, 3MP camera and 10 free games from Gameloft. Powered by a 1,000mAh battery, this phone has connectivity features like 2G, Wi-Fi and Bluetooth.

Samsung Rex 90 has a 3.5-inch touch-enabled display and features a 3.2MP camera on the back. Connectivity features of the device include Bluetooth 3.0, 2G and microUSB 2.0. Powered by a 1,000mAh battery, the phone has supports 32GB microSD cards as well as dual-SIM. It comes loaded with applications like Chat On, Twitter, Google+, Facebook and a few more.




Verdict:

All four REX series phones are built on TouchWiz Lite UI operating systems and comes with preloaded apps for the user. These phones only vary in terms of their size ranging from 2.8 inch to 3.5 inch and display in which only REX 90 has 320x480 pixels resolution whereas other have 240x320 resolution screen with different megapixel camera configuration.

They also seems to be slightly different in terms of internal storage- Rex 90 comes with 10 MB that can be expanded to 32 GB with microSD but, other can be expanded to 16GB only and comes with 20 MB in Rex 80, 10 MB in Rex 70 and 30 MB in Rex 60.

Buzzer interface with 8051 microcontroller

Buzzer  is a electronic device that converts the electronic signal into buzzing noise, that is applied to it. It can be used as electronic bell or as quiz buzzer in many applications around us. Here, i world like to discuss the interfacing of a small buzzer with 8051 microcontroller and how different projects can be constructed. Buzzer Interfacing: This project shows the interface with AT89S52 microcontroller to a buzzer. When a push button is pressed, the buzzer will get ON and OFF ( number of times set in the code ) and then stops. Circuit Diagram: - The port P1 of the microcontroller is connected to buzzer. This type of connection is possible, if the current requirements of the buzzer is not more than 20mA. The output is in current source mode so that buzzer will turn ON when the output of the port is logic LOW. Switch is connected to port P3 which remains at logic HIGH by pull up resistor.  Code: #include "REG52.h" #define buz P1 sbit SW=P3^0; long i...

Comparison Chart Between 8051, 8052, 8031and 8751

8051 is a popular 8-bit microcontroller and has been used in many applications since Intel introduced it. Many 8051 architecture are produced by Triscend, Intel, Atmel, Philips, Infineon (Siemens), ISSI, and Max Corp. Today, 8051 microcontrollers may not be popular but, the 8051 architecture is still popular and employed in thousands of embedded applications. This 8-bit architecture has been different segments such as 8052, 8051, 8751 and 8031 . 8052 is the super-set of 8051 and 8031 is the memory-less microcontroller hence, it has interfaced with external ROM. Whereas, 8751 chip has only 4Kbytes of on chip UV-EPROM. Everyone knows about the general 40-pin microcontroller i.e. 8051 introduced by Intel in 1980s and consists of serial communication pins, Timer, Interrupts, RAM, ROM. It has 4 ports and each port has 8 pins, total 32 pins and other 8 pins for other purposes. 8052 is the super-set of 8051 that consists of 8K bytes of internal RAM (4K in 8051), 256 by...

Different ways to generate delays in 8051

The delay length in 8051 microcontroller depends on three factors: The crystal frequency the number of clock per machine the C compiler. The original 8051 used 1/12 of the crystal oscillator frequency as one machine cycle. In other words, each machine cycle is equal to 12 clocks period of the crystal frequency connected to X1-X2 pins of 8051. To speed up the 8051, many recent versions of the 8051 have reduced the number of clocks per machine cycle from 12 to four, or even one. The frequency for the timer is always 1/12th the frequency of the crystal attached to the 8051, regardless of the 8051 version. In other words, AT89C51, DS5000, and DS89C4x0 the duration of the time to execute an instruction varies, but they all use 1/12th of the crystal's oscillator frequency for the clock source. 8051 has two different ways to generate time delay using C programming, regardless of 8051 version. The first method is simply using Loop   program function in which Delay() funct...
