# panelui(1)

interface buttons to LinuxCNC or HAL

## NAME

panelui - interface buttons to LinuxCNC or HAL

## SYNOPSIS

**panelui**

## DESCRIPTION

**panelui** is a non-realtime component to interface buttons to LinuxCNC or HAL. It decodes MESA 7I73 style key-scan codes and calls the appropriate routine. It gets input from a realtime component - sampler. Sampler gets it's input from either the MESA 7i73 or sim\_matrix\_kb component. Panelui is configurable using an INI style text file to define button types, HAL pin types, and/or commands.
