I have a Tic36v4 driving a 3.4A Stepper working well with a Nordic nrf52840 I2C interface. I have a smaller stepper motor, possibly two, that I need to add and drive on the same I2C bus. Because it is a smaller motor, I was going to use some TicT500’s to drive those. Am I going to run into issues mixing Tic types on the same I2C bus? I have all of the motors working with their individual controllers from the Tic Control Center, but now need to add them together on the nrf52840 bus. Would it be advisable to stay with just one Tic controller type? I’m concerned a little about arbitration, but the motors will have seconds between their operation and never simultaneous operation.
Hello.
It is fine to control multiple Tic models on the same I²C bus. You can configure them with unique device numbers (which specifies the 7-bit I²C address to use) so you can specify which one you are addressing with each command. You can find more information about controlling multiple Tics with I²C in the “Setting up I²C control” section of the Tic user’s guide.
