Using in Unity3d

[gagagu]

Hi,
i want to use you library in Unity3d and i will get an error which i don't know to handle. I've switched your Project and Unity3D to .net 4.6 and both are working correctly (separate).
The ArduinoUploader.dll and RJCP.SerialPortStream.dll are compiled also with 4.6

When i will start the Project in Visual Studio the Music sounds out of the Arduino correctly

I've copied the following files to unity:
ArduinoDriver.dll
ArduinoDriver.dll.config
ArduinoUploader.dll
IntelHexFormatReader.dll
NLog.dll
RJCP.SerialPortStream.dll
RJCP.SerialPortStream.xml

When i will start my Project and send the Music to the Arduino the yellow LED is blinking and i will get the following error:

IOException: Device Error
RJCP.IO.Ports.SerialPortStream.WriteCheckDeviceError () (at :0)
RJCP.IO.Ports.SerialPortStream.WriteCheck (System.Byte[] buffer, System.Int32 offset, System.Int32 count) (at :0)
RJCP.IO.Ports.SerialPortStream.Write (System.Byte[] buffer, System.Int32 offset, System.Int32 count) (at :0)

ArduinoUploader.ArduinoSketchUploader.UploadSketch (System.Collections.Generic.IEnumerable`1[T] hexFileContents) (at :0)

I know ist not directly your issue but i'm hoping that you can identify the Problem when you see the error message. May be some files missing?

THX Forward!!!

Hey Gagagu,

Interestingly I was also looking into getting this library working on Unity3d also.
I have downloaded the source, and changed the Unity API compatibility level to 4.6.

Then when using all the source files you can see the issue is with the SerialPortStream library where the DeviceError is thrown. There is a lot going on behind the scenes where it actually uses a native windows (or unix) library. I think this is the issue where from Unity the SerialPortStream isn't communicating to the port library natively.

However, I did manage to get half of this running in Unity (the communication, not uploading the software hex).
If you're happing uploading the ArduinoListener to your Arduino using the standard Arduino software (not using the autobootstrap the package this package does), and simply using this library to communicate with the Arduino Listener.

To do so, download the source files from this repo and drop the in unity.
Download and extract just the 'hardware' source files from ArduinoSketchUploader

Swap the namespace from 'using RJCP.IO.Ports;' to 'using System.IO.Ports;'
Swap the class from 'SerialPortStream' to 'SerialPort'
Remove the last method in 'InitializeWithAutoBootstrap' in 'ArduinoDriver.cs'

Include the other library used for Arduino Driver (NLog.dll)

That should be enough to get the sample mario tunes program running.
However, the port library originally supplied is supposedly better, check the readme.md in SerialPortStream
