BOOSTXL-POSMGR: Redesign According to BOOSTXL-POSMGR BISS-C Communication

Part Number: BOOSTXL-POSMGR
Other Parts Discussed in Thread: TIDM-1010

Hello there
I am thinking of using an encoder that communicates with BISS-C. However, as far as I have researched, there is no direct support for the BISS-C interface in C2000 MCUs. It is necessary to design a converter together. I have read that your BOOSTXL-POSMGR product is used as a BISS_C converter. There are some features on it that will also perform different functions. I want to make a BISS_C converter according to the "www.rls.si/.../aksim-2-off-axis-rotary-absolute-encoder" encoder that I shared this link. In my design, I will design a card with a minimum size with reference to the BISS-C converter part of your BOOSTXL-POSMGR product, of course, if the interfaces that will run this encoder are available in this converter.
1- Can I communicate with the encoder whose link I shared using your BOOSTXL-POSMGR product?
2- How can I do it for only one BISS-C converter C2000 family with reference to your BOOSTXL-POSMGR product? (You can mark and show the structures I need to put from the BOOSTXL-POSMGR schematic)
Best Regards

    Hello Huseyin,

    We use the BOOSTXL-POSMGR for connecting to encoders supporting BiSS-C, T-format and EnDat22 encoder protocols.  Note the booster pack handles electrical signals - it doesn't interpret the protocol packets.  This is handled by the F28379D connected via a LaunchPad.

    Figure 1 of the C2000 BiSS-C (https://www.ti.com/tool/TIDM-1010) documentation (https://www.ti.com/lit/tidue73) shows the BOOSTXL-POSMGR blocks that are used by the encoder interface.  In this diagram the BOOSTXL-POSMGR is labeled as TIDM-1010.
