AM4377: BiSS encoder question

Yong-kyoung Kim
Intellectual 470 points
Part Number: AM4377
Other Parts Discussed in Thread: TIDEP0022, SYSBIOS

Hi, I've tried to implement BiSS-C master in AM4377 board(customed from IDK_AM437X)

I want to receive 32-bit data from BiSS encoder, but the code for PRU(biss_master_bin.h) is limited under 22-bit...

How could I change it for 32-bit data?

I've tried some changes in pru0_BiSS.p(in the tldc920)..

Thank you,

Kim.

    Hi

    The TIDEP0022 illustrates how the ICSS-PRU can be programmed to support the BiSS C Master protocol. The TI design document provides a summary of the hardware (an AM437x Industrial Development Kit (IDK)) and demonstration software that was based on the older SYSBIOS Industrial SDK .

    This TI design is provided as a simple stand alone illustration of PRU-ICSS programming and is not intended as reference for BiSS C implementation, the basis for product development, or use with the PRU-ICSS-Industrial SDK examples.

    This TI Design is a first step toward the development and inclusion of BiSS C support in the PRU-ICSS Industrial SDK.
    We encourage customers who are interested in rapidly developing applications using robust BiSS C implementation on the AM437x to wait for BiSS C support to be included in the PRI-ICSS-Industrial-Drives package.

    At this time, there is not a published schedule for this development. Please contact your TI representative to discuss this further.
