Honored ContributorSimple hardware for Endat 2.2 implementation
Hello, I recently received an optical encoder from Heidenhain. It works with the Endat 2.2 protocol. I would like to use this encoder with a dSpace station, using parallel I/O connection. ...

Honored ContributorHi Samuel,
Any FPGA is fine. I recall building an Endat interface with a FLEX10K device (which is really old). You should use a Cyclone IV device. Do you have the user manual for the encode you are using. If I recall correctly, they have a serial interface with RS485 logic levels. Its pretty easy to create a state machine to read the serial encoder position and write it as a parallel word. I'm not sure what a dSpace station is. If you send me links I can take a look at the data sheets. I can try to dig up the VHDL code I wrote too. You don't have enough posts to post links yet, so just send them to my forum name (its my email address). Cheers, Dave
