UNICA 1-Wire sensor module example

This folder contains the source files for demo project on using UNICA 1-Wire sensor module "U1WTVS". This module measures temperature, relative humidity and light intensity.

Timing of the project

The algorithm runs each 500 milliseconds (0.5 s). See the EXEC function block,
tick x ntick0 = 0.05 x 10 = 0.5s

Prerequisites

• REXYGEN Runtime Core and OwsDrv modules must be installed and running on the target device (e.g. Raspberry Pi).
• Owserver (part of the OWFS package) must be installed, correctly configured and running on the target device.
• UNICA 1-Wire sensor module must be connected. The wiring must comply with datasheet - see link below.

Running the example

• The *exec.mdl file is the project main file.
• Open it with REXYGEN Studio.
• Specify the 64-bit ROM ID of the attached sensor module. See the 1-Wire driver manual below.
• Compile and download it to the target device.
• Switch to Watch mode and observe the algorithm.
