I hope you all will be absolutely fine and having fun. NI myRIO is an amazing processing tool that has a very high processing speed as compared to other microcontroller e.
Arduino vs. Raspberry Pi
Arduino, raspberry pi, gellilio etc. So, it can be used for the real time projects where there is need to respond very quickly according to the assigned tasks. It has different models. This module has a built-in Wifi as well as USB cable supported. The device has its own IP address which helps while configuring it.
If we want tmo connect it over internet then the IP address changes to access the device online. It operates on MHz. The tutorials basically focuses on controlling an LED on Front Panel with the help of the on board button on the device.
myRIO: FPGA SPI Communications
I hope you enjoyed this first project with myRIO. You should also have a look at these LabView Projects. If you find any sort of problem, you can ask in comments anytime without even feeling any kind of hesitation. I will try my level best to solve your issues in a better way, if possible.
I am a programmer since before that I just search things, make small projects and now I am sharing my knowledge through this platform. I also work as a freelancer and did many projects related to programming and electrical circuitry.Pages: . But I am trying to replace it with an arduino. I have never used an arduino before and I ma not sure how much of changes it will introduce to my current setup.
My setup supported two input signals and a ground signal analog from which it is sampled and digitized. I am hoping to achieve a sampling rate of Hz if possible with arduino as a DAQ. What are the voltages of the signals and what resolution do you require? So the output of my breadboard would be analog signals in the range of millivolts to like 5volts.
ECG signals are fairly small so even after amplifying it I would need something able to handle signals in mV ranges accurately. I was setting it to acquire and display 20 second of data for each person.
After 20 seconds, I pause the program, capture the signal plots and their excel values from labview, before I run the program again to take another set of 20 seconds data. Higher the sampling rate the better I guess. What is the max I can get from an arduino uno? Does it acquire and send data to labview close enough to real time?
In the labview side I further filter the signals that come through the DAQ to remove noise and improve. My current labview model has a DAQ assistant connected to bandpass and bandstop filters. I am trying to see if i can still use that labview model with minimal changes and connect an arduino to work as DAQ. I repeat: what resolution. You have 10 bits on the arduino.
At 5 V max, with steps, you have about 5mV per bit. I dont have an exact value for resolution requirements but I will say something close to the ones I achieved with an NI DAQ would be enough. I see that its resolution was around 1.
So based on your answer I will only be able to get a resolution of 5mv, making my signal less accurate than before using an arduino? Is there any way to improve this resolution? Not if your maximum signal is 5 V. You would need an external ADC. There is an internal analog reference voltage of 1. If that helps for smaller signals.
Thanks for the feedback. I checked and found I can make do with the resolution of an arduino and also I can change the output voltage levels so as to achieve better resolution.
I am new to arduino and quite confused as to where to start. I have an arduino uno with a usb cable. My aim is to replace the DAQ with an arduino in my current setup. To learn this as quick s possible, what would be a basic tutorial for arduinos and its usage with labview as a DAQ replacement?
Though this is a simple setup for now, I also plan to connect a go pro camera to it and synchronize it to start analog signal recording and camera recording at the same time. Hi anyone have any feedback on my above question? Currently after testing the arduino for basic programs I am trying to design and labview model to use the arduino as a DAQ. I am hoping someone can suggest some basic tutorial that I can refer to to help me with this.
The arduino will be used to get sample analog voltages to output a digital value that can be plot and stored in the computer. Start Here It's easy and straightforward.

Littman, Michael G. However, the existing tools, supplied by National Instruments, are inadequate for developing control applications. This report details an approach used to implement the control system directly onto the FPGA, allowing for high-speed control, while sending diagnostic information back through the processor to gather measurements from the controlled system.
These experiments provided interesting control problems that required two dependent control loops. The controller was implemented both at the processor and FPGA level. For control applications where the time step is on the order of 1ms, implementing both loops on the processor produced adequate results.
Moving the controller to the FPGA did not improve the controller at this timescale. Finally, this report concludes with a section detailing how one could include a myRIO into future projects.
It includes diagrams and suggested structures for implementing controllers on the FPGA with minimum hassle. It also looks at the challenges that come with working with the myRIO system and what limitations exist with the device. Mechanical and Aerospace Engineering, Request a copy.This article will show how to utilise what we just learned to interface with the real world.
It is recommended that you use a 3. As we will see in later articles, when it comes to reading it will be able to go further. Then we need to calculate a value for our current-limiting resistor that will be connected in series between the LED and the Digital Line.
There is a lot of fantastic material on the topic available online and we will not dwell too much into the theory. Looking at the wiring schematic Figure 1 we can see that the Resistance, R can be found as follows:. Where Vs is the source voltage, in our case 3. Vf is the forward voltage of an LED, usually specified in the datasheet, in our case 1. Finally i is the current needed to drive the LED to full brightness.
This value can also be found in most datasheets and usually is around mA. Substituting these numbers into our equation we find that the recommended series resistor value to limit the current flowing through the LED is between 60 and 95 Ohms. In the time of writing this article, the closest resistor value I was able to find was Ohms and it worked fine. Saying that, with resistances over 1 KOhm you would likely lose most of the brightness of the component, but there is surely some flexibility.
Then we create another boolean constant that we will invert each loop iteration D. To keep the value from previous loop iteration we will make use of Shift Registers E. Imagine a Shift Register as a memory block that "remembers" what was wired to it the last time it ran.
To add a Shift Register, first wire the data through to the while loop, then right-click on the terminal and select "Replace with Shift Register This way we can now keep on inverting the value each time the while loop runs, hence turning the LED on and off.
Then we should add some timing Fotherwise our code will keep switching the LED way too fast for us to see! Make sure the timing is configured to miliseconds by double-clicking on the timing function and selecting "Counter Units" to "mSec" G. Finally we can also create an indicator to double-check that our inverting logic is actually working as expected H.
You can try tweaking the timing value as shown in F of Figure 3 and see how that changes the frequency of the LED switching. Don't have an AAC account? Create one now. Forgot your password?

Part 4 will be out soon, though! Sign In Stay logged in Or sign in with. Continue to site.But besides that, I would not know what exactly that would entail. Are these hardware platforms intended for two totally different kinds of operation? I don't know if this kind of operation is considered to be a fairly complex affair for the Arduino UNO or whether the myRIO is better suited for this kind of task in terms of hardware capability.
I think there are lots of people that have used Arduinos for drone type applications - but I think the myRIO is pretty well suited to this sort of thing and you should be able to take advantage of the built-in onboard functionality! From what you have said, it does seem like the myRIO is better suited for my task due to it's hardware integration.

Message 3 of 4. Message 4 of 4.Hello everyone! I hope you all will be absolutely fine and having fun. First of all, I will give you a brief introduction on servo motors and then we will proceed towards their interfacing with myRIO.
Servo motor is an electronic device with a small output shaft. This shaft can be adjusted at different angles for the different purposes. We can adjust this shaft by sending a signal usually known as servo coded signal. Servo motor is able maintain a particular angle as long as it has the servo coded signal at its input. Servo motor changes the angular position of its shaft with every change in the servo coded signal applied at its input. I have already designed and shared Servo Motor Control in Proteus.
If you are using the servo motor for the first time then you must go through this tutorial. This design is always helpful to the beginners. DC motor is a simple device having two input terminals. We just have to supply voltage at its terminals and it starts rotating in either direction depending upon the polarity of the applied voltage.
Whereas, servo motor has three input terminals, two terminals are for the power supply and one is for sending servo coded signal to rotate at specific angle and in specific direction as well. It is easily available in the market and has a low cost. There are a lot of real life applications associated with servo motors. For example, robotics, elevators, air crafts, remote controlled appliances, vehicles, solar tracking system, automated baby cradle system, conveyor belts system and a lot more.
The further detail about servo motor control using myRIO will be given later in this tutorial. It has three input terminals. Two terminals are for the power supply and the third is for sending the servo coded signal. The electrical or electronics projects where there is a need of motion, servo will be the best option in this case.
The shaft of the servo motor changes its position corresponding to the servo coded signal applied at its input. It has a wide range of applications including robotics, automated baby cradle, solar tracking systems, elevators etc.
Servo motor is shown in the figure given below. I have tried my level best to provide all the necessary detail about servo motor control using myRIO. I hope you have enjoyed the tutorial and will appreciate my efforts. If you found something missing, please let me know so that I can update this tutorial accordingly in order to avoid any future inconvenience.
