Melexis I2C Stick

Introduction

Yet another I2C interface...
However our mlx-i2c-stick aims to:

  • Provide a low cost interface towards our 3.3V supplied sensors who uses the I2C communication bus.
  • Use as much as possbile off-the-shelf available material/modules.
  • Create a friction free getting starting experience.
  • Enable prototyping using its small sensor boards.
  • Provide a reference code (firmware) based on the arduino platform; snippets can be used in end-user-applications.

What is mlx-i2c-stick?

Microcontroller on one hand a USB CDC UART and on the other a I2C master at 3.3V.
We provide open source firmware and an userinterface to easily get started with our I2C/3.3V based sensors.

Getting started

  1. Click the open button on the top right of the screen.
  2. Select the serial port of the mlx-i2c-stick.
  3. Enable the chart (transient or spatial)
  4. The Scan button will scan the I2C bus for slaves
  5. The Start button will start continiously measuring all recognised slaves
  6. The Stop button will stop continiously measuring the slaves
  7. The slaves will appear on the left column.
  8. The MV button will initiate a singlee 'Measure Values' action.
  9. The terminal let you do other cool stuff, more on this later.

The hardware

Public off-the-shelve Hardware

Melexis Sensor board Hardware

Our sensors boards minimizes the board size to the bare minimum while we maximize the capability to use the sensor boards in a prototype by having the sensor mounted at opposite site as the connector and other components.
