Count skipping when using 2 programs to read from PCI-QUAD04 encoder

[mick1221]

I have 2 pieces of software that read from the PCI-QUAD04

Software A is legacy and is being phased out

Software B is has it's own features but will eventually include software A's features

Currently we'd like to be able to run both at the same time.

 

When I run software A or B on their own everything is fine

When I run them both at the same time Software B will see the encoder count Jump around instead of steadily climb.

do the Drivers provided by MCC only support one piece of software at a time like a serial port?

 

note: I know the Quad04 isn't made anymore this is a bug we are trying to fix before adding support for the USB-Quad08 which is our replacement

MCC's Universal Library does not support two programs controlling a single device. You can have two programs running on the same computer, but they must use separate devices. You can also control two or more devices from a single program.

This includes just reading values from it, I take it?
