Hello, I would like to know if it is possible to control a TB6612 via MCP23008 and if so, how? I want control of stepper motors via I2C but for architectural reasons, I can utliliser shield for raspy 2. Thank you in advance.
Sincerely FX

Hello, je souhaite savoir s'il est possible de piloter un TB6612 via un MCP23008 et si oui, comment ? Je souhaite piloter des moteurs pas à pas via I2C, mais pour des raisons d'architecture, je ne peux utliliser le bouclier pour raspy 2. Merci d'avance.

Yes it is possible - but the MCP23008 does not have PWM capability, so you would not be able to implement microstepping.
Another alternative is to use the PCA9685. That has PWM and is the chip we use to drive the TB6612 chips on the Motor HAT.
