Can I use the incremental encoder to control the motor with the eQEP interface instead of the ENDAT2.2 interface.Is this method possible?

Hello

There was a TI design that was done to demonstrate the hardware and firmware that could be used to implement a sinc cos encoder interface using the AM437x. it is available at http://www.ti.com/tool/TIDA-00178

This is a standalone example that provides an illustration of the capabilities of the AM437x and is not intended to be used as the basis of and product design. This interface is not currently supported by the PRU-ICSS-Industrial package.

thank you very much ,and i have another question. if there is no code, how can this function to use it? the user need to write their own?

I apologize, this example only includes a description of software and a binary file. The assembly source is not included.

Thank you for you reply. How do i get these description of software and a binary file? And the TIDA-00178 seems to be unable to buy.

Regretfully board shown in this TI design is not available for purchase and the source code for this design is not available. The TI design document only contains a text description of the software and a binary executable but not the source. The The TI design contains the schematic, Bill of Materials, PCB, and Assembly drawings that were used to create of the board.

At this time, we do not have a date for when the sin/cos encoder interface will be available on a Sitara EVM or in the PRU-ICSS -Industrial software.
