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 ...
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 ...
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 ...
In life and embedded systems timing is everything. Give [Frank’s] web-based timer calculator a try. Set your system clock resolution (in hertz making sure you account for any system clock divider), ...
Most digital timers require a set of dip switches or rotary BCD encoders to preset their interval. But those techniques consume eight or more inputs from a microcontroller's (MCU's) I/O lines. To ...
After the electromechanical timer on [Paul Canello’s] washing machine broke for the third time he decided he needed to stop repairing it and find a more permanent fix. He decided to build his own ...
Embedded World — Nuremburg, Germany -- February 23, 2015 -- A new 16-bit 80251 microcontroller IP core shipping now from CAST, Inc. runs 69.7 times faster than the original 8051 chip, making it the ...
