Bohdan,

I suggest taking a look at the DRV8840 or DRV8842 kits with the links below. You can purchase the kits or you can also just download the MSP430 code from the tool folder. Both use a MSP430F1612, but code should port.

Thank you for your response. But I would need more simple solution - one direction. Brushes of my motor arangement is one way only (car cooling ventilator), that is why I did post it to Power Forum.. I do not understand how put together 3.3V of processor and 24V DC of motor.
