Is it working for Raspberry Pi 3?

[drohm]

Hi, sorry, just getting back into swing again after the holidays.

Could you try using different pins? Since you're using GPIO.BOARD, try 12 (data) and 16 (clk).

[BLionS]

@poguez try connect a pull-up resistor 1k ohm between Vcc and DataPin.

PD: This work to me.

I connect 10K ohm pull-up resistor between Vcc (3.3V) and DataPin, it worked. Thank you for your advice @BLionS. I also appreciate for this great library @drohm.

[drohm]

Can you provide more information?

What specifically isn't working? What have you tried? Can you provide the output from doing pip list --format=columns at the command line? How are you using the library, which script? What error are you getting? What's the output?

[poguez]

Any thoughts on this?

[poguez]

No luck, same error.

[drohm]

Okay, I just tested this on my pi3 in a fresh virtualenv. I pip installed RPi.GPIO and pi-sht1x and it worked fine for me.

Command:
(pi-sht1x-dev) drohm@scifpi01:~/dev/pi-sht1x/examples$ python sensor.py 18 23 -g 'BCM'

Wiring setup:

Output:

Run these commands for me and paste the output:

Also, I'm not sure if this is related, but I noticed that your version of pip and setuptools is pretty old, upgrade them. My pip list output:

Package    Version
---------- -------
pi-sht1x   1.0.9  
pip        9.0.1  
RPi.GPIO   0.6.3  
setuptools 38.2.5 
wheel      0.30.0 

While you're at it, upgrade wheel as well.

@poguez Any updates?
