Interested to know more details specially regarding DRV89XX driver #1

Looks like very ambitious project. It covers lot of areas in all-in-one electronic design. It will be useful to share some details in readme file.

I wanted to know about your driver library for DRV89xx as there is no other library I can find on github for same chip.

If I am not wrong you are using 4 DC motors for your project. I have following questions:

How much maximum current each motor can draw?

Are each motors are unidirectional or bidirectional?

My goal is to drive 4 motors for window blind control but can I drive 4 zones of LEDs for home lighting projects?

I will appreciate if you can provide some details.

Thanks.

Hi there,

You are correct, I'm using 4 DC motors in my robotic car. These motors are bidirectional (I can find the type number when I get home)

The maximum current per motor should be around 6A

You are right that there arn't many libraries out there, which is why I wrote one for the mbed platform. There is however already one out there for Arduino: https://github.com/josephduchesne/DRV89xx which I used as an example to start.
