Dear All,
I have created an Arduino Dashboard that communicates with the arduino via the serial port. It takes design command from the arduino to display controls in the main window like button, combobox, checkbox, slider and graph. It also allows the plotting of values of a single source or all analog ports (6 for now). The source is written in Visual Basic and I am working on a Linux Port. Here some pictures, the source, the exe and a demo sketch can be found on my arduino pagehttp://www.mathias-wilhelm.de/arduino:

I hope you find it useful - enjoy

Ciao, Mathias

I downloaded your file (ArduinoDashboard v1.1.0), can't find any arduino demo sketch.

Salut,

the demo sketch is on the project page (as it is rather short) or here:

The project page also documents (work in progress) the syntax.

I agree that including the demo sketch in the download would be easier.

Havng copy-pasted the demo from your website, I got an error:
Code: [Select]

dashboard_demo:19: error: 'MsTimer2' has not been declared


I see

Code: [Select]
#include <MsTimer2.h>

so I guess this library from the playground needs to be installed. It would be useful to document any libraries that need to be installed.

The dashboard looks interesting, in particular the charting function (although that part seems to be undocumented as yet).

OK, it works. Scan ports is nice.

Pity that it shows an UNO board when I am using a Mega2560 :)

More seriously, in the example sketch. the port dropdown shows A0 to A5, three times. Itrs not clear why; also, while ports with something connected are read corectly, ports with nothing connected display a sine wave. It would be nice to see what the random noise on an unconnected port looks like.

Salut,

ok - the picture is a challenge ... will introduce a version query that includes the board and amend the picture  8)

I will check the port read - bad news: From the reference of the analogRead() function:
Quote
Note

If the analog input pin is not connected to anything, the value returned by analogRead() will fluctuate based on a number of factors (e.g. the values of the other analog inputs, how close your hand is to the board, etc.).

If you get near an unconnected analog pin with your finger you will see your quality as an antenna  ;)

With respect to the triple set of dropdowns I have to change the code to accept a reset of the dropdown entries.

Ciao, Mathias

@Mathias very nice demo.
