Gnuplot Script for Wheellog 1.0.2
By Chriull
wheellog 1.0.2.dem
Tested/developed with gnuplot 5.2.5 https://sourceforge.net/projects/gnuplot/files/gnuplot/5.2.5/
Version 1.0.2 for wheellog data files
Usage (Windows):
[path-to-gnuplot-executable]\gnuplot.exe -c [path-to-script-file]\wheellog 1.0.2.dem [path-to-wheellog-data-file]\[data-file-name].csv [Options]
!Attention - options are case sensitive!
Options:
log|i-v
log: "normal" diagram (datafile values over time)
" i-v": (Current over Speed Diagramm), log is default
lim
Show limits (time to overlean, percentage, U Battery 0, etc), requires profiles (internal battery resistance, coil resistance and kv to be known and set)
p[number]
Profile Number for Limits, 1 is default
norm
Normalize i-v diagramm. Speed and Current Values are "normalized" relative to the "internal" battery voltage (U0), so there is one fixed current over speed limit.
Sets the option lim, profile values of the wheel have to be known and set.
Axis values are not valid anymore!
screen|out
Write file or show on screen"'
Output filenames will be the original filename with the ending .csv.png for "normal" logs, .csv.i-v.png for current over speed diagrams and .csv.i-v.n.png for normalized i-v diagrams.
! Attention: files will be overwritten without warning !
Customization of the script file:
This version depends on the column header of the .csv files. If one has still old whellog date files wihtout header, one has to insert a corresponding header line.
For the different datafile versions in regard to temperature the script tests the columns "system_temperature", "battery_temperature" and "temperature" and uses the first found with values.
Date has to be in first column, time in the second.
The "log" diagram can be customized with the _plot_param array
Show: 1 show this value or 0 hide it
Color: one of gnuplots internal colornames or #RRGGBB (explicit Red Green Blue Triple in hexadecimal
Width: Line Width
Axis: 1 - Values according to left hand y-axis, 2 - Values according to right hand side y-axis
Name: Name for legend
Profiles:
n_profiles ... With this variable the number of profiles is specified (Profile 1..n_profiles are valid and have to be set)
_wheeltype[profile_number] ... Name of wheel
_R_i_battery[profile_number] ... internal resistance of Battery
_R_coil[profile_number] ... resistance of motor coil
_kv[profile_number] ... Motor constant kv in V/km/h

Gnuplot Current over Speed Script for wheellog data
By Chriull
Gnuplot Current over Speed Script for wheellog data.
(see http://forum.electricunicycle.org/topic/7855-anatomy-of-an-overlean/ for more details about this kind of graphs)
Usage (Windows):
[path-to-gnuplot-executable]\gnuplot.exe -c "[path-to-script-file]\wheellog I-v.dem" [path-to-wheellog-data-file]\[data-file-name].csv
Customization of the script file:
Wheellog data is saved in a csv file with different columns. As far as i know this columns change either one activated GPS logging or not. Also for different wheel brands and types could be different columns.
This columns have to be entered in the corresponding lines in wheellog.dem:
###########################
#
# Datafile columns
#
c_current = 8
c_voltage = 7
c_speed = 6
Wheel specific constants are by now entered for the KS16C (obtained by wheellog data of an overlean in the above linked topic) - for other wheels they have to be changed acordingly.

Gotway Android non-social app
By Marty Backe
This is the older non-social Gotway Android app that will work with all versions of the ACM, MSuper V3, Monster, and MCM, as of 12Jul2017.
I personally use this version to control my ACM V2 and V2s+, MSuper V3 and V3s+, Mten3, and Monster. I have also connected to an MCM and configured it.
Works with the Tesla too.
NOTE: Do not use the Download to the right to download the 'wrong' file. Use the link below to download the com.example.bluetooth.le-2.apk file.

Wheellog to GPX
By Chriull
This ZIP contains the wheellog.jar file and the source code (wheellog.java).
Wheellog.jar extracts the GPS Data from the wheellog logfiles to an .gpx file.
Usage: java -jar wheellog.jar [Options] [Input-Filename(s) (with wildcards)]
Options:
-y .... Overwrite Output File
The output filename will be the first input filename with the extension changed to .gpx
GPS Data from each input file will be put in an own track of the GPX file named as the input file.
The wheellog file has to have a header column ( imho older versions did not write this columnheaders). The columns "longitude" and "latidute" are used to create the gpx file. Date is assumed to be the first column, time the second.
Here an example of daily gpx files created and shown in google earth. For one of these days i changed the color to different shades of red:
(google maps does not support gpx files with more the 5MB!)
if one has the data files in different subdirectories (by day) starting with 201?_ one can use a batch file like:
TODO:
wheelog multiplies the gps entries, since the wheel data has a higher sampling frequency. Found out that gpx size can be reduced to ~1/5 by eleminating the unnecessary entries. (Until i changed this gpstrackeditor.com is a nice tool for this...)

Gnuplot 5.0 script for wheellog data
By Chriull
Gnuplot 5.0 script for wheellog data.
Usage (Windows):
[path-to-gnuplot-executable]\gnuplot.exe -c [path-to-script-file]\wheellog.dem [path-to-wheellog-data-file]\[data-file-name].csv
Customization of the script file:
Wheellog data is saved in a csv file with different columns. As far as i know this columns change either one activated GPS logging or not. Also for different wheel brands and types could be different columns.
This columns have to be entered in the corresponding lines in wheellog.dem
This is either the p1axis1 or p1axis2 variable (p1axis1 shows this column on the left axis, p1axis2 on the right axis.)
The corresponding title can be set with p1a[1|2]title. (Attention - space is a seperator and can by this not used within a title!)
The next variables are p1a[1|2]factor, if some fixed factor division is needed/wanted.
Color can be choosen with df_colors[1|2]. The last variables df_with[1|2] set the line width.
This sample script works for KS16[B|C|S] with GPS logging activated. For other wheels and depending on GPS logging the column numbers in p1axis[1|2] have to be adopted according to the used csv file format.

King Song Android App (APK) 2015-10-07
By John Eucist
This is for units manufactured after September 2015. Apparently you can't get your ISN via the app with this Android APK (you can with iOS version). I've discovered that your "ISN" (in order to get your "auth code" from King Song) is your Bluetooth MAC address (6 groups of two hexadecimal digits) but "reversed". For example "12 34 56 78 90 AB" becomes "AB 90 78 56 34 12".
EDIT: Note that your ISN is not your auth code. It's what you need to give King Song in order to get your auth code.
EDIT2: It has come to my attention that with the newer firmware (I had an older version) you *can* get the ISN via the app.
