Linux/PROCESSOR-SDK-AM437X: BiSS-C Interface Functionality on PRU through Linux SDK

Puneeth Bandikatla

Tool/software: Linux

Currently we are using PRU to control BLDC Motor with Incremental encoder, it works fine. Now we want to change it to BLDC Motor with Absolute Encoder.

So we need BiSS-C Interface to read Absolute Encoder, http://www.ti.com/lit/ug/tidu794a/tidu794a.pdf this guide tells how to use BiSS-C Interface Master through Code Composer Studio (CCS). But our whole development is happening on Linux SDK (ti-processor-sdk-linux-am437x-evm-04.00.00.04), So we want to use BiSS-C Master through Linux SDK.

Some old thread says, it will be included along with EnDAT Master Interface in Linux SDK, So I checked the latest Linux SDK (ti-processor-sdk-linux-am437x-evm-05.03.00.07) but I couldn't find any related information.

Is there a way to use BiSS-C Interface Master using Linux SDK, If So, please can you provide reference links to it.

Thanks

Hi Puneeth,

Unfortunately we do not have an example of BiSS-C in our Linux SDK. In the thread you referenced, Paula mentioned that the software would be included in a future version of the 'Industrial SDK' which has since been replaced by our RTOS SDK (software-dl.ti.com/.../index_FDS.html) along with ICSS industrial add-on packages (www.ti.com/.../PRU-ICSS-INDUSTRIAL-SW).

However, the BiSS-C implementation did not make it into either of those packages either. What we currently have is the zip file download on the BiSS-C Master TI Design page: www.ti.com/.../TIDEP0022. This zip folder contains code that is built using the PASM assembler that is no longer supported by TI and is replaced by the PRU Code Gen Tools.

We have a 3rd party that has successfully ported the PASM assembly code and rebuilt it with TI's PRU Code Gen Tools that may be able to help you get BiSS-C running in your environment if you would like for me to connect you with them.

Hello Jason,

It will be great if you could connect us with that team, so that we can start testing our new BLDC motor with Absolute Encoder.

Thanks
