The 4 step guide to program your P89v51RD2 controller using TRI ISP
Step 1: Port Settings
Port Number: Select the serial communication port of your PC to which the target device is connected. Most present day IBM compatible PCs have a single serial communication port with an address of COM1.

Speed: Select the burning speed. (Preferably 9600)

Step 2: [...]

TRI has come up with source code development environment “TRIC” which has everything you need for rapid program development . TRIC helps expedite the development process of your embedded applications by providing the following features:

1.Windows-based IDE that combines a robust editor, project manager, and compiler.
2.TRI C integrates all tools including the SDCC compiler(which includes macro [...]

What are micro controllers?
A highly integrated microprocessor designed specifically for use in embedded systems
A microcontroller is a computer-on-a-chip optimised to control devices.

These are some of the definitions of a microcontroller or �C as we would refer to it from now on. We can conclude safely from the definitions above that a �C can [...]

In this section I will be taking you to the world of SPI and we will see how to interface it with a memory device.Let us first understand what a serial communication is all about.
Serial buses occupy a significant place in embedded design.From [...]

Edge Avoider Robot is built using the IR based Line Detecting Module. The modules are connected in front of the iBOT so as to detect the edge early and take proper action in time. The distance between the sensors is also maintained greater that the width of the iBOT considering the turning radius of [...]

In this article we will learn how to Create Projects, Edit Source Files & Compile using TRIC…
STEP 1
To create a new project file select New Project from the Project Menu. This opens a standard Windows dialog box asking for project file name. Generally its a good idea to save different projects in different folders. [...]

Accelerometer is a device which is used for measuring the acceleration and the tilt angle of any body over which it is mounted. The output of an Accelerometer IC is in terms of variable voltage linear to the acceleration or the tilt angle. So accelerometers can used in lot of applications as two wheel balancing [...]

Wall Follower using iBOT or 8051 is built using TSOP based infrared sensor
module. The Right module is used to detect the wall on the right of the iBOT.
Wall follower application can be built with only one module, but we are using
the other sensor to avoid obstacle in front of the robot. The Right module is
connected [...]
