Hello I have Unipi 1.1 board and as written here https://kb.unipi.technology/en:automation:02-glossary:analog-inputs-hidden#measuring_resistance
I would try to use PT100 on AI , what resistance I need ? may be a 10k is good?
Thanks.

Hello I have istalled the Node red image on Unipi 1.1 but no desktop...only command line. How to RU or install the PI desktop please??

Hello ! I have unipi 1.1 and I need to measure temperature and Humidity separately or in one probe.

I want to use the 2 AI inpusts channels (they misure only 0-10V) ..it's diffcult to find converters from PT100 or NTC to 0 - 10V .... what do you suggest me?

I want know if there is a SPI port in Unipi 1.1 to use SPI devices, for example Adafruit:
SPI Logic pins: SCK - This is the SPI Clock pin, its an input to the chip SDO - this is the Serial Data Out / Master In Slave Out pin, for data sent from the MAX31865 to your processor SDI - this is the Serial Data In / Master Out Slave In pin, for data sent from your processor to the MAX31865 CS - this is the Chip Select pin, drop it low to start an SPI transaction. Its an input to the chip

thank you!

Hello!
how to Set the clock via libraries as DTUtils OR SysTimeRtcGet/SysTimeRtcSet functions?

I can do it but the raspy is connceted to internet and timezone is set automatically by NTP.
So I can't set a strange clock (i don't know at the moment the time zone where will be installed so I can't set in the raspy).

There is a way to set the timezone from codesys? I tired but doesn't work.

Thank you very much!

Hello I tried to do a clean all and now is working.

Hello I followed the 2 pdf of configuration
All other IO are working well.

1-
I m using 2 REAL variabiles ana1 , ana2
I applied 5 V dc between AI+ and AI-
The AI1 and AI2 show always 0 volts...

Why ?

Here the settings for cycle..

2- How to enable de DI 13 and 14? Have I to change some dip switch? or SW?
Thanks

Intresting! I would partecipate as Codesys developer!
