Getting started

Recommended Posts

Hi there,

I'm interested in getting started in using Tinkerforge.

What's a good simple system to start with and to be programmed in C++?

Any advice?

Thanks,

Erik

Do you have any idea for a project or specific interest?

 

Something easy to start with is always the weather stations. You can start with calling getters to get the measurements from the sensors and print then to the console. From there you can go anywhere (store data in a database, draw graphs, etc).

thanks borg,

I would like to start with a very simple application programmed in C++ and using the Tinkerforge Hardware and Software.

What are the requirements in terms of Hardware and Software?

In terms of software you need to download the Brick Daemon, Brick Viewer and C API Bindings. You can get all of them here: https://www.tinkerforge.com/en/doc/Downloads.html

 

To get started with the C Bindings you can take a look here: https://www.tinkerforge.com/en/doc/Software/API_Bindings_C.html

 

In terms of hardware it obviously depends what you want to do. The absolute minimum that does something useful and is easy to understand would probably be a Master Brick together with a Temperature Bricklet 2.0.

 

Hardware wise you need:

 

* Mini USB cable

* Master Brick

* Bricklet cable (7p-10p)

* Temperature Bricklet 2.0

 

Master Brick: https://www.tinkerforge.com/en/shop/bricks/master-brick.html

Temperature Bricklet 2.0: https://www.tinkerforge.com/en/shop/bricklets/sensors/temperature-v2-bricklet.html

 

You can pick the suitable cables as options in the shop.

 

To get started, you connect the Bricklet to the Brick with the Bricklet cable and the Brick to your PC with the USB cable. Now you can view the temperature in Brick Viewer and use the C Bindings to read out the temperature in C++.

Thanks borg,

I'll have a look at these items.

If we would like to integrate also a Wi-fi module on this system, what would be the extra requirements?

Kind regards,

You need an additional WIFI Extension 2.0 and a USB Power Supply.

Hi borg,

 

thanks for the feedback.

I got the parts and connected them together.

 

In the Brick viewer I can see the live Temperature evolution over the time.

 

I'm new to C++, how can I use the binding functions that you mentioned?

Do I have to use the Makefile?

I can compile the code but there's an error when I try to link (build) it.

 

thanks in advance,

Erik

You don't have to use a Makefile.

 

Which operating system and which compiler/IDE do you use?

thanks borg,

 

I followed the instructions that you suggested and it's working now.

I've created a project folder with the files below:

1) example_project/

-> ip_connection.cpp

-> ip_connection.h

-> brick_master.cpp

-> brick_master.h

-> bricklet_temperature_v2.cpp

-> bricklet_temperature_v2.h

-> example_callback.cpp

 

2) update #define UID with the UIDs from the brick and the bricklet.

 

3) from cmd:

gcc -o example.exe *.cpp -lws2_32 -ladvapi32

 

Any ideas on the next steps?

 

kind regards,

Erik
