I2c multiple stepper controller/driver for Arduino or Rasbery?

[Bogdan Bednarczyk]

Hi guys,

I have trouble getting to the space as I still work in the afternoons finishing at 11.30pm.

But I miss the buzz around the space.

Does anyone know or heard of a I2c driver for multiple steppers (16+ and chaining multiple of 16) like NEMA17 similar to Adafruit 16-Channel 12-bit PWM/Servo Driver - I2C interface - PCA9685
https://www.adafruit.com/product/815. But they use 3 pin servos instead of steppers.

All motors can use the same driver currents and they will be loaded similar loads. Allthough I can see the possibilities of using different loads and currents for other projects, at this time no need.

Thanks in advance

Did you find anything Bogdan? 

Some time ago we made some little DRV8825 stepper drivers that also had a small micro on same board.   You could use those, but would have to write the code for the pic/atmel

Hi Lachlan

No, not really
I found one video based on PI but i did not think it will do the numbers as it did not have I2c

writing code is not a problem if i have some samples.

did the board have I2c address?

is there more info on line somewhere ?

My problem is that I don't understand enough of electronics. I wish I did study earlier in life. I know there is always a time to do more.

In my last semester of my master degree, I did a project where I used an arduino controlled by a pi3 for l2c components. I think you can do it in a similar method, you just have to write some serial communication code on pi3.
