1 Hal User Interface

1.1 Introduction

Halui is a HAL based user interface for EMC, it connects HAL pins to NML commands. Most of the functionality (buttons, indicators etc.) that is provided by a traditional GUI (mini, Axis, etc.), is provided by HAL pins in Halui.

The easiest way to add halui is to add the following to the [HAL] section of the ini file.

HALUI = halui

An alternate way to invoke it (especially when using a stepconf generated config file) is to include the following in your custom.hal file. Make sure you use the actual path to your ini file.

loadusr halui -ini /path/to/inifile.ini

in your custom.hal file.
