New Grove Pi User

Hello..

I'm a new Grove Pi user--I'm trying to set up the DHT sensor and a barometer... the code is compiling, but I'm unable to open the serial port to read the data. I have the Arduino IDE set to Uno... could this be the problem? What board should I select for the Grove Pi? If not, could someone lend some insight as to why I cannot open the serial port..

Thanks!

do you have a link to the grove PI?
I am unfamiliar with that device.

Hi,
i have the same problem as the threadstarter and since he doesn't answer i try to provide all the information :slight_smile:

So the GrovePi ( GrovePi Internet of Things Robot Kit ) is a shield for the Pi that aims to provide easy access to the Grove Sensor System from Seeed Studio ( http://www.seeedstudio.com/ ) which are ment for Arduino (or their own Arduino Clones Seeeduino, for example the Lotus http://www.seeedstudio.com/wiki/Seeeduino_Lotus_v1.0 )

As far as i could find out it has an ATMega328.
I also found this forum post on the manufacturer's forum about this:

In there they refer to the Firmware Update Process which is described here: Updating the Firmware - Dexter Industries
Here is an .ino file which seems to be the firmware on GitHub: https://github.com/DexterInd/GrovePi/blob/master/Firmware/Source/v1.1/grove_pi_v1_1/grove_pi_v1_1.ino

I think this should help someone who has a bit experience (or at least more then me :slight_smile: ).

Here are some additional links:

http://www.framboise314.fr/docs/The-MagPi-issue-23-en.pdf has an article about the GrovePi

I hope i could help!
If you need more information, or if i should try something, i'm happy to help.

Bye

On an arduino the DHT sensors don't even need a separate shield. But does arduino code even run on a pi?

The Grove Pi has it's own forum. It might be slightly more useful to post your question there, as the people there will have some idea what the *!£% you're talking about.
