Creating Project in Keil Micro Vision

-
Keil MicroVision is a free software, we use it for embedded program developing. In this software we have provided a platform to write a program using text editor, compile program to convert source code into machine language i.e. compiler will convert source code into hex file.  
Here is simple guidance for 
  • How to write programs in  Assembly language or C/C++
  • How to Compile and Assembling Programs
  • How to Debug program
  • Creating Hex and Axf file
  • Test a program without Available real Hardware (Simulator Mode) 
Here a program to write a data 55H to port 1  and complementing data after some time delay is explained. Following is the  process of  writing  program in Keil ,its  execution and Debugging :
    Step 1: Open Keil uV3



    Step 2: After opening Keil uV3, Go to Project tab,create New Project ,select new folder and  give name to the Project.

      
    Step 3: After Creating project following window will pop-up. Now Select your device model e.g AT89C51


    Step 4: To select device click on  left '+' sign in front of  Atmel device.

    Step 5:  Following window will pop-up. Now scroll down and Select your device model e.g AT89C51

    Step 6:  Following window will pop-up. click on No.

    style="text-decoration: underline;">Step 7: Now go to File and create new file, following window will open, this is text editor  to write your own code. Write the code in editor and save the it.

    Step 8: Save the program using extension '.asm' for assembly language or '.c' for c language.



    Step 9: Now Right click on Source Group1 and then add files to Group 'Source Group1'

     


    Step 10: Now Build the Target (compile the program) by clicking on build tab shown by green circle as below: It will give result of compilation in command window shown by red colored  square window :


    Step 11: Now  we can start Debug session using Debug tab  after that run the the program using Run tab shown by pink colored circle and check status on peripheral using peripheral tab.We can also check value of  general purpose register in project work space under the Register tab


    Step 12: If you want to watch waveform on particular port pin or port use Logic analyzer Window and add particular pin or port to the window then  you will see waveform on that particular port or port pin as shown below : here waveform on pin port 1.1 shown.

    Using the SG3525 PWM Controller - Explanation and Example: Circuit Diagram / Schematic of Push-Pull Converter

    -
    Image
    PWM is used in all sorts of power control and converter circuits. Some common examples include motor control, DC-DC converters, DC-AC inverters and lamp dimmers. There are numerous PWM controllers available that make the use and application of PWM quite easy. One of the most popular of such controllers is the versatile and ubiquitous SG3525 produced by multiple manufacturers – ST Microelectronics, Fairchild Semiconductors, On Semiconductors, to name a few. SG3525 is used extensively in DC-DC converters, DC-AC inverters, home UPS systems, solar inverters, power supplies, battery chargers and numerous other applications. With proper understanding, you can soon start using SG3525 yourself in such applications or any other application really that demands PWM control. Before going on to the description and application, let’s first take a look at the block diagram and the pin layout. Pins 1 (Inverting Input) and 2 (Non Inverting Input) are the inputs to the on-board error amplifier. If you a...

    Using the TLP250 Isolated MOSFET Driver - Explanation and Example Circuits

    -
    Image
    I’ve already shown how to drive an N-channel MOSFET (or even an IGBT) in both high-side and low-side configurations in a multitude of ways. I’ve also explained the principles of driving the MOSFETs in these configurations. The dedicated drivers I’ve shown so far are the TC427 and IR2110. Some people have requested me to write up on MOSFET drive using the very popular TLP250. And I’ll explain that here. The TLP250, like any driver, has an input stage, an output stage and a power supply connection. What’s special about the TLP250 is that the TLP250 is an optically isolated driver, meaning that the input and output are “optically isolated”. The isolation is optical – the input stage is an LED and the receiving output stage is light sensitive (think “photodetector”). Before delving any further, let’s look at the pin configuration and the truth table. Fig. 1 - TLP250 Pin Configuration Fig. 2 - TLP250 Truth Table Fig. 1 clearly shows the input LED side and the receiving photodetector as well...

    Using the high-low side driver IR2110 - explanation and plenty of example circuits

    -
    Image
    In many situations, we need to use MOSFETs configured as high-side switches. Many a times we need to use MOSFETs configured as high-side and low-side switches. Such as in bridge circuits. In half-bridge circuits, we have 1 high-side MOSFET and 1 low-side MOSFET. In full-bridge circuits we have 2 high-side MOSFETs and 2 low-side MOSFETs. In such situations, there is a need to use high-side drive circuitry alongside low-side drive circuitry. The most common way of driving MOSFETs in such cases is to use high-low side MOSFET drivers. Undoubtedly, the most popular such driver chip is the IR2110. And in this article/tutorial, I will talk about the IR2110. You can download the IR2110 datasheet from the IR website. Here's the download link: www.irf.com/product-info/datasheets/data/ir2110.pdf First let’s take a look at the block diagram and the pin assignments and pin definitions (also called lead assignments and lead definitions): Fig. 1 - IR2110 block diagram (click on image to enlarge)...
