Connect encoders directly or via USB-Board?

[tincan]

Hello,

 

I have read about rotary encoders in this forum. I am hitting the language barrier here, so please help me understand.

 

I know there are USB-boards that allow the connection of encoders. They determine rotation direction. Is it absolutely necessary? Can we wire them directly (common ground and one "button" input for each left and right) to a USB interface without encoder support? So that FSUIPC determines the rotation direction?

You can do, but FSUIPC won't determine it automatically. There'd would just be the two button inputs with different phasing determining direction.  You'd need to do the programming. You'd probably also need to increase FSUIPC's scan rate as the pulses could arrive too fast else and give you wrong results.

 

There's a discussion about this on page 24 of the FSUIPC4 Advanced User's Guide.
