The main intention of this circuit is to build a system wherein the number of persons entering or leaving a room has to be displayed on a screen. This is one of the best and very useful circuits in ...

Counter/timer hardware is a crucial component of most embedded systems. In some cases a timer is needed to measure elapsed time; in others we want to count or time some external events. Here's a ...

The 8051 is alive and well. Cygnal Integrated Products has crammed a 25-MHz 8051 core, 8 kbytes of flash, and 256 bytes of data RAM into a tiny 11-pin, 3- by 3-mm (9 mm2) micro-lead package (MLP).

In this paper the authors give a novel idea about the design and implementation of a microcontroller based pulse counter. Intel 8051 is used as the main microcontroller unit and the system has been ...

The major component of this circuit is Microchip’s SST89E54RDA-40-C-PIE, which is a pin-for-pin compatible with typical 8051 microcontroller devices. It has a built-in timer used to produce accurate ...

This paper describes the design and implementation of a version of the 8051 microcontroller, one of the most commercially used microcontrollers in FPGA with reconfigurable instruction set.
