Richard,
STSPIN220 has 0.4ohm HS+LS Rds(ON). DRV8428 has 1.5ohm HS+LS Rds(ON). What is the output current for each winding. If the RMS current is higher than 0.7A, we can check DRV8426 or DRV8424 to support a higher current application.
On the EVM, DRV84xxEVM uses MSp430 as the controller. The firmware is available on ti.com
