Re: Interrupts in 2.0.8

I am using GPT and two interupts as well with my weather station project. Is running stable for some months now. Only important thing is to have only limited code within the interupt routines. In my case I only have a counter within the routine. If you don't follow that advice the application might ...

Z-UNO based weather Station (German description)

Over the last couple of months i build a weather station using Z-UNO. There are two articles describing the solution and integration into Fibaro HC2(German) https://www.siio.de/z-wave-wetterstation-diy-teil-1-z-uno-hw-sw/ https://www.siio.de/z-wave-wetterstation-diy-teil-2-fibaro-vd/ The solution is...

Re: Nextion and z-uno

You could use Nextion without library.

Re: Quick-fix for library's problems in Z-Uno?

Hello, you don't need to go via another microcontroller to communicate with MCP4725. I2C just works fine and if you address the chip directly without going via a library you shouldn't have any issues. Below code I found on the web and it addresses the I2C interface directly. Not sure whether you nee...

Re: How to transport data to Z-UNO

Andreas, thanks for your extensive answer. Maybe I need to describe in a bit more details what I want to achieve: I want to keep a list with all doors and windows device ID and Names in Z-UNO. One option is to hardcode in usercode, or store in EEPROM with a separate code processed once to store and ...

How to transport data to Z-UNO

Is there a way to transport data from Z_Wave controller to Z-UNO other then the quite limited ZUNO_SWITCH_MULTILEVEL which only allows to send 0-99? My plan would be to send actor ID's and names to Z-UNO, store them in EEPROM. If there is a chance to send at least eg. 4bytes at the same time it woul...

Re: HYT 939(HYTxxx) Accurate temperature and humidity I2C se

Tested int for variable and int for getter over the weekend. This combination doesn't work either. Seems like getter requires an unsigned variable not as described in documentation signed! Getter in all examples is correctly unsigned, but some of the temperature examples use signed variables for the...

Re: HYT 939(HYTxxx) Accurate temperature and humidity I2C se

OK, Loks like signed - signed and unsigned -unsigned works, but not a combination of them.
I am out of contry and can only test on the weekend.

Re: HYT 939(HYTxxx) Accurate temperature and humidity I2C se

Michael, Tonight i had a real World test. Temperature dropped bellow 0. Hat one Sensor with int and one with unsigned int. The one with int went flad at 0 degrees. So type matters, like i though. Direct conversion doesnt show Same result as from Byte. Guess we need to get a Statement from devolopers...

Re: HYT 939(HYTxxx) Accurate temperature and humidity I2C se

Michael,

did test your code.
Same result for int and unsigned integer.
Seems z_UNO does the correct conversion to word type automatically.
Maybe I mixed up "getter variable type" at some time and used int there.

Will update original posting.

thanks, Markus
