The DRV8889-Q1 evaluation module (EVM) allows easy evaluation of the DRV8889-Q1 device. The DRV8889-Q1 device is an integrated, dual H-bridge driver for automotive stepper motor applications.
The evaluation module allows the device to be configured for all of its functional modes including microstepping down to 1/256 step resolution, multiple decay modes for smart tuning, stall detection, and slip detection. An MSP430F2617 on the board provides the STEP, DIR (direction), and SPI signals to control the DRV8889-Q1. These settings are configured in the downloadable device GUI available for this EVM.
For more information on this evaluation module please refer to the DRV8889-Q1EVM hardware and GUI user guides.
