Overview
Introduisez la connectivité clavier et souris sur l'appareil avec cette solution économique : le PS/2 Click Board™ .
Cette carte d'extension comprend un connecteur PS/2 Mini-DIN 6 broches standard, un brochage MikroBUS et un voyant d'alimentation . La PS/2 Click Board™ dispose d'un port PS/2 pour connecter un clavier ou une souris au périphérique cible. Bien que remplacé par l'USB, il est toujours utilisé comme alternative au connecteur USB. Il est bien adapté pour connecter des claviers et des souris vintage ou certains claviers haut de gamme pour les joueurs en raison de sa fonctionnalité complète de basculement N-key.
La carte PS/2 Click Board™ communique avec votre carte cible via les broches MikroBUS RST (données) et CS (horloge). Elle est conçue pour utiliser uniquement une alimentation 5 V.
The PS/2 Click Board™ is a cost-effective solution for adding keyboard and mouse connectivity to your design. It features a standard 6-pin Mini-DIN PS/2 connector, a mikroBUS™ host socket, and a power indicator LED. PS/2 click communicates with the target board through mikroBUS™ RST (data) and CS (clock) pins. It's designed to use a 5V power supply only.
PS/2 Connector
The PS/2 Click Board™ has a PS/2-style 6 pin mini-DIN connector used for connecting some keyboards and mice to a PC compatible computer system. It was irst introduced by IBM way back in 1987. It works on a serial, synchronous and bidirectional communication protocol.
Full N-Key Rollover
The PS/2 Click Board™ is used in certain high-end keyboards, especially for gamer keyboards as it supports n-key rollover. This means that each key is scanned entirely independently by the keyboard hardware, and thus, allowing the high-end keyboards to handle any number of simultaneous keystrokes.
Why PS/2 over USB
Though superseded by USB, PS/2 connectors are still used. The PS/2 connected keyboards are faster, and have slightly shorter effective scan intervals than their USB counterparts. PS/2 supports full n-key rollover, whereas USB keyboards can handle typically two to six keys at a time.
