This new software update for Z-Uno introduces many new features, allows you to use modern Arduino IDE 1.8.5 and prepares Z-Uno for the most secure IoT protocol - Z-Wave Security S2 - that will be release in the next 2.1.2.

What's new in 2.1.1?

New features:

  • Arduino IDE 1.6.5 and 1.8.5 are now supported. You can now use the latest Arduino IDE with Z-Uno!
  • Added Japonese, Korean and Taiwanese frequencies.
  • Number of Z-Uno channels rised to 32! You can make 32 devices in one.
  • Added support for up to 32 user defined configuration parameters to make your sketches even more flexible.
  • Z-Uno can wake up on low and high INT1 - this allows to go into sleep mode on any state of INT1. Save more battery in your sensor!
  • Stack overflow and system errors are reported to the controller and/or to the UART0. Arduino IDE Tools menu allows to turn it on/off. This should make your debugging easier.
  • User defined battery measurement allows to personalize battery reports for your project.
  • Added the possibility to measure the voltage on the 3V pin using analogRead() function.
  • Added function zunoSetBeamCountWU() to instruct Z-Uno in FLiRS mode to wake up after several second even if there were no packets received. This allows to make always reachable battery powered sensors.
  • In Arduino IDE Tools menu one more item added - clean EEPROM. Can clean user data, system data or all data (like reset to factory default).
Bug fixes
  • Fixed wakeup on Key Scanner (broken in 2.1.0)
  • Fixed FLIRS not reporting without a delay in the loop. Now delay is not needed anymore.
  • Fixed handler calling when devices is sent into sleep by user.
  • memset fixed
  • No need to downgrade to the previous version to upgrade from test build to a stable one
  • Few examples changed to adop the changes above

And a lot of internal changes (see our forum for more details).

Our next ambitious goal is to release and certify an S2 capable Z-Uno!

To illustrate the power of Z-Uno we have made those new examples::

To install this new release follow simple instructions.

Documentation on Z-Uno web site was also revised and updated to host new functions description.

We are happy to announce a new Z-Uno release! This software update of Z-Uno is introducing many new features and fixes some bugs found in 2.0.9.

What's new in 2.1.0?

New example added (can be found in File→Examples→Z-Uno in Arduino IDE or on the site):

  • Z-Uno as a modem — communicate with Z-Uno via AT commands.
    This new sketch allows to use Z-Uno as a modem like it is with Bluetooth HM-10. Connect Z-Uno you your smart devices to make the Z-Wave enabled!

    This sketch also allows to report values from your PC or Arduino to your existing Z-Wave controller.
  • NeoPixel illustrates how to control WS2811/WS2812 LEDs right from your Z-Uno.
  • Multiple DS18B20 creates as many channels as there are temperature sensors connected

New features:

  • New channel types added:
    • Blinds (similiar to Switch Multilevel, but shows up as blinds in controllers)
    • Siren (similiar to Switch Binary, but shows up as a siren) — can be sleeping (FLiRS) and run on battaries
    • Valve control (also called Flow Stop, similiar to Switch Binary, but shows up as a valve control) — can be sleeping (FLiRS) and run on battaries
  • Now Z-Uno channels and association groups can be configured depending on the peripherals - same sketch can adopt to the environment. For example autodetect all DS18B20 temperature sensors on the 1-wire bus and render the corresponding channels. Or read configuration from UART and create channels and groups corresponding to that data. Or connect Bluetooth modem with Z-Uno and create a Bluetooth-to-Z-Wave gateway. There might be many ideas! See full description.
  • Learn mode can not be initiated from the sketch. This allows to start learn mode via USB, UART or any other bus from another chip.

Libraries

  • NeoPixel implements support of WS2811 and WS2812. The library is compatible with Arduino style.

This new C++ release is available under http://z-uno.z-wave.me/files/z-uno/package_z-wave.me_index.json URL (follow instructions).

We are happy to announce a new Z-Uno release! This software update of Z-Uno is fixing a lot of bugs of the previous version 2.0.8 and earlier.

What's new in 2.0.9?

New example added (can be found in File→Examples→Z-Uno in Arduino IDE):

New features:

  • Libraries
  • Fixes:

    • Fixed digitalRead with constant pin reference (broken since 2.0.8).
    • Fixed ADC wrong values after Z-Uno wakeup (broken since the beginning).
    • Fixed user readable output on wrong s_pin usage (not in 9-16 range, broken since 2.0.8).
    • Fixed problem with pins 17-23 (fixed in 2.0.7, but broken again in 2.0.8).

    Improvements:

    • Added atoi, atol, atof definitions in headers.
    • Interrupt handlers can be defined not only in sketch file, but in libs too (used in the new ZUNO_SERVO)

    This new C++ release is available under http://z-uno.z-wave.me/files/z-uno/package_z-wave.me_index.json URL (follow instructions).

    We are happy to announce a new Z-Uno release! This software update of Z-Uno fixes some issues from 2.0.7 version and brings many new features to your Z-Uno.

    What's new in 2.0.8?

    New examples added (can be found in File→Examples→Z-Uno in Arduino IDE):

    New features:

    • External interrupts of the Z-Wave chip: INT0 (pin 17), INT1 (pin 18), ZEROX (pin 3). Interrupt handler should be defined in global range via ZUNO_SETUP_ISR_*(isr_handler), where isr_handler is the name of the corresponding function to call on interrupt.
      • ZUNO_SETUP_ISR_INT0(int0_handler)
      • ZUNO_SETUP_ISR_INT1(int1_handler)
      • ZUNO_SETUP_ISR_ZEROX(int_zeroX_handler)
      NB! The code in the handler should be as fast as possible and should not contain ANY function calls except few specified below.

      Trigger mode is defined using function zunoExtIntMode(byte int_num, byte mode). Allowed values are for int_num are:
      • ZUNO_EXT_INT0
      • ZUNO_EXT_INT1
      • ZUNO_EXT_ZEROX
      for mode are:
      • CHANGE (value change)
      • FALLING (high to low falling)
      • RISING (low to high rising)
    • General Purpose Timer (GPT) is now available. interrupt handler can be set via ZUNO_SETUP_ISR_GPTIMER(gpt_handler), where gpt_handler - is the handler function name (like for interrupts handlers). Timer is configured using the following functions:
      • zunoGPTInit(byte flags) — set timer mode:
        • ZUNO_GPT_SCALE1024 — specify tick frequency as 32MHZ/1024, otherwise default 4MHZ is used.
        • ZUNO_GPT_IMWRITE — write new value immediately instead of waiting for timer to reach zero
        • ZUNO_GPT_CYCLIC — reload the timer on reaching zero — otherwise timer triggers only once
      • zunoGPTEnable(byte bEnable) — enable/disable timer
      • zunoGPTSet(word interval) — defines the number of ticks before interrupt happens.
      NB! GPT can not be used together with PWM. Don't use analogWrite while using timers
    • New 1 ms timer. Unlike GPT, this timer is not so accurate, but have no restrictions on PWM. Defined using ZUNO_SETUP_ISR_1MSTIMER(m1ms_handler)
    • ADC (analogRead) resolution can be changed using function analogReadResolution(byte resolution). Resolution can be in range 1-12 bits. Most popular are:
      • 10 bits (default) — Arduino Uno compatibility mode
      • 12 bits — maximum possible in Z-Uno
      • 8 bits — can save energy in battery devices (uses special mode of Z-Wave MCU to make ADC faster)
    • Possibility to choose Reference for ADC using analogReference(byte ref). Possible values are (bitmask flags)::
      • ADC_HIGH_EXTERNAL — use A0 pin as upper reference voltage
      • ADC_HIGH_INTERNAL — use internal voltage reference 1.2 V as upper reference voltage (NB! there might be a ±10% drift from Z-Uno to Z-Uno, but constant for a particular Z-Uno!)
      • ADC_HIGH_VCC — use Vcc as upper reference voltage (default)
      • ADC_LOW_EXTERNAL — use A1 pin as lower reference voltage
      • ADC_LOW_GND — use GND as lower reference voltage (default)
      • Pre-defined (Arduino-like) values:
        • DEFAULT = (ADC_HIGH_VCC | ADC_LOW_GND)
        • INTERNAL = (ADC_HIGH_INTERNAL | ADC_LOW_GND)
        • EXTERNAL = (ADC_HIGH_EXTERNAL | ADC_LOW_GND)
    • Possibility to define PWM resolution using function analogWriteResolution(byte res). Resolution can be in range 1-16 bits. Most popular:
      • 8 — like in Arduino Uno (default)
      • 16 — maximal possible in Z-Uno
    • Libraries
      • New library ZUNO_AM2030 temperature & humidity AM2030 I2C sensor.
      • New library ZUNO_PN532 NXP PN532 I2C NFC/RFID sensor.
      • New library ZUNO_LPS3310 LPS3310 I2C pressure sensor.

    Fixes:

    • Error that lead to Z-Uno being unreachable after new sketch load (reset was required).
    • Problems with ADC wrong errors and input resistance (pullup was accidentelly turned on).
    • Problems with data loss on UART1/UART0 on speed bigger than 9.6 kbps. UART reworked to use buffering and MCU facilities (DMA).
    • Problems with pins 17-23 being changed on Z-Wave packet send.
    • Failed I2C communication with Arduino and other MCUs.

    Improvements:

    • IR input buffer size rised from 200 to 300 bytes - now IR commands up to 9 bytes can be captured (used by most A/C remotes).
    • Allowed to use delay() in setup(). This call is blocking.

    This new C++ release is available under http://z-uno.z-wave.me/files/z-uno/package_z-wave.me_index.json URL (follow instructions).

    Documentation on Z-Uno web site was also revised and updated to host new functions description.

      • ZUNO_ONEWIRE lib can now scan the bus (search() function)
      • ZUNO_DS18B20 lib can search for all DS18B20 on the OneWire bus (findAllSensors and scanAloneSensor functions). Added example: DS18B20Sacnner
      • ZMEKeypad new function isIdle() added to the lib to check if buttons are active or idle (to go to sleep only on idle)
    • Compatibility: new parameter #12 added for correct work of Sensor Binary/Notification channels in Fibaro Home Center 2/Lite.

    Fixes:

    • uCxx Compiler
      • Multidimensional arrays definition fixed
      • Dots in file names now work
      • // comments in ZUNO_* macro work
      • Warinings on local char * supressed
