Getting Temperature/Humidity/Ambient Light data with Python

Posted by: Yomet - 09-28-2016, 03:34 PM - Forum: POT modules - Replies (8)

Hi,

I have tried to get data from both the Temp/Humidity and the Ambient Light sensor by using python and python-smbus. I have found and read the tech docs of both adapters as specified by Pine64 but have not gotten all the way to reading the correct data, i.e. I get data from the T/H sensor but it says that it's -5 C inside and I don't believe that since I'm sitting in short-sleeves... Smile

I also found the posts from khgoh (http://forum.pine64.org/showthread.php?tid=231&page=3) and skimmed through the source code for the WifiRemoteI2C server but that is in C (C++) and does not help me at all, or rather, it does not help me solving it in python...

My problem is that the value I get from the T/H sensor does not convert correctly into the ambient temperature and relative humidity.

I would really appreciate if someone told me where I am going wrong and how to correct it.

Many thanks

DS

Source:

Code:
import smbus

import time

bus = smbus.SMBus(1)

address = 0x40

cmd_temp = 0xE3

cmd_humid = 0xE5

temp = 0L

humid = 0L

temp = bus.read_word_data(address, cmd_humid)

print "RH read_word_data returns ", humid

print ""

humid = 125.0 * humid / 65536 - 6

print "RH: ", humid, " %"

print ""

print ""

temp = bus.read_word_data(address, cmd_temp)

print "Temp read_word_data returns ", temp

print ""

temp = 175.72 * temp / 65536 - 46.85

print "Temperature: ", temp, " C"

print ""

print ""

Output:

Code:
debian@pine64:~/i2c$ python getTemp2.py 

RH read_word_data returns  0

RH:  -6.0  %

Temp read_word_data returns  10341

Temperature:  -19.1229412842  C

surveillance control center for ip cameras

Posted by: Miguel Campos - 09-28-2016, 08:41 AM - Forum: Pine A64 Projects, Ideas and Tutorials - No Replies

Hi guys
After some time having the pine finally I have decided a practical use for it.
I'm getting an ip camera for testing sricam sp013 and I will try to create some kind of control center with my pine.
so I can control then without sending data to Chinese pages :-)
and I can access it through internet.

Has any one try anything like this?
any advice on which can be a good point to start?

Regards.

Time Capsule - failing getting libkrb5-dev

Posted by: wojciech_czyz - 09-28-2016, 08:11 AM - Forum: Debian - Replies (1)

Hi,

I have been trying to get working Time Capsule using Debian of Pine64, yet following many of the threads there are always some problems.
I am stuck getting libkrb5-dev:

Code:
sudo apt-get install build-essential devscripts debhelper cdbs autotools-dev dh-buildinfo libdb-dev libwrap0-dev libpam0g-dev libcups2-dev libkrb5-dev libltdl3-dev libgcrypt11-dev libcrack2-dev libavahi-client-dev libldap2-dev libacl1-dev libevent-dev d-shlibs dh-systemd avahi-daemon libc6-dev libnss-mdns

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
libkrb5-dev : Depends: krb5-multidev (= 1.12.1+dfsg-19+deb8u2) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

I used the image from Pine64.pro

Debian Mate (3.10.102 BSP 2), Released Jul 18 2016

Updated kernel, uboot and packages, yet always get this.

Is there solution for this?

Thank you!
Wojciech

3,5mm audio out not working

Posted by: MikkoL - 09-28-2016, 01:32 AM - Forum: Android on Pine A64(+) - Replies (9)

Hello,

I don't seem to be getting audio from 3,5mm jack working. I have tried ayufan's Android 5.1 and 7.0 builds (TV and no TV), to no luck whatsoever. Also tried plugging the jack only after a reboot, but still nothing. Sound comes only through HDMI.

Can anybody help? Or confirm that it really doesn't work? From what I read, this has been an issue before, but some reports at least from the Linux side are saying it shold work.

Mikko

Received a bad LCD, can't get support.

Posted by: bryanlyon - 09-26-2016, 12:28 PM - Forum: LCD and Touch Panel - Replies (3)

	So, I received a bad LCD. The cable on the back of the LCD arrived with a small tear in it. I've tried over and over to get support from pine64 staff with about a half dozen emails, and support tickets but haven't gotten any help. Does anyone know if I can easily replace the cable myself? I really want to use my LCD and am fairly sure I'll never get support from pine64 to get it fixed. Thanks!
