#23108 UART - Common ground

Posted by pa-1000 on 21 January 2012 - 04:47 PM in Netduino Plus 2 (and Netduino Plus 1)

I would like to communicate with a foreign device that is powered by a different power supply. The device is only sending data. The foreign device has 3 PINs (GND, TX, 5V). I think that I have to connect: 1. the GND foreign device to the GND of my netduino. So that they have a common ground. and 2. the TX foreign device to a Serial RX Pin from my netduino like PIN D2 for COM2. Is this correct? And is there a chance that something got damage? I use a 1k Ohm resistor in series with the TX -> RX cable. Is this necessary in case that the foreign microcontroller has 5V TTL Level? cheers

hi there, I'm also interested in using my netduino plus in my car. Does anyone use a netduino plus in his car? If yes is your netduino still a live? :mellow: cheers



#22598 Netduino Plus - Storing data

Posted by pa-1000 on 08 January 2012 - 08:19 PM in Netduino Plus 2 (and Netduino Plus 1)

thanks for your post. I thought that a database would be impossible =) ok maybe I can store some data temporary in a hashtable or something for analysing. your project sounds interesting, i will have a look



#22539 Netduino Plus - Storing data

Posted by pa-1000 on 06 January 2012 - 08:55 PM in Netduino Plus 2 (and Netduino Plus 1)

hi there, I have experience in developing c# but iam new in developing with .net the micro framework. I'm working on a little project where I collect data and store them on a sd card. I have a lot of measure data to store and analyze on the netduino. It should also be possible to download the data over ethernet. In a normal environment i would use a Database to store the data, are there any mini databases availabe in the micro framework? Or any other recommendations? What do you use for a storing and analysing data? thanks for hints
