Re: IRcontroller parameters

(...) The interrupt handler seems to stop the Z-Uno from executing some time consuming instructions, like the Serial.print command for instance. Some background info... According to the official docs : "The duration of an application interrupt routine must be below 80us." (See INS13954 Z-Wave 500 S...

Re: FLiRS - flapping digital pins after wakeup

Almost all MCUs based on 8051 default to "weak pull up" and I think the Z-Uno is no exception to that rule. I occasionally program STC MCUs and they exhibit the same behaviour. In any case, one of the guys of Z-Uno confirmed there is no workaround. I have build an RGBW and the gates of the LED drive...

Re: Z-Wave Gateway

By gateway you mean "controller", like Z-Way or Fibaro HomeCenter? Z-Uno is for developing devices, not controllers. Though, for sake of completeness, you might be able to turn a Z-Uno into a controller by flashing it with the published generic image (in the Silabs SDK), but there might be no way ba...

Re: [solved] FLiRS - zunoSetBeamCountWU() question

Thanks for the feedback. Indeed, there are 2 issues with sleep: pin state and NZRAM. Have fun with your Z-Uno!

Re: Z-UNO based weather Station (German description)

Regarding BH1750: it supports 0.5, 1 and 4 Lux resolution... With 4 Lux resolution you should be able to get higher values than 32k, but then it is not very sensitive in dark light. So Ideally, you'd have to measure at 4 Lux resolution, then if it is below 16.000 switch to 1 Lux resolution. I am not...

Re: FLiRS - zunoSetBeamCountWU() question

I wrote this sketch some time ago: https://github.com/petergebruers/Z-Uno-FLiRS-LED-DEMO And I noted: "If you notice an unexpected "blink" of the LED, this is "by design". The Z-Uno initializes the pins, and it takes some time to get the LED pin back to output. The only way I can think of, to avoid ...

Silabs publishes Z-Wave SDK, extra documentation, sniffer and PC controller and gateway

This is great news for all technically inclined! After partial release by Sigma, last year, the new owner "Silabs" decided to publish a lot more useful stuff: See this excellent post by Mr "tinman" on the fibaro forum, to get you started. (Note, I'm involved in that discussion as well... so I might ...

Re: Shield for Z-Uno

(...) No protection - we just turn it on/off. Why do you need protection if the wiring is correct? True! I need it, when the wiring is incorrect ;) Maybe the mosfet is so powerful, it can survive a short circuit and drag the supply down...? If I would make my own RGBW I would use "Smart Low Side Po...

Re: Shield for Z-Uno

RGBW = short circuit protected? With current measurement?
