Hi,

I have a very quick job involving controlling a brushed DC motor 12V/3A and it has a quadrature encoder. Is there any motor controller board suitable for that purpose?

    Hi Jan

    You may need a MCU+Motor Driver solution.

    For Motor Driver, you can find devices and its EVM such as DRV8840, DRV8842, DRV8412. For the MCU controller, you can find TI C2000 serials controller with dedicated eQEP module. Here is a QEP user guide for you reference.

    And DRV8412-C2-KIT may be a quick startup kit providing most things you need.

    Thanks,

    Hi Wilson,

    Thanks

    I have a Tiva C Series Launchpad, which I can possibly use as QEP. Is there any example code for QEP module on Tiva?

    Is there a simpler (cheaper) motor driver board to complete the solution?

    Hi Jan

    Yes. You can use Tiva launchpad or C2000 launchpad to build lost cost solution. The rest is to find an EVM of DRV8x parts, or change and build you own motor driver boards with the gerbers and source files we provided along with the EVM.

    For QEP source, maybe you can get more support from Tiva forum. But I think you will find more resource to the C2000 launchpad which is more dedicated to motor control.

    Jan, you can also consider the DRV8828, which is a lower cost option with a higher Rds(on).
