MINIKLAWIATURA WITH PS / 2 INTERFACE - PLATE AND PROGRAMMED LAYOUT
Producer: AVT

A standard computer keyboard has more than 100 keys, which forces it to be placed in a housing with quite large dimensions. However, this type of keyboard is not always needed. In some cases, when a computer performs specific tasks, it requires only a few keys to operate it. The control takes place then from a small space-saving keyboard.
The Atiny system was used in the system. He is responsible for the operation of a simple, 16-key keyboard and his software includes procedures for eliminating contact vibration and assigning a button to a specific key from the "large" PC keyboard.

The device is especially recommended for designers of microprocessor systems cooperating with a PC computer and all PC users
