AnalogInput Read() LOCKS UP NetDuino

31 August 2010 - 07:17 PM

Just trying to read some analog values, and my NetDuino is locking up the debugger when it hits the Pot0.Read() line.... This is very disturbing as I've had to HARD reset it several times by using MFDeploy to make it work again. Any ideas?

I've bolded the line that it crashes on when it gets to the code.... This is with 3.3v hooked to aref. Is my netduino broken?



            AnalogInput Pot0 = new AnalogInput(Pins.GPIO_PIN_A1);
            AnalogInput Pot1 = new AnalogInput(Pins.GPIO_PIN_A0);

            while (true)
            {
                [b]int Pod0val = Pot0.Read();[/b]
                int Pod1val = Pot1.Read();
                Thread.Sleep(50);
             }


5mm Color Cycling LED

27 August 2010 - 04:53 PM

I know a lot of people like me enjoy seeing what components do, so since I just got my order of slow color cycling 5mm LEDs I hooked them up to 5V with a 330 ohm resistor and this was the result: http://www.youtube.c...=1&hl=en_US

Best Hobby Oscilloscope

26 August 2010 - 04:05 PM

Ok, being an electronics newbie I know I'm posting tons of questions on here. Everyone has been really nice though, so I hope that continues! :-) I'm looking to get an oscilloscope to use with my netduino projects to analyze when issues come up. I've seen the PC Sound card based ones, and those seem like they're not really the best idea. I've also seen some scopes like this: http://cgi.ebay.com/...I_Oscilloscopes and this: http://cgi.ebay.com/...I_Oscilloscopes Any suggestions? I'm looking for something small, and easy to move around since I do my work in various parts of the house where I can get some space. :-)

Soldering Temperature for IC's, etc...

25 August 2010 - 04:02 PM

I've got a weller Soldering Iron which goes from 350 to 800 degrees farenheight (Weller WES51). It works great, but I wonder sometimes if I'm making it too hot. Before I knew what the know did (duh, it says degrees F x 10) I used to try it around 500 degrees, but it didn't seem to get hot enough to get the solder to flow within about 4/5 seconds and I was concerned about the components. When I kick it up to 600 or 650 it works GREAT, but things get really hot. I especially worry though when I'm soldering things like Capacitors and Diodes or transistors. How long does it take before these items get damaged by the heat? Is this the proper heat to use? Too hot? Not hot enough? I know some of you electronics types know this. :-) Thanks! Jeff
