Hi all,

I'm planning to use the DS18B20 too.
I open an issue here : https://github.com/OnionIoT/Onion-Docs/issues/18

Let see the onion response

Now fixed as per https://community.onion.io/topic/1310/1-wire-temperature-sensor-ds18b20-on-omega2/19

@zinuzoid it works for b137 but the issue is that it doesn't have the SD card detect.. which very irritating

@WereCatf
I downloaden the request package : https://dl.dropboxusercontent.com/u/11811685/checkHumidity.tar.gz

Unpacked it:
tar -zxvf checkHumidity.tar.gz

Did the chmod:
chmod -R 755 /root/checkHumidity/bin/checkHumidity

I checked the firmware
root@Omega-5101:~# oupgrade

Device Firmware Version: 0.1.9 b149
Checking latest version online...
Repo Firmware Version: 0.1.9 b149
Comparing version numbers
Device firmware is up to date!

But I'm getting a segmation fault:

root@Omega-5101:~/checkHumidity/bin# ./checkHumidity 20 DHT11
Segmentation fault

I tried different GPIO pin, all gave the same result

[WereCatf]

@Oene-Bakker This has already been answered multiple times in this thread..

[Oene Bakker]

@WereCatf
Yes, sorry was a bit too quick

So went back to the old firmware

root@Omega-5101:~/checkHumidity/bin# oupgrade -c

Device Firmware Version: 0.1.6 b137
Checking latest version online...
Repo Firmware Version: 0.1.9 b149
Comparing version numbers
New firmware version available, need to upgrade device firmware

Now I'm getting:
root@Omega-5101:~/checkHumidity/bin# ./checkHumidity 20 DHT11
-255.000000
-255.000000

Checked the wiring and tried different GPIO's all with the same result

[WereCatf]

@Oene-Bakker Do you have a pull-up resistor on it?

[Oene Bakker]

@WereCatf
No but when I use a 10K pull up I get the same results

root@Omega-5101:~/checkHumidity/bin# ./checkHumidity 20 DHT11
-255.000000
-255.000000

Also tried lower values 4.7K and 1K but that didn't work also

@Oene-Bakker Any luck with this? I have an Omega 1 and have the same problem albeit with the older version of checkHumidity.

[Oene Bakker]

@Prakhar-Birla no sorry. I stopped trying.

Dropbox stays the file is no longer available. Is there an alternate url to get checkHumidity for the Omega2? Please and thanks!

[James Harding]

+1 on looking for the Omega2 compiled version of this. Dropbox link didn't work for me either.

[troy]

+1 looking for the Omega2 ver as well

[Alexander Nedzelsky]

+1 still looking

[Felipe Cespedes]

Any updates about the binaries for omega2?

Hi all
Good news. I migrated original code successfully to work on Omega2!
See https://github.com/h0l0gram/omega2-checkHumidity for binary and source.

Make sure your Omega2 has firmware >=0.1.10 b160 or it won't work.
