MintyBatterymonitor No on-screen battery icon

Post by kaning » Wed Mar 25, 2020 10:45 am

Hi all!

My setup is not really a pi zero build but i couldn´t find any other section taht this topic would fit.

I´ve built a Raspberry Pi 3 B+ on classic gameboy shell. i use Arduino Pro MIcro for the Controller.
For Power and Safe Shutdown i got a TinkerBoy PowerSwitch.
For Battery monitoring i got an ADS1015 and installed MintyBatteryMonitor.

So i installed both following GitHub and TinkerBoys instructions.
SafeShutdown works as it should. The MintyBatteryMonitor was installed sucessfully, no errors but on reboot no icon showed up. To check i grounded GPIO7 and indeed the PI turned of. When i ground GPIO19 nothing happens. I´ve read that you can do the same with "Select" (2 secs) but again nothing happens, never seen the battery icon. See connections below.

(nevermind the loose cable)

ADS1015
A0 connected to Battery+ with a 10k resistor
SDA to SDA on PI3
SCL to SCL on PI3
VDD and GRND to VDD and GRND on TinkerBoy PowerSwitch
I triple checked it. :D

So with this said i don´t know how i should debug this? Any tips?
ADS1015 Faulty?meh...
Should i start a fresh SD? I would cry because i dont even know what image i used eheh
Also thought of Trying OneForAll but i´m afraid the GPIO assigned for buttons bugs my current configuration, i dont use GPIO's for the controller. Can i remove the Key maping from OneForAll script? Thanks! in advance!!

have you enabled/turned on I2C in raspi-config.....

should be found in interfacing options....

running "sudo i2cdetect -y 1" at the command line should tell you if the ads is working. you should get like a grid of lines, with a "48" in the middle. i forget exactly where, like 40/b or something. it should look similar to this: https://learn.adafruit.com/adafruits-ra ... g-i2c-5-14

it shouldn't hurt to run the oneforall without using the gpio mapping either if you want to try that

Yes, confirmed.See below.
So does that mean that the battery monitoring is working?

Even if the TinkerBoy PowerSwitch have the S and P pins using those GPIOS?

I did infinitloop tip first so i guess that confirms it. I went in and set to enable anyway. Rebooted but still no baterry icon.

Could it be just a "graphical" issue? caused by the theme i'm using or something? Sorry about my ignorance eheh

yes - insofar as, the pi is recieving the reading from the ads over i2c

probably, but you can always update the one-for-all text config to point to other pins

it could actually. the icon can sometimes get lost off the screen.

you can enable the debug option in the mintybatterymonitor script, and that will write the voltage to the screen output, if it is reading it. then you can tweak the placement of the icon in there too -> MintyBatteryMonitor.py, "changeicon" method, change the X/Y coordinates in the PngView call

Hi again,

turning on the debug feature didn´t work, also tried messing with x,y but also no luck.

Ended improving my screen in process by tweaking a few settings and installed OneForAll script which worked but the icon is so small (i´m using 1280*960), a battle for another day. eheh

I also looked a way on how to remove MintyBatteryMonitor.py from the Pi but i got a permission denied when using
rm command. Is there other way to do this?

Wouldn't be too concerned about removing it, just put a '#' in front of the line in the rc.local file. So it's disabled.

But if you want to remove the directory for the minty battery monitor try this:

In the terminal:
rm -rf directory name (if that doesn't work use sudo in front)

To change the icon size you'll likely just need to edit the files on your computer and copy the larger icons over the existing icons.
