Microcontroller software typically consists of a few hundred lines of code only, but it is rather different from standard application code. The software is highly hardware and platform specific, and bugs are often a consequence of neglecting subtle specifications of the microcontroller architecture. Currently, there are hardly any tools for analyzing such software automatically. In this paper, ...

Abstract This paper proposed the microcontroller based vector impedance meter, which can be used to measure unidentified impedance of the system. The microcontroller read only four samples from two voltage signals, the first voltage is proportional to the voltage across the impedance while the second voltage is proportional to the current passing through it. A novel algorithm is then used to ge...

In traditional Embedded Control Technology courses, students learn to develop assembly language programs to control peripherals, handle interrupts, and perform I/O operations. However, students find the subject are diffcult as the subject is presented in a lecture format. Unfortunetly, this Embedded Controller Technology (ECT) course is a compulsory course in any electrical or electronic field ...

In this paper, a digital clock is designed where the microcontroller is used for timing controller and the font of the Bangla digits are designed, and programmed within the microcontroller. The design is cost effective, simple and easy for maintenance.

This paper presents the design of crack finding robot for finding cracks in railway tracks. Here PIC16F877A microcontroller is interfaced with Robot, Zigbee, GPS, LCD and IR sensors. The IR sensors are used to find crack in the railway track, and then GPS is used to find the location. If the microcontroller detects the crack, it immediately gets the location information using GPS and sends that...

In this paper the hardware implementation of intelligent Tic-Tac toy is presented. The implementation uses Graphical LCD (GLCD) touch screen and microcontroller. The microcontroller receives the player move from GLCD (displayed as X) and uses intelligent algorithm to analyze the move and choose the best counter move. The microcontroller displays the counter move on the screen as circle (O). The...

The PIC16C781 and PIC16C782 are the first devices in a new line of mixed analog/digital microcontrollers from Microchip. These microcontrollers are a marriage of our traditional microcontroller architecture with new mixed signal peripherals that change many of the old conventions of embedded microcontroller design. Not only do the new peripherals open up new applications for the microcontroller...

There’s a broad field of applications for the microcontroller technology, that can be enumerated from simple, like small electric equipment operation, until sophisticated, like single loop digital controllers with man-machine and machine-machine interface, also using complex digital control techniques. The main preoccupation for us is to transmit to an undergraduate student, who hadn’t had any ...
