It got me thinking ...
We should have an application that is PC based, that talks to a netduino through IP. The PC version would display the difference (3 columns, one for the selected function PC result, one for the Netduino result and one for the differences) for input many values for a selected function (have a combobox with all the available function) (2 more columns for the time it took ?)
The PC application would poll the netduino for a series of results from a given function and a given series of input values, and then display them on screen.
This would allow to show the valid ranges of some functions (we do that in physics) and the cost of using them (FFT you need something fast no ?). It would also allow the library coders see the results of their implementation on the spot

Normal Netduino for me ! Will need the Netduino plus to test it live with the webserver app that Mario put on the forums that I need to modify for this purpose ![]() #12483 Best way to convert string to number
using System;
ActualReading = Convert.ToUInt16(sActualReading);
#11521 Recommend a scope or PC card for working with Netduino?
Hesitating between these two :
Saleae or
DSO 2090 USB PC USB Oscilloscope 40MHz 100MSa/s 2CH
Picoscope are way out of my budget (which is between 150 and 250, tax and shipping included)
#13234 PanAndTilt
I thought we should never connect motors directly to the netduinos because of spikes ... just a thought !
#13238 PanAndTilt
No thanks needed, I'm much of a newbie too so ... just saw the diagram and got shivers ... lol #12580 High Speed Photography
Hey, I bought a co-processor for one of those to make my galaxy creation simulation work in a week instead of a month ![]() I'll have to learn about those ![]() Yeap, that is me, simply learning .net in an interesting way (.net in all forms, normal, phone and MF, cool and having fun) This is the goal of this experiment. Find out what works and what is missing, all for the ease of programming whatever we get our hands on ![]() I'm looking at a 3D Printer right now and it is because I played with a netduino that I might have on in a few months ![]() It is not a problem of our lack of knowledge about what to use when ... it is a question of finding out how we can adapt our tools to help even more ![]() I Love This Community (ILTC) #12268 High Speed Photography
30fps is about 33ms ...
do you have access to the ccd through i2c or serial ?
what is the throuhgput available from the netduino compatible camera ? links please
![]() #13204 Analog input varying too much on temp sensor (LM335A)
I have been trying to get stable data from a LM335A Temperature sensor and I do get a variation of 3 to 4 out of 1023. You say this is normal ? When I look at the oscilloscope data, it is quite stable (better using 10 pF capacitor) but still a variance of 3 to 4 ... you say this is normal ? The variation on the oscilloscope is does not even equate 2 out of 1023 so why more variance ? A variance of 3 would make sense since the LM335A Temperature sensor is 1C accuracy which equates to 3 out of 1023, therefore a variance of 3 would be exactly the accuracy of the sensor. Am I making sense here ? But the oscilloscope seems to be more stable than what the Analog pin gives out ... why would that be ? The voltage to be read is more stable than the values obtained by the analog pin reading ... why ? I use 3.3V with a 300 Ohm resistor and a 10 pF capacitor. I did see that I have 3.250 instead of 3.3 when I put the oscilloscope on the power thread on the breadboard ... why I do not know ... shouldn't be 3.3 ? (was using USB power) #12696 Any help on a ParallelIn SerialOut Bitshifter?
Hi Stefan,
I looked at your code for bitshifter ... cool

LoL me and my short term memory ... #13169 Netduino/Android - is it possible
Thanks, I'll look into it
![]() #13149 Netduino/Android - is it possible
Can you point at code 'cause I would like to know how to do just that ![]() ![]() #12335 Making the Netduino a little bit closer to a RTOS device
That made me think about how we used to do sampling of brainwaves for consciousness detection under anaesthesia. First capture data and nothing else, then massage it (cumulate to get base wave, filter the 60hz that is everywhere, etc...). Since it is blocking, does it gives you full access to the mcu ? for only one process : capture data. That would be perfect. So, correct me if I'm wrong, native code would allow you to stop everything else (gc included?) to capture clean data (maximum time allowed ?) and then back to managed code for ease of programming and analysis. I want one ![]() That would be an interesting tutorial for advanced users ![]() I'll check, thanks for posting ![]() #12336 MotorShield driver
Girls ? Where ? Cool, I'll want one when budget will allow ![]() I vote for this one, you can easily read the purpose of the code ![]() I vote for not adding all those overloads ... no overlords please ![]() #13148 Little Tutorial on the NetduinoMini and XBee Connections
Thanks
![]() #12465 Speaker class and Netduino Keyboard
You have cool friends
![]() #12582 Happy Birthday boobytrap
Forgot to say, VERY COOL PROJECT !
A definite must have on a tutorial site
![]() #12581 Happy Birthday boobytrap
How many netduino minis does that make ? #12236 C# Coding standards
I'll check that one too ! I want to build a C# guidelines for .net MF code ![]() #12233 C# Coding standards
Will be looking at it to add some Coding Standards to my Netduino Tutorial ![]() #12244 C# Coding standards
Wow ! I was doing it all wrong LOL ! I was mixing up both System and Apps Hungarian, and prefering the Apps one but tried to continue on the System one too and hating it ... been off programming for 7 years ... thanks, now I know what to do, keep the good and throw the bad and ugly system hungarian from my habits ![]() A big thanks for the article you point at ! Boy do I love it here, I learn so much ! #12262 C# Coding standards
Got that right lol #12622 NetduinoPlus Silverlight Server (preview)
Got it Thanks !
#12924 Charlieplexing: Now uses the TristatePort class
Now I understand why the tristate ports exist in the first place
