Pushbutton Operation

• Short pressure: start trip (green LD1) ⇄ stop trip (red LD1)
• Double click: reset trip (blue LD1)
• Long pressure: LEDs enabled (white LD1) ⇄ LEDs disabled (orange LD1)
• Hold button while reset (connect to battery): restore factory settings (magenta LD1)

Command-Line Interface

Manual without frames

Terminal Emulator

You can use the command-line interface CLI via USB CDC or Bluetooth LE vSP. You need an application for the PC or an app for the smartphone.

Terminal emulator apps for smartphones (Bluetooth)

The BLE vSP profile is proprietary, there is no standard serial communication profile:

• Android Smartphones Laird Toolkit, Serial (vSP)
• iOS Laird Toolkit, Serial

After a successful connection the LED LD16 is on (blue).

Terminal emulator applications for PCs

You have to connect the Velo Bling-Bling with an USB cable to the PC:

• PuTTY (Windows and Linux)
• Tera Term (Windows)
• Realterm (Windows)
• minicom (Linux)

You have to install a driver for Windows. The device name is Virtual Com Port, the appropriate INF file (Setup Information file) is fsl_ucwxp.inf.

After the connector is plugged in, LED LD14 goes on (green or yellow). Additionally a LED from LD1 to LD13 goes on, these LEDs show the battery level, LD1 (red) is lowest, LD13 (green) is highest (battery fully charged). If you push the ESC or the '>' key now, the LEDs go off and similar text is showed:

Euler Wheel 32, Velo Bling Bling

CLI>  

Basic Configuration

Hier ein paar Beispiele, wie man das Bling-Bling konfiguriert. Es müssen nur die fett geschriebenen Zeichen eingegeben werden.

Beispiel um den Radumfang einzustellen (Eingabe in Meter, alle Einheiten sind SI):

CLI> set circumference 2.130

Oder in Kurzschreibweise:

CLI> set circ 2.130

Vorderrad auswählen

CLI> set wheel front

Soll die Konfiguration dauerhaft abgespeichert werden, d.h. auch nach einem Akkuwechsel oder wenn der Akku voll entladen wurde.:

CLI> save

Die obere Anzeige wird upper die untere lower genannt. Den Teil zwischen upper und lower nenne ich bling. Im bling Teil werden die Bilder wiederholt, wenn eine Anzeige ausgeschaltet ist (blank), dann wird dort auch das Bling-Muster wiederholt. Will man in der Anzeige den String (Text) Hallo Velo! ausgeben, so geht man folgendermassen vor (bitte beachten! für Leerzeichen gibt man _ ein):

CLI> set string lower Hallo_Velo!
CLI> set lower string

Images

Man kann auch Bilder mit der Escape-Sequenz \i<nn> in den String einfügen, z.B. die Schweizer Flagge mit \i00. Weitere Escape-Sequenzen:

 *     _      Space
 *     \_     _
 *     \\     \
 *     \i<nn> image number 00..49
 *     \f<nn> font         00..04
 *     \c<nn> color 00..07 
 *     \s<nn> space in columns

Die Farbe des Strings setzt man mit:

CLI> set color lower green

Farben:

red|green|yellow|blue|magenta|cyan|white
rd|gn|yl|bl|ma|cy|wt

Momentan sind nur wenige Bilder abgespeichert (hauptsächlich Nationalflaggen). Insgesamt hat es im Speicher Platz für 50 Bilder. Bilder können auch heraufgeladen werden. Beispiel um Bild 21 auf der unteren Anzeige auszugeben:

CLI> set image lower 21
CLI> set lower image

Hier die Liste der momentan verfügbaren Bilder:

 
0:  Switzerland
1:  Germany
2:  Austria
3:  Italy
4:  France
5:  Belgium
6:  Spain
10: heart
11: snow
20: Germany spyr.ch Switzerland
21: countries Austria Italy France Belgium
22: countries Switzerland Italy France Germany 
23: countries Germany Switzerland Italy
24: veloblingbling

Will man die Schweizer Flagge als Bling ausgeben:

CLI> set bling img
CLI> set image bling 0

Die Seite (surface) mit dem Drucktaster heisst top, die andere bottom. Die Befehle wie set lower image beziehen sich auf die augenblicklich eingestellte Seite. Die Seite wählt man aus mit:

CLI> set surface bottom

Die wichtigsten Konfigurationen (die Infos beziehen sich auf die eingestellt Seite, in diesem Beispiel auf top) ausgeben:

CLI> show all

Es sind 20 Zeichen in 5x12, 14 Zeichen in 7x12, 12 Zeichen in 8x12 und 8 Zeichen in 12x16 Font darstellbar. Die verfügbaren Fonts sind 5x12 (0), 6x8 (1), 7x12 (2), 7x12b (3), 8x12 (4) und 12x16 (5). Der Default-Font ist 7x12b. Font ist innerhalb des Strings mit \f<nn> änderbar, z.B. \i00 für den kleinsten Font.

Scripts

Very simple script interpreter. Every line is interpreted by CLI except lines beginning with : (colon) or ; (semicolon). After reading a semicolon the script restarts from the beginning. A line has to be <= 80 chars long.

The script buffer is 800 bytes and shares the same memory for the images (dotmatrix). That means one buffer has room for about 50 command lines. If that is not enough then you can start another script buffer within the script.

Special Commands

:wait n

waits n seconds

:exit

aborts script

;

script end, restart script from beginning

Sample

CLI> set script 40
set string upper Hallo
set string lower Velo
set upper string
set lower string
:wait 10
set upper speed
set lower trip
:wait 10
;
CLI> show script 40
set string upper Hallo
set string lower Velo
set upper string
set lower string
:wait 10
set upper speed
set lower trip
:wait 10
;
CLI> script start 40
CLI> script stop
script stopped

Terminology

Display

In this example the upper display shows the current speed and the lower display the string veloblingbling. Each side has its own independent upper an lower display (see section Surface below).

Between these two displays there is another display called bling. If the upper or lower display is blank and bling display is not blank, the bling image/string is showed instead. The bling image is repeated till the end of the rotation, see the rear wheel in the video: the upper display shows the trip distance, the bling display shows the repeated image with the Swiss, German, French, and Italian flags. After each rotation the image is turned counterclockwise 4 pixels.

Surface

The Velo Bling-Bling side with the pushbutton is called top surface (usually the left side), the other side bottom surface.

Mode

The displays can show static or dynamic info. Strings or images are static, cyclocomputer values are dynamic. Bling displays can show only static info.

Image

Images have a height of 16 pixels (the number of LEDs) and a maximum length of 100 pixels. The LEDs can display 8 different colors.

String

Trip
