FPGA Crio encoder SSI protocol

[FrankyCam]

Hello everyone

  Does anybody work with SSI protocol encoder and Crio FPGA? I wrote a simple program that try to implement this protocol on Crio FPGA, but i obtain chaotic data. I use a rs422-TTL converter to transform encoder signal (Rs422) to TTL signal for Digital high speed NI9401. Anyone could help me? any suggestion?

Thank you

Hi Francesco,

take a look to this link.

Thank you for your answer, Andrè.

I've not problem with signal conversion from rs422 to TTL, because i made it with electronic component who switch voltage level. My problem regards SSI protocol.

Hello everyone,

  I've solved my problem. I'm able to read angular position from an Eltra Encoder with SSI protocol using labview FPGA.

Thanks everyone for the help

Can you post your solution. I was looking for something similar?

I've just modified an example on Labview site. Let me your mail in private message or in this forum so I'll send you my program.

Can you provide a link to the example you modified? I am trying to work with SSI and a cRIO as well.

Thanks,
