  This demo is based on the GDSCN832R-EVAL board, it provides a description of PDI 
communication using SPI.

  This demo cannot be directly compiled and downloaded for use.

  Before testing this demo, users are required to be members of the ETG organization 
in order to obtain access to the SSC TOOL for generating protocol stack code.
  Users must first complete the download of the SSC TOOL. Refer to the ETG official website 
for download instructions: 
   https://www.ethercat.org/en/downloads/downloads_01DCC32A10294F2EA866F7E46FB0285F.htm.
   after the download of the SSC TOOL,The DOC directory of the reference project
the steps in the AN246 document to generate the protocol stack code and port 
the stack code into the current project for testing.

After system start up, use the main station TwinCAT to 
communicate with board. when the LED1 lights up, this demo runs successfully.

   On the GDSCN832R-EVAL board, JP6, JP7, and JP8 connected to the H side, 
JP4 and JP5 on the EVAL board connected to the 1 side,JP9 and JP10 connected to 
SCS and GPIO3.
