Having SAM-BA issues while reflashing N+

27 November 2012 - 05:07 AM

Hello, I have a windows 8 pc that I'm trying to setup to play with my N+, everything worked fine with the last project (on Win7) and now decided to do another project and not getting anywhere. First I couldn't load any projects on it, so decided I'd reflash it. I did the 3V3 + copper pin, and it came back as GPS camera.. So far so good. Loaded SAM-BA, started it up, selected the chip and the com port but I get an error while trying to connect. The error is something like: Error h_handle returned zero while executing "TCL_Open $target(connection)(" invoked from within "if{$::argc >= 2}{... Is SAM-BA not going to work with Win 8?

Netduino + Thermocouple

26 November 2012 - 08:24 PM

Quick question to you guys, I wanted to monitor grill temperature remotely, and took one of the probes from my grill thermostat and used a meter to see the resistance change on it. Is there a way I can use that in my AI on netduino plus? or do I really need to get one of those thermocouple amplifiers? The rest of the plan is pretty simple, I have one of those wireless shields (forgot the name) and an app on my computer that would get the info and write it into spreadsheet which is saved to cloud and reported on my phone. I can also update parameters on the spreadsheet and have the app on my computer adjust the speed of fan. How does that sound?

Stable communication between PC and netduino+

06 February 2012 - 12:18 AM

Hello, I've been tinkering for a while now with my netduino+ and since I'm really not an electronics wiz I maybe missing a much simpler approach then I ended up with. In the end, all I really want to do is communicate with my N+ from my pc, wirelessly. It maybe that I need 2 netduinos, or just one. So far, I've played around with using webserver to communicate with it, and through the ethernet port, I could slap wireless shield on it and use it, but I have found the webserver approach not very stable for very precise control. For example I want to send commands to it a few times per second, webserver does work but occasionally will stall. What are other approaches? What is the best approach for communications like this? I do want around 20-40' of wireless connectivity too. Thanks, Viktor.

can't connect to my netduino anymore

04 February 2012 - 03:14 AM

Hello, I need someone's help on this. I tried updating to the 4.2 rc4 firmware and ran into an issue. I first jumpered the 3.3v to the little copper tab by port 0, then i tried connecting the device and windows said it couldn't connect to it and eventually figured out that it was a gps camera. Well, I was able to use SAM-BA to load the tinybootloader unto it, but now i am trying to get it to show up in mfdeploy and it only shows up under serial connections com3, but of course can't ping/erase/upload to it. What else can i do to get the card back into operation? Thanks, Viktor.
