This link also helped me a lot in moving forward with writing my own programs in I2C for my internship.
If your'e ever looking to develop your own library or driver, I couldn't find a better source to get started with.

Hello World, I'm working on a driver and the basic gist/setup of the method is :
public enum

cat = 0,
dog = 1

#59977 Analog Input Limits
Posted by woof_woof_bark_bark on 03 September 2014 - 11:21 AM in Netduino Plus 2 (and Netduino Plus 1)
I had a feeling that it wouldn't be possible. Thanks so much for the help!
Good luck and good thoughts,

#59973 Analog Input Limits
Posted by woof_woof_bark_bark on 02 September 2014 - 08:07 PM in Netduino Plus 2 (and Netduino Plus 1)
Hello all,
I've been playing with the analog input on my netduino, and I had been playing with it for quite a bit thinking that I had been using it wrong. Turns out... I was! When using a potentiometer to regulate the voltage into my analog input, I noticed that as I approached the upper end (higher voltages of my potentiometer) the value being printed from the .Read() of my analog input started to decline. I just learned today that that was due to using the 5 V pin on the board as my source and the highest value accurately registered through the .Read() was when the voltage was 3.3 V. I was curious if there was a way to allow for accurate measures of voltages higher than 3.3 volts via AnalogInputs (nothing necessarily too crazy... but how about the 5 volt pin?) I would appreciate any input on the subject.
Thanks for taking the time to read this.
Good luck and good thought,

PS. this is how I set up my code while using the 3.3 V pin as the source to my potentiometer providing me with an output that is between 0-1 (the voltage as a percent of 3.3 V). When I would use 5 V as the source and change AnalogReference_float to 5 as well; my output would be 0-1 (when at or below 3.3 V) and 1 - 0.6 (when voltage to the analog input pin was 3.3 V - 5 V) The biggest desire is to at least figure out - if possible - how to change the percentage ie: I would love to make the output a voltage as a percent of X as opposed to being locked into 3.3V.

Worked like a charm thank you!
#59560 Some serious issues with Netduino+2
Posted by woof_woof_bark_bark on 05 August 2014 - 11:25 AM in Netduino Plus 2 (and Netduino Plus 1)
Thanks for the reply, I don't know what I did between my multiple attempts to get the board working, but suddenly after plugging it one of the many times it just worked and now I got the firmware updated to 4.3.1.
Being new to this board, I do have one question. I'm working on this project that seems to be wrong, and after trying to put it on my board I found that when I went back to trying to but previously working programs on my board I get the error "An error has occurred. Please check your hardware." While reading the forums I thought the way to fix this would be to plug/unplug the netduino and then erase using MFDeploy. However, when I click erase after all this, nothing shows up that can be erased.
The only solution I've found to get the board working again is to reinstall the firmware, and I don't think that I should have to be doing that. Any Ideas what might be going on or what I might be doing wrong (besides writing a code that doesn't work)?
#59549 Some serious issues with Netduino+2
Posted by woof_woof_bark_bark on 04 August 2014 - 03:42 PM in Netduino Plus 2 (and Netduino Plus 1)
Hello all,
I just recently got my netduino in the mail Thursday, and I seem to have several issues with it. While trying to install a basic led flashing sequence, (I had had it installed earlier but tried to write another program that ended up wrong and scratched for the time being) I am prevented by the error "An error has occurred. Please check your hardware"
Like I said the board is brand new, and I don't know what could be wrong.
Things I've tried:
-Using MFDeploy, I tried looking at the device capabilities for the purpose of updating the firmware in hopes that might fix everything and sometimes if I try multiple times I get something that makes sense but most of the time I get pages of lines that read: "Failed allocation for 5 blocks, 60 bytes"
-I've also tried hitting erase in MFDeploy while trying to follow the steps to update the firmware and all I get is a constant stream of "Failed allocation for 5 blocks, 60 bytes"
-I've installed the installer for the latest firmware and my device doesn't show up.
- I've installed other programs the STDFU Tester application as instructed by the forums if the previous issue comes up, and that also seems to do nothing/doesn't recognize the device.
--------------------------------------------------------------------------------------------------------------------------\
My goal was to try and return this to factory settings as it was working for a period out of the box but the errors seem to be overwhelming and I'm trying to fix this quite quickly.
