The 8051 microcontroller family has been well-known over many years. The development of new derivatives is not finished yet. From time to time new powerful derivatives are announced. You will find derivatives from Philips, Dallas, Analog Devices and Cygnal and others with the known 8051 core but enhanced clock and peripherals.  For example, complete analog-to-digital and digital-to-analog subsystems were integrated in some chips. Atmel developed the AVR microcontroller family which is well suited for high-level language programming and in-system programming. For all those microcontrollers there is development software ranging from simple assemblers for DOS to integrated development environments for Windows95/98/NT on the market. Apart from programming environments for professional applications, also the more economical and nonetheless sufficiently equipped development environments can maintain ground. BASCOM-8051 and BASCOM-AVR are development environments built around a powerful BASIC compiler which is suited for project handling and program development for the 8051 family and its derivatives as well as for the AVR microcontrollers from Atmel. The programming of microcontrollers using BASCOM-8051 and BASCOM-AVR will be described in this book. Some applications help understand the usage of BASCOM-8051 and BASCOM-AVR.

It is a great source of inspiration for those who want to automate their everyday work with robots. You can download the magazine from here.

CMPS-03 is an electronic compass built specifically for Robots navigation. It detects the earth's magnetic field to determine directions. It works on 5V, 15mA supply. Its output can be taken in two ways:

1) By a PWM Pulse:
In this method it outputs a pulse whose width varies from 1ms(0 degree) to
36.99ms(359.9 degree). One can connect it directly to a microcontroller and set the micrcontroller to measure the width of the pulse.

2) By I2C protocol
You can also get the output through I2C prtocol. You just have to connect its SDA and SCL pins with the respective pins of your controller and here you go.

N.B. If you are not using I2C then donot forget to pull high SDA and SCL pins of the compass to 5V.

You can get the complete documentation about this wonderful invention here.
