This tool offers a no-cost and user-friendly solution for computing the resistors required for creating a keyboard or resistor network on an A/D input.
The 1 Wire Keyboard Calculator (1-Wire Keyboard) is an incredibly useful tool designed specifically for embedded system designers. Its primary purpose is to allow these designers to implement a keyboard or keypad using just a single analog to digital converter (A/D) input. This makes it an incredibly efficient tool for those who may be pressed for time or resources.
For larger keypads or keyboards that require chording - meaning more than one key can be pressed at a time - multiple A/D inputs can be used, each with a portion of the complete keypad. The 1-Wire Keyboard supports from two (2) to 64 key keyboards, although anything beyond 26 keys may be challenging to achieve.
One of the key benefits of using the 1-Wire Keyboard is that it offers lower electromagnetic interference (EMI) than scanned keyboards. Additionally, implementing the keyboard requires fewer Electrostatic Discharge (ESD) protection components, making it an even more streamlined option for embedded system designers. Finally, the 1-Wire Keyboard requires just one pin on a microcontroller, easing the implementation of this tool for those with limited resources.
