I am getting an error message ("Invalid or no response after the first st3) when I change my source from simulator to EEGNeuroAmp. I checked my device manager and the NeuroAmp is connected to Serial Port COM port 3, so tried to change COM port from auto detect to COM3 in the source properties, but no luck. Also, I thought it was odd that the NeuroAmp element has 11 channels and 40 qeeg channel outputs, while it only has 2 channels on the physical device. I am currently just trying to display the raw signal (oscilloscope) to make sure I can receive input from my NeuroAmp before I proceed to develop my design. I should also mention that I am still actively using this NeuroAmp in clinical practice on a daily basis, therefore, I am very cautious not to change any configurations that I don't fully understand. It currently works perfectly fine with Cygnet.

disclaimer: I just got my dongle yesterday afternoon, so I am very new to working with BioEra. I exclusively worked with C# programming in the past, so I am still trying to understand the drag-and-drop style of programming in BioEra. I have been trying to learn by analyzing (and attempting to reconstruct) the examples provided. If anyone has suggestions on resources (i.e. textbooks, videos, tutorials, etc.) that could accelerate my learning, I would be incredibly grateful!

I provided a link below to a screenshot I took with the error message and my set up.

There are many versions of Neuroamp. The most recent version has ability to do QEEG, that is why there are so many output channels. You can simply ignore those extra outputs.

Neuroamp needs to be properly configured. I will try to connect my Neuroamp tonight and see if it works for me. Then post the results here.

The flow programming (as in BioEra design) has many advantages. I find it is much easier to understand and modify later because you can see everything at once (rather than analyzing each line of the code like in C#).

But it is also possible program in java using ExpressionEvaluator (java is very similar to C#). See the note about advanced form of the expression (which is just java code).

I start many of my (private) projects as BioEra design, and then create custom java for special purposes.

There are no tutorials or videos. Most people learn by analyzing the examples and snippets. Feel free to ask questions here.

Thank you Jarek! I appreciate your helpfulness and speedy response times! That would be great if you could post your results with your NeuroAmp! I am open to learning any and all programming languages that will help me in my project! C# was just the main language I needed to learn to get started with Unity5. I can definitely see the advantages of flow programming though!

Here is an example snippet which demonstrates how to configure and use EEGNeuroamp:

I tried one of my older designs, and it also didn't work. So the configuration is important. I should change the default values.

Wonderful! I will give it a go! Thank you.

I contacted the Neuroamp support, and updated the configuration further in the above snippet.

If you already downloaded, you may want to do it again.

It has been working perfectly. Thank you!
