Now a sub that makes a battery/level graph in a box by providing 4 parameters
the line number the character number the size of bar in characters and the number
of blocks in the bar the last paramete ...

I am working on having a box around the bar like we see on battery meters
as soon as its working correctly so the size of the graph can be set then
just the number of steps is then told to be placed ...

I wanted to draw bar graphs and a battery level indicator on 128 x 64 and 240 x 64
displays but wanted a simple versatile code conservative way to do it I made some
bit map files converted them to b ...

Have been there but still not working have not the time to work on it for now
will get back to it in the future.

Having programmed Nextion displays to directly control my inverters I can recommend looking into the reparse
mode where you control the serial of the display it opens great opportunity in data trans ...

I worked with 48v systems every day in my job as did thousands of others all around the world
there were even 100volts on the earlier equipment the 48v positive battery and smaller 48v negative
one ...

Has anyone the library for the RA8835/SED1335 as the links from trexis_5
are no longer working and I have 4 320x240 displays that I would like
to get working primarily as text displays with bascom t ...

I have two homes with solar they have 48 volt batteries the solar panels are nominal 24 volts
they are is series with sets of 3 so nominal 72 volt but get to 95 volts open circuit the charge

Now some code.
This reads the responses on the rs485 that the Junctek display requests from the 140F
so is passive , it removes the displays request leaving the returned data it only uses the
m ...

Switching off the rs485 is even more odd when you have their display attached as it stops working.
They have the same functionality and accuracy as another major brand (there stuff is painted blue) ...

The JUNCTEK KGF140F , KL140F are battery monitors that provide
Current , Voltage , Ampere Hours , Watt Hours , Temperature , Over Current , Over Voltage , Over power
Under Voltage , Battery internal ...

Your clock faces are really good.

So far I have made 3 electronic clocks in my lifetime one is with bascom
is in the examples , one was last millennium with glass display tubes when led's
were n ...

long time ago i worked (engineered) in telephone exchanges with 48V or 60V batteries i know that you should be very, very careful. one colleague from the battery department let a metal tool fall on ...

Note the wires from the split core can be fairly long if run as a twisted pair as
the impedance is low as the burden resistor is about 30 ohms.
Arduino has already code for them so you will be able ...

The PZEM-004T is a cheap way to measure power has a isolated serial port , split core current transformer option.
Interfacing to an AVR would be simple and would be great to have a Bascom library for ...
