Original question:

AM5708: Timer usage

AM5708: eCAP functionality

user5355349

Part Number: AM5708

We want to know if using the ECAP function of 5708 can capture the A-phase and B-phase pulse of the encoder, using the software SDK4.3, Linux operating system.

Is there a driver for use added, how should the software operate it?

    Hello,

    The eQEP peripheral is best suited to capture the A-phase and B-phase pulses of an encoder. As of Processor SDK 6.0, TI does not offer an out-of-the-box software solution for capturing encoder output (on eQEP, ECAP, or timer).

    If you want to develop your own eQEP encoder software, please reference Ron's answers on your post Encoder Capture for getting started information.

    Regards,

    One additional note: Another option for developing eQEP software is to use a real-time processor to control the eQEP (e.g., the PRU), and then transfer necessary information between the PRU and the ARM. However, this option would also require PRU firmware development.
