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 ...

This section deals with the study and use of timers and counters of pic18 series.Timers are generally used to create very accurate time delays and counters are primarily used to count any number of ...

An accurate way to calibrate a frequency source is to use a high-resolution counter/timer to measure the beat frequency, or phase difference, between the source to be calibrated and a reference such ...

Two multifunction I/O modules feature both digital I/O and counter/timer functions on a single PMC module. The PMC424 provides 40 digital I/O channels for transistor-transistor logic (TTL) and ...

The module’s operation consists of reading data of a 24-bit timer/counter and transferring it to three registers called TMR, CPR, and PR. The SMT can perform a variety of measurements such as Gated ...

For those embedded systems that can’t be constantly watched by a human, watchdog timers may be the solution. Most embedded systems need to be self-reliant. It’s not usually possible to wait for ...

Self-contained machines such as fryers for fast-food restaurants, cook-and-hold ovens, and bakery equipment usually employ a simple automatic controller. A typical controller includes one or more ...
