Re: Z-UNO + RS232

Tht's ok, that is a "typical rs232 converter IC" According to the datasheet: "Operates With 3-V to 5.5-V VCC Supply" BTW I have not used RS232 in 10 years :-) my memory is rusty. There is a whole bunch of signals like CTS and DTR that might need to be set, before the UPS wants to transmit. I do not ...

Re: Z-UNO + RS232

Yes. The resistors are there, in case you accidentilly connect the uno to 5 or 12 V. Any partnumber on that chip.

Re: Z-Wave Gateway

My implementation is "power hungry" if you consider 40 mA at 3.3 V "power hungry"... I don not think you can power down the CO sensor. So trying to optimize the Z-Uno seems not worth it in this case.The Z-Uno is always on. You could make devices (actor + sensor) that run with less than 1 mA (and eve...

Re: Z-uno Nfc badge reader

I never saw a "text" variable. I think Z-Wave does allow a manufacturer to transfer arbitrary data, but it is somewhat special. But even If Z-Uno supported this... you still need some support on the controller, so that would be your next problem. If you own a Fibaro RGBW you might have seen it suppo...

Re: Z-UNO + RS232

What chip is on that converter board? I suspect possible issues if the nominal voltage is 5 V. The Z-Uno outputs max 3.3 V (actually closer to 3.1 V). That might not be high enough to signify "1". Also, it does not accept more than 3.3 V on any pin, higher voltage with no current limit damages the Z...

Re: Z-Wave Gateway

Yes, your Z-Uno can implement a relay and/or a dimmer and/or a sensor at the same time. For instance, I have a n RGBW light behind my TV and it also has a CO2 sensor at the same time.

Hah! the same relay :-)

Your project sounds interesting. I look forward to see your post!

Re: FLiRS - flapping digital pins after wakeup

I did not want to insult you... It is difficult to get to know each other from a few posts. I fully agree, the flapping is an issue! Not for this simple LED, but imagine you want to drive a relay, to switch an appliance... I would work around it this way: first use a bistable relay with 2 coils. The...

Re: FLiRS - flapping digital pins after wakeup

Glad I could help.

I think you underestimate how many times setup() gets called... it is each time the device wakes up, and there are many reasons. It will wake up, for instance, when you "poll" the device because that is a radio transmission. so that will reset the pins and run setup().

Re: FLiRS - flapping digital pins after wakeup

It is not you... wake up is tricky! I see at least one issue... In setup, you have to read NZRAM and set the pins according to that. So, after the devices wakes up, first the pins "flap" as you said, but then in setup you set them to output and also on or off, as indicated by the NZRAM. In my sketch...
