How to interface Arduino with the Raspberry Pi? Can i interface multiple Arduino boards with Raspberry simultaneously ?
There are a few ways of doing that. The way I’m doing it is via Ethernet / WiFi. I setup the pi as a web/mysql server and send the information from the Ardunios via the network. If you need more help let me know I’ll post a few links.
Thank you Please post some. I really need to start the work.
@captainpc how are they connecting mega 2560 with the raspberry in this food computer?
The Arduino is connected to the Pi trough the USB/serial port
Hi @martinvgb could you please post a link to the documentation that shows how to connect the Rpi to the mega 2560 via USB? I checked https://github.com/openaginitiative and found some documentation but couldn’t find anything explaining how to connect the two together. I know how to do it via Ethernet but USB might be better for this project…
I found the following link with instructions on connecting Ardunio to Pi via USB cable and it’s working well.
The only thing missing from this guide is the python-serial component which I installed on my pi using
sudo apt-get install python-serial
One more thing… When copying/pasting the Ardunio code make sure to type in
the quote marks manually where the “Hello Pi” is otherwise you may get error when uploading the code.
Hope this helps.
I am not sure I understand the question.
The interfacing is build in the Arduino and PI program ( precompiles as an IMG)
You “just” need to
- Load the arudino program
- copy the IMG of the OS for the i PI on a SD card and boot with it
- connect the Arduino to the PI using the USB cable
