Hi,
I connect my Unity project with microprocessor which will be my “gamepad” for simple 2D game. I need to use serial port for connection with device so I added dll to Unity, which should make it works.
Sounds simply, but when I tried to use my library, Unity shows error:
Error log
Unhandled Exception: System.TypeLoadException: Could not load type ‘STMInputDLL.STMInput’ from assembly ‘STMInputDLL, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null’.
