Suppor for I2C Based motor controller

[res2cpu]

Describe the problem you have/What new integration you would like I would like some kind of support for some kind of I2C based motor driver like the WEMOS D1 MINI MOTOR DRIVE SHIELD.

Please describe your use case for this integration and alternatives you've tried: I have used this motor driver for roller blind controllers and as they use the I2C bus it saves pins, is small and cheap. In my use case i control 4 motors, with a traditional motor driver i would need a minimum of 8 pins, this way i only require 2.

Additional context A arduino library for this already exists here, but I've had no luck getting it to work with esphome (lack of knowledge on my part i believe)

I've been working on tackling this myself. I have the driver set up as a custom component for now as well as ESP Rotary library for encoder feedback, using custom home assistant services to start, stop, and reverse the motor. But so far I cannot get the motor driver to respond. Will post update when I have a solution working, hopefully in the next couple of days.

@kwdaily Any news on this matter?

sigh Are you telling me this issue/request is two years old? I just posted a request myself basically requesting the same thing. Damn

No, I ended up writing my own driver using the I2C commands from the controller datasheet

Dont suppose you mind sharing it, do you?

YAML is the config (minus my credential info), sliding_glass_door_lock.h.txt just needs the .txt removed to turn it back into a .h file, which is included with the YAML. Fair warning, I scrapped this approach for my application but it was working at the time. If you have any questions, I will do my best to answer them! Hope this helps!

I managed to get them working by directly communicating with the 16-channel PCA9685 that sends PWM to the 2 x TB6612 on the board. Sending 0% or 100% PWM turns the channels off/on for the in1 and in2 for forwards and reverse and then variable PWM for the speed control pin on the TB6612s. No need to add libraries as the PCA9685 works with ESPhome already.

Forgot to mention that I'm using the Adafruit i2c Quad DC or two-channel Stepper Motor Driver Featherboard.
