In-Circuit Emulator in Embedded Systems

In-circuit Emulators are the hardware devices that help in debugging embedded code in microcontroller. They are not only specified for debugging software but also, debugging certain parts of hardware. In-circuit Emulators are also called I.C.E devices that allow engineers , debuggers to emulate the microprocessors or microcontrollers. The in-circuit emulator take the place of processor and allow special control of the microprocessor such as stopping the device under test and checking/setting registers or memory, even showing a trace of the microprocessor has been doing real time before it was stopped.

There are different types and sizes of in-circuit emulators are available according to the need of engineers and it depends on their project requirements. The best in-circuit emulator can emulate a large number of processor family simply by changing the pod and reconfiguration of emulator. Microcontrollers or Microprocessors family are included such as Intel, Motorola, PIC, Samsung, NXP, ARM and many more.

Benefits- In-circuit emulator offers additional benefits when integrated with compilers. When in-circuit emulators are integrated with compilers, the build/make process is streamline so when bugs are found the code can be quickly changed in-circuit emulator environment and retested. You can get in-circuit emulators that can support multiple microprocessors built by different manufacturers.

Features- One of the greatest feature of in-circuit emulator is the ability to set trace condition. Complex trace condition and filters allow developers to trap bug and then look back the events that led up to the error. The trace offers the engineers a view of what he would normally not be able to see. The trace happens in real time which help of events that may need to happen without delays of stopping or even slowing down the microprocessors.

So, you can choose a good in-circuit emulator that comes in your budget and according to the compatibility of your computer or laptop as some configuration has to be checked before buying and using emulators.

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...

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...

How to Switch OFF Citizen Calculator

You might be confused on seeing no OFF button on your calculator. Actually, these are general calculator available at low cost in the market. They process simple calculations like division, subtraction, Addition, Multiplication. But, how will you OFF that calculator having no option on them. There is always a trick which OFF them. It depends on the company calculator and their series to which they belong. I can tell you about Citizen Calculator CT-500 (as you can see in the image), how can you switch OFF it and can save battery too. If you leave calculator idle for 6-7 minutes, it will goes OFF automatically. My calculator goes OFF in 6.50 minutes from the point of leaving it idle. But, this is not the power saving trick for these types of calculator having not much backup battery. To save the power of your normal calculator, here is the trick to switch OFF it. Press ' /(divide sign)', 'x(multiply sign)', '%(percentage sign)', 'autoreplay option(...
