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.

Topview Debugger is extremely popular among our customers. It is the proven tool appreciated by our industrial customers who demand only the best. Our customers use Topview Debugger for many years. No one ever regretted for purchasing the tool.

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.

Topview Device Programmer

Even though we had many products before this one, only after launching this, we became known to the embedded system community of India. We gave a good programming tool with an attractive and unmatched cost. The launch price was Rs 2002, the figure matching the year we started selling this. At that time, even programmers costing many times more didn’t come with similar features. To give buyers confidence, we started selling these programmers with a 15 days Money back-Guarantee, which was a new idea at that time. We also kept all details on line for the users’ evaluation. The combination of all these things made this device programmer very popular with the users and it became an instant hit for us.

Even after selling few thousands of this programmer, we never had any customer returning this programmer to get his/her money back.

We still come across customers who talk fondly about this programmer and there are good number of customers who started their career using this programmer.
