Hi,
I'm using a myRIO for a school project and we have to measure an quadrature encoder. There is only one problem, when we calculate how much state changes it would undergo in 1 second it's 8.400.000, so my question is, will the myRIO build-in counter be able to count that fast?
Thanks for the reply, Laseros

Hi Laseros,
If you take a look at page 23 of the MyRIO manual (http://www.ni.com/pdf/manuals/376047a.pdf ) you will find that the max frequency for Quadrature encoder input is 100kHz. If you create a "MyRIO custom FPGA project," you can actually have a look at the FPGA code that was implemented to read the encoder signal.
Best,
Jos

Hi.
I know this thread is about 3 yrs old but the link to the manual was old so I will update it.
The newer MyRIO Manual can be found here. (http://www.ni.com/pdf/manuals/376047c.pdf)
In page 23 as Jos mentioned, there is the maximum frequency.
Best,
Yong
