Topview Trainer for 8051 Microcontrollers

Topview Trainer was another interesting and useful study tool we developed for the 8031 /8051 microcontrollers. The hardware was designed to be the minimum with basic features to save on the cost. But, the software features were really outstanding with all the required debugging options. The internal details of the controller were presented in a most effective way to make the understanding on the program flow an easy and enjoyable experience. Because of the cost and the useful software debugging features, the Topview Trainer became popular with the educational institutions. Those days, debugging features were available only with high-priced trainers only.

We started selling these trainers with an attractive cost of only Rs3500/. As usual, it was promoted with Money-Back Guarantee.

We could sell a decent volume of these trainers and then it was slowly discontinued from our manufacturing.

If you are serious in doing anything on 8031, the Topview Debugger is the best thing made available to you.

Topview Debugger

Topview Debugger is the most important facility meant for developing 8031microcontroller based Embedded Solutions. Debugging is an inevitable part in any development environment to implement applications in real time. A right debugging tool should save a lot of development time.

Topview Debugger gives you unmatched power to manage 8031 based projects.

This debugger is a two part program in which the major part stays inside of the Topview trainer that keeps track of internal operation of the microcontrollers. During program execution, it catches information on various registers contents, internal/external memory areas and also various peripherals of the microcontrollers. This information is later transferred to the host computer to which it is connected.

Second part of the debugger operates in the host computer and is responsible for presenting the information received from the trainer in a most useful format using a GUI environment.

The debugger presents a GUI environment in which the clearview window structure gives facility for viewing/editing Program Memory, Internal Data Memory, information on various internal registers, SFR bits and etc.

When you use clearview windows you can visualize all the changes happening in the microcontroller’s internal architecture in a single screen. You can verify the internal, external memory spaces, various registers, SFR bits, along with the program code lines.

Another important feature of the debugger is the built-in program editing facility with the provision to run an external assembler for assembling the edited input program file.

You can compose your target program in this editor and send the edited code into the assembler and get the assembled code in a single shot.

There is an option to load the assembled code into the Trainer’s Program Memory at the predefined location.

All this happens in a single step for your convenience.

In the Program Memory window, the address, opcodes and mnemonics with SFR names are displayed line by line with distinct colours.

The Program Memory sports a single line assembler. So you can simply enter your program line by line using mnemonics.

The window also disassembles the hex input file and generates the actual assembly program.

You can also download a binary or hex file in the Program Memory of the Trainer reading from the disk.

Similarly, you can store the contents of the Program Memory into the disk either in hex or binary format.

In the internal Data Memory window, you can view/edit the memory contents. Facility is provided to Fill and Copy internal Data Memory contents.

External Data Memory window also supports all the above mentioned and also sports the facility to test the external Data Memory space.

In the Register and SFR window, the names of all register are clearly displayed to make you life easy during repeated debugging.

There are many ways in which you control the program execution to suit your needs. During every break, all the windows update their contents and indicate the changed values in a different colour to grab your attention.

You can execute the total program in a single shot and then check for the desired results.

You can also execute your program upto a Breakpoint and then verify the contents of various registers and the memory. The breakpoint can be defined using registers, internal Data Memory, SFR bits, External Data Memory.

There is another useful feature available to execute the subroutines in a single step. You need not execute a subroutine block line by line.

Having described the debugger in detail, we are sure that you understand the clear advantage you get when implementing your next embedded solution using Topview Debugger.

We once again remind you that a good debugging tool may save you from many hours of frustration. You can also finish the project before the anticipated time.

Our experience shows that at least you can save about 30% of the development time when using this powerful debugger.

Concept of Platinum Trainers.

We, at Frontline Electronics, are pleased to introduce an advanced learning platform for the world’s most popular microcontroller, 8051, using the state of art technologies. We call this working environment as the Next Generation Platinum Trainers. The Platinum trainers sport a variety of useful features to make experimental tasks an easy one and motivate the users to work more and learn faster in the given time.

Major facilities are the availability of a big size LCD Graphical Module that displays more useful information than ever before. The trainer interaction is made simplified by using standard PC keyboard.

In the stand-alone operating environment, the trainer supports the program entry in assembly language to save time apart from easy understanding of the programs. For the assembly programs, the trainer provides full-fledged debugger using the big size LCD display and the keyboard.

Combining the trainer with any personal computer, the trainer presents an advanced working environment for the high level C based program development. Apart from all these, the trainers come with built-in self-diagnostic features to test most of the functions of the trainer and the peripherals of the microcontroller.

As you know well, even so called advanced trainers of today come with a simple facility to download the assembled code generated in the computer using a cross assembler. They use the serial port for this communication. Even then, only very few trainers come with the debugging facilities for the assembly language. Most of the time, users develop the application code using the computer and download the same into trainer for experiments and projects. In many places, especially educational institutions, staff members cannot spare enough computers for the microcontroller development that in turn slows down the students’ learning to a great extent. In our experience, even premier technical institutions expressed their difficulty to provide the computer for every experimental setup.

Because of this feedback, we developed these Platinum trainers with all the required facilities built in the trainer itself.

Now, students can develop assembly programs easily using the big size LCD and the PC keyboard. They can also debug the programs in a professional way without any restrictions. The debugger is really a professional one without compromising on features.

The hardware construction of these Platinum trainers is radically different from the other available trainers in many ways. With regular trainers, the programs are downloaded into the trainer through the serial port. The communication link between the computer and the trainer is using a serial port.

As shown below, each of these Platinum trainers sport a System On Chip (SOC) built in-to the design to substitute the functions of the computer. The SOC acts as a front-end functional facilitator for the microcontroller. This SOC is responsible for user interaction and for the program development.

As you can observe, this SOC and the microcontroller communicate with each other using a parallel communicating port whenever it is required. Apart from this communication, the SOC does not interfere with the operations of the microcontroller. There is an indirect benefit available out of this: The available serial port of the microcontroller is left free for your applications.

In short, this SOC handles the assembly program development, program debugging, local program storage, retrieval, and self-diagnostic operations. Under C development environment, the SOC interacts with the computer and manages the communication link between the computer and the microcontroller without any interference.
