Dear Z-Uno followers, we are proud to announce that Z-Uno is now available in Europe! Right now our master distributor for Europe is shipping Z-Uno to various resellers and e-shops around Europe. We will list all available resellers by the end of week to help you get to your local e-shop.

Dear user, we are continuing the development of C++ version of Z-Uno software. Beta version 2.0.3 is out!

What's new:

• millis() function implemented
• Serial avaliable, peek, parseInt, parseFloat
• I2C library added (Wire.h)
• based on I2C library and example for MCP23017
• based on I2C library and example for BMP180
• SPI library added (SPI.h)
• Keypad library added (called ZMEKeypad)
• correct update from 0.6.2, 0.6.3, 0.6.7, 0.7.0 and 2.0.x
• bits operations: bitRead(value, bit), bitSet(value, bit), bitClear(value, bit), bitWrite(value, bit, bitvalue)
• Macro ARDUINO and F_CPU added

Like before, this C++ beta release is available under http://z-uno.z-wave.me/files/z-uno/test-ucxx/package_z-wave.me_index.json URL (please remove stable URL in Arduino IDE settings and put this instead)

In next versions we will add DHT11 and some other examples. We plan to finally release stable C++ version in August to substitute current 0.x.x branch (C only) by C++ enabled 2.x.x branch.

Z-Uno project partially reuses infrastructure of Arduino community. In the same way we want to make it easy to port existing libraries to Z-Uno platform. Most libraries for Arduino uses C++ syntax, while our first versions of compiler was pure C only. To make your life easier we have added C++ support to our compiler. Please follow this instruction to start testing our C++ implementation. Once it gets stable, we will make it the default compiler.

Getting started

Follow our normal instruction but use another link on step 4: http://z-uno.z-wave.me/files/z-uno/test-ucxx/package..., choose latest version on step 5. Now you can start using C++ syntax.

If you are on a version newer than 0.6.2, please first downgrade to 0.6.2. Please see troubleshooting page if you experience problems.

Using own libraries

Put you library files in the same folder as the .ino file of your project. Add #include "your_lib_include_file.h" and reload the sketch.

You can also copy your library folder in ~/.arduino15/packages/Z-Uno/hardware/zw8051/2.0.0/libraries/ (on Linux) or /Users/alexander/Library/Arduino15/packages/Z-Uno/hardware/zw8051/2.0.0/libraries (on Mac OS X) or My Documents\Arduino\libraries\ (on Windows) to use it in many projects.

We are glad to invite you to the Z-Wave booth on CeBIT, where we will show Z-Uno in action!

Hall 13, Stand D72

Please answer few questions about your current or future usage of Z-Uno to let us focus more on your wishes (will take about 2-3 minutes).

You opinion is very important for us!

After valuable feedback from users we decided to design a new Z-Uno design (v3).

New board will have external battery, hence will be smaller and will fit one breadboard.

Better design of battery circuit will enhence live on batteries in FLiRS and sleeping modes.

Better antenna matching and 86mm wire as default option.

Fully compatible with software of existing v2 design.

We expect new boards to be available in late April 2015.

Added XDATA variables initialization, now following code will work correctly


(Prior to this release variables were initialized only inside function, global variables were not. Now global are initialized too.)

Added defines for A0–A3 and PWM1–PWM4 to refer to corresponding pins.

analogRead, analogWrite, digitalWrite, digitalRead, pinMode functions behave now identically to Arduino functions:

• analogRead turns pin to tristate position
• analogWrite turns pin in OUTPUT
• digitalRead and digitalWrite cancels PWM on the pin
• pinMode stops PWM on INPUT and stops ADC on OUTPUT

Improved Interview for channel zero. Now it complies with Z-Wave standards.

Fixed https://github.com/Z-Wave-Me/Z-Uno-Core/issues/51. FLIRS now working correctly.

Added Security (enable Security Command Class) and MultiCmd (enable MultiCmd Command Class) options to Arduino IDE. Turn both off to work with other controllers than Z-Way/RaZberry.

General code improvements

We have successfully held 4 workshops on Chaos Communication Camp 2015 (13-17 Aug) in Hack Center 2.

Thanks to all attendee. That was a great time to share knowledge!

Some photos below (every person on the photos gave us permission to take a picture and share over the Internet).

First version of Z-Uno libraries for Arduino IDE is released!

This version supports all three types of Z-Wave power modes (mains powered, sleeping and FLiRS), basic Arduino functions are implemented (GPIO, PWM, ADC, setup() and loop()), four types of channels: Binary Sensor, Multilevel Sensor, Binary Switch, Multilevel Switch. Support of Arduino IDE 1.6.2
