Arduino based VDI!

The "Signagraph" seems to work very nicely. But ... I would suggest changing the name of your detector to something other than "A.S.S.".

I know it;-) But its more about fun! My friends laughed too;-) It means Advanced Survey Systems.....dont take it too serious;-) Things that wouldnt work are for the ***...things that work great are Advanced Survey Systems;-)....its a hobby!

Great stability, nice, simple code implementation. Its pretty crazy what you can nowadays achieve with few dollars of hardware and some code....

Thats amazing! Simple and accurate;-) Can you post how you connect the wires? I will test it on Tgsl. I have actually Darens version with an opamp working on my Tgsl.....but i want to test your version too on TGSL. I love simple solutions! Ok programming isnt simple for everyone;-). Thank you for sharing.

heres my Tgsl with Darens Version (Vdi wasnt finetuned in Video, actually its finetuned and is really accurate;-)):

Here is my setup. I have included the pinouts in the sketch comments too.

I got some inspiration from Daren's project and made some improvements to my own. Nothing besides an Arduino, 16 x 2 LCD and a handful of wires needed!! Plus the attached sketch. The only change needed to the IDX is to solder a pair of header pins and wires to U3 pins 1 & 14 and a ground wire from the IDX to the Arduino.

I added a fully functioning digital spectrum bargraph. Plus, with a concentric coil, accuracy is great.
Enjoy!

I saw the YouTube videos, (I am informed by YouTube when you post new videos!) really good and stable. Also when actually searching as well?

Good work, thanks for sharing.

I use classic 16pin connector. I have ordered two different I2C LCD's now. I will also do tests with the connectet LCD today ;-) Thank you guys! I will post pictures of the device when its finished and works without errors;-)

Hello,

i have upload the programm without errors. But the Dsplay shows only black cursors when i tune up the contrast. I have the LiquidCristal2IC library installed. I testet "LiquidCrystal Hello World" and it works perfect. Now i testet "LiquidCrystal2IC Hello world" and it shows only the black cursors after tune up contrast again. I think its the wrong Display. In the Sourcecode of the Arduino Vdi is mentioned to use LquidCrystal library not LiquidCrystal2IC library for other Displays. Can i change the Sourcecode that it works with my Display?

If all is wired correctly then maybe your LCD I2C device is at different I2C bus address. Use i2c-bus-scanner example to detect the I2C address. (googe: arduino i2c scanner),
For example see: http://todbot.com/blog/2009/11/29/i2...c-bus-scanner/
Each I2C device has factory designated address (sometimes you can change it with jumpers). You need to know yours. The code assumes most likely address (check the header with all the defines in the project), but your LCD can be configured differently. There is no standard for addresses.

Hallo

can you upload a Picture of your Setup
(reply click Go Advanced button)

did you use i2c connection from arduino to lcd or did you use the classic 16pin connector?

which Kind of Display you use
1602lcd (use library lyquid Crystal h)
or the Nokia display

Thats great Daren ;-) Now the programm works without errors! Thanks a lot Daren....and thanks a lot to Silver_Dollar too, you helped me so much. Yesterday I had a lot of frustrating hours, but i have learned a lot too. Now i will upload the programm to Arduino and test the Vdi that i have build the last days on the Tgsl;-)

Great Forum and great people here!

MenuSystem arduino library

Here is MenuSystem arduino library that is used by Arduino VDI. You install it by extracting it to you Arduino library directory. (For example: "C:\Program Files (x86)\Arduino\libraries" on 64 bit OS or to : "C:\Program Files\Arduino\libraries" on 32 bits OS). This will fix your problem.

MenuSystem.zip

Arduino VDI is using two libraries that don't come with Arduino (but you can find them on the web). Now both of them have been posted to this thread. Please use the posted versions.

[Prospekteur]

I had downloaded it. I have these errors:

"MenuSystem does not name a type"

"Encoder.cpp:102: error: `ms´ was not declared in this scope"

[Daren]

Did you download and installed LiquidCrystal_I2C.zip posted few posts above? The "ms" is MenusSystem defined in "menu.cpp".
