AN2374: Wide Dynamic Range Programmable PSoC Counter Timer

Pulse counting is an essential application requirement in industry and R&D laboratories. Counting applications count pulses for a preset time period. Counter and timer units are crucial components of most embedded systems and are included in many microcontrollers as one or two counters or timers. In traditional microcontrollers, the built-in modular functions such as counters, timers, ADCs, and DACs are fixed components, but all are programmable. In a PSoC device, the placement of the user module functions is a design choice that you can change and reconfigure; not frozen hardware configurations like a microcontroller. This Application Note details a PSoC DesignerTM project that provides pulse counts for periods of a few milliseconds to several minutes. With the addition of a timer interrupt, it can go up to several hours. It uses a virtual instrument program so that you can control the program and display it on a personal computer
