This week, we’re diving into function block Math operations. IoT sensors, controllers or cloud data processing often needs to do some numerical work to make them smart. Lucid makes these operations incredibly straightforward. The most general maths function block allows algebraic expressions to be entered, or you can choose from individual operator function blocks, but let’s start with some simple algebra! Single input single output or multivariate blocks are available, but here we are using a single input value doing…

It’s week 3 of FBF and we’re looking at User Interfaces for devices. Graphical UIs in Lucid are built from inxware’s widget library that perform well-known user interactions such as displaying and acquiring text or numerical data from users. More advanced widgets include images, shaped objects, video, graphs, animation and even sound. To get started the Hello World application below shows a simple interactive text box app in the Lucid IDE and inxware enabled device simulation in the window below.…
