(...) 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...

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...

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...

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

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...

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 ...

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 ...

(...) 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...

RGBW = short circuit protected? With current measurement?
