harmongt01 commented 6 years ago

Hi Simon,

I had to reinstall everything. I saved a backup but I think I'm missing something. I get the following error when trying to import batteries:

root@beaglebone:/mnt/SD/BatteryMonitor# python Python 2.7.13 (default, Jan 19 2017, 14:48:08) [GCC 6.3.0 20170118] on linux2 Type "help", "copyright", "credits" or "license" for more information.

Any ideas?

Thanks, George

Hi George, Nice to hear you are still around. I have done a major upgrade of the software which requires Python3. Did you reclone my software form Github? If so you will have to upgrade to Python 3. You will also need to add the line
interface = 'from getatod import Raw'
to the [Files] section of battery.cfg

Hi Simon,

I was not successful with upgrading to Python3 yet. So I did cloned a fork I made. This got me a little further now. Is there any benefit for me to move to the newer code or resolve this as it is? I think it gave me everything I needed.

Hi George, That looks like an old version of the code before I modified it for your multiple power sources. What are the problems you are having with upgrading to Python3?

I found that Python3 was already preloaded on my Beaglebone. You just have to type the commend python3 rather than python I would get Python3 working and clone a fresh copy of my new code and use it with your Battery.cfg file with the extra line I stated in my last reply and the summary.1cell.

Simon

harmongt01 commented 6 years ago

Well you are right. I remember running it in the past too now that you mentioned it. So I will clone your latest code and add the line. I'll let you know how that goes.

Thanks! George

Hi Simon,

Ok, one step forward, two steps back again :)

I reinstalled everything from scratch so I may not have this module installed in the right place.

harmongt01 commented 6 years ago

I found where someone had a similar problem. They reinstalled Adafruit_Python_GPIO using python3 so I tried that. Now the error is different but maybe I should hold here before I get too deep in trouble:

simat commented 6 years ago

I had forgotten about having to reload the Adafruit library, I will update my documentation.

Here is the link with instructions on how to install the Adafruit python3 library.

Hi Simon,

I tried the steps but I am having some issue. Keep running into some dependency problem with chromium that seems to be causing a problem:

Try changing root@beaglebone:~/Adafruit_Python_ADS1x15# python setup.py install to root@beaglebone:~/Adafruit_Python_ADS1x15# python3 setup.py install If this fails try the Python Package Index Install instructions further down the Adafruit installation page instructions.

Should have read to the end of your last message. Don't bother using pip the first option should work. I am fairly sure that is how I did it.

harmongt01 commented 6 years ago

Tried the command you suggested and got the following result when trying to run.

root@beaglebone:~/Adafruit_Python_ADS1x15# cd /mnt/SD/BatteryMonitor/ root@beaglebone:/mnt/SD/BatteryMonitor# python3 Python 3.5.3 (default, Jan 19 2017, 14:11:04) [GCC 6.3.0 20170118] on linux Type "help", "copyright", "credits" or "license" for more information.

I will Python Package Index Install instructions tomorrow.

Thanks, George

simat commented 6 years ago

Ah, I remember now, Adafruit have changed the driver.

To work with the new driver try your battery.cfg that I have modified. batteryGeorge.cfg.txt

harmongt01 commented 6 years ago

results are different:

simat commented 6 years ago

Sorry, I left out the Interface line in the Files section.

You will need to add the line interface = 'from getatod import Raw' to the [Files] section of battery.cfg

simat commented 6 years ago

I have finally had a look at the how to do proper versioning with Git. You will see there are now 3 releases on a link on the code page. Each one of these is a snapshot at a particular time.

You can always go back to any point using the commits link

harmongt01 commented 6 years ago

I added the interface line to my saved backup file so I don't keep running into that.

Do you think I should try one of the releases you added? After adding the interface line to battery.cfg I am back to getting the following error:

Python 3.5.3 (default, Jan 19 2017, 14:11:04) [GCC 6.3.0 20170118] on linux Type "help", "copyright", "credits" or "license" for more information.

simat commented 6 years ago

Hi George, Hopefully we are both online. You have to use the batteryGeorge.cfg.txt that I attached to a day ago.

Add the interface line to that file and rename it battery.cfg

I just had a look at the config file again. Sorry I have made another mistake, need a new brain! change this line atod1 = 'AtoD.ADS1x15(address=0x49,ic=0x01,busnum=2)' to atod1 = 'AtoD.ADS1x15(address=0x49,busnum=2)'

harmongt01 commented 6 years ago

Hi Simon,

I am using the batteryGeorge.cfg file you sent me. But I get that same error.

Python 3.5.3 (default, Jan 19 2017, 14:11:04) [GCC 6.3.0 20170118] on linux Type "help", "copyright", "credits" or "license" for more information.

simat commented 6 years ago

I edited my last comment and added "I just had a look at the config file again. Sorry I have made another mistake, need a new brain! change this line atod1 = 'AtoD.ADS1x15(address=0x49,ic=0x01,busnum=2)' to atod1 = 'AtoD.ADS1x15(address=0x49,busnum=2)' "

That should fix it, as you can see from the last line of the error it is getting an unexpected arguement 'ic'

simat commented 6 years ago

Hi George, It is a little hard for me to test your configuration but I have loaded my BMS software with your config file.

I have found some other errors. The attached file hopefully has fixed all the problems batteryGeorge.cfg.txt It now compiles on my computer but gives an error when it tries to access the non existent I2C bus on my computer.

So hopefully this is it! Simon

harmongt01 commented 6 years ago

HI Simon,

By the way thanks again for helping me out with this.

A couple steps forward I think. Now it gives the following error about GPIO

Python 3.5.3 (default, Jan 19 2017, 14:11:04) [GCC 6.3.0 20170118] on linux Type "help", "copyright", "credits" or "license" for more information.

simat commented 6 years ago

Hi George, Adafruit have changed the way they do IO on the Beaglebone and I am having a battle to get it working.

There is currently a test alarm alarm = ['GPIO.setup("P8_10", GPIO.OUT)', 'test=minvolts<2.8 or maxvolts>3.60', 'GPIO.output("P8_10", GPIO.HIGH)', \ 'test=minvolts>2.9 and maxvolts<3.59', 'GPIO.output("P8_10", GPIO.LOW)']

In the alarms section of the config file. I assume you are not using this, if so you could delete it or comment it out. This should solve the GPIO problem.

harmongt01 commented 6 years ago

I am having this strange chromium dependency problem that seems to be causing problems to install other things like jre.

Hi Simon,

This is after commenting out the alarm you mentioned.

I must have multiple issues :)

harmongt01 commented 6 years ago

Hi Simon,

I did not comment out the alarm section correctly. The program is running now without error 👍

harmongt01 commented 6 years ago

Hi Simon,

Now that I have your program running, I see the voltage reading is now in the 9V range but it should be in the 13v range. I notice the changes to your cfg file but not sure I understand how to properly calibrate things.

For example the old AtoDs and VoltageInputs were the following: [AtoDs] atod0 = 'AtoD.ADS1x15(busnum=2,address=0x48,ic=0x01, debug=True)' atod1 = 'AtoD.ADS1x15(busnum=2,address=0x49,ic=0x01, debug=True)' atod2 = 'AtoD.ADS1x15(busnum=2,address=0x4A,ic=0x01, debug=True)'

[VoltageInputs] v1 = 'atod0.readADCSingleEnded(channel=0, pga=4096, sps=250)'

The new ones are: [AtoDs] atod0 = 'AtoD.ADS1115(address=0x48,busnum=2)' atod1 = 'AtoD.ADS1115(address=0x49,busnum=2)' atod2 = 'AtoD.ADS1115(address=0x4A,busnum=2)'

[VoltageInputs] v1 = 'atod0.read_adc(0, gain=2)*0.06250197'

These changes are the same in CurrentInputs also. I read through some of your updates to the instructions area of github but I'm not quite up to speed on it. Maybe it's still a work in progress.

What steps should I follow to adjust voltage? I will want to calibrate the current as well after that. Will that calibration still be similar as before?

Thanks, George

simat commented 6 years ago

Hi George,

I have hopefully made the calibration easier with three new programs. See the Calibrate wiki page to get details.

Simon

harmongt01 commented 6 years ago

Hey Simon,

Something is not right with my voltage measurement. My wiring and voltage divider should be exactly the same as before. Now the voltage is being recorded by the program as always 9.391 with no fluctuation as if it is not reading anything from the batteries. When I disconnect the positive lead going from my voltage divider to the ADS then the voltage reading changes to another constant of 0. something. So the lead from the voltage divider is providing something.

Also, I do not really understand how to use your calibration to adjust the voltage measurement.

But it looks like I have two issues. First, the voltage should always be fluctuating even if the reading is not the expected 13.x volts. Second, how do I use the calibration utility?

From your calibration instructions:

Firstly perform the course voltage with the command python3 calvcourse.py Measure with an accurate multimeter the value of each battery cell relative to the battery negative. To improve the overall accuracy make sure that all the readings taken with the multimeter are done on the same range.

How do I input the actual reading from the voltmeter? When I send the command 'python3 calvcourse.py' it returns me to the cursor without any prompt to enter a value.

Thanks, George
