Hi!
Can yu pls give me same starting points how to read sensor in title over I2C or similar couse this sensors are
not based on I2C protocol...

Reagrds T.
Tnx!
Hello,
Could you write more details? What module are you using and what results or problems you have?
It looks that it could be possible to communicate with this sensor over i2c but you need to try and test.
You should have no problems with this sensor:

Hello!
I'm uising Cinterion Concept Board...
Been trying to use simple "bit banging" method for sht7x.. over Gpio inputs, but now i want to know how to switch pins to inputs in real time is it possible over AT commands? and are there any bitShiftOut methods and bitShiftIn..?
But looks that i'm better off to use device that supports I2c or Spi..

Hello,
The best solution would be to use the device with i2c or SPI interface.
You can switch the GPIO pins directions of Concept Board's external interfaces via i2c - it is described in the hardware description for concept board. Besides that you need to configure this for the module with AT commands or Java code.
I don't think that GPIO will work. It's rather for setting or reading the state of some line and not for time solutions with so strict timing constraints. So I'd rather try with i2c.

HI once again!
So in theory it could work.... But indeed i will chose the more elegant way so i2c supported sensors!
Tnx and have a good day ;)
