The easiest way will be to order an EVM: https://www.ti.com/tool/DRV8889-Q1EVM

See the web GUI (https://dev.ti.com/gallery/view/MotorDriversBSM/DRV8889-Q1/ ) and the user guide stall detection section - https://www.ti.com/lit/ml/slvubm4a/slvubm4a.pdf#page=9 Using the EVM and GUI they will not have to do any programming or build a board.

Finally, see the app note Sensorless Stall Detection With the DRV8889-Q1

Best,

Jacob
