> I would like to use the MSP430 as a universal test driver for stepper motors to control the speed, direction, full or half step and so on. The Timers in MSP430 is more 'universal' then the L297. The L297A with a clock pulse doubler compared with L297, L297 and L298 driving a bipolar stepper motor with up to 2A phase currents (click image to enlarge), and pin function – pin connection for L297 and L297A.Ĭomplete read of The Using of L297 in Stepper Motor Driving Applications can be download in this application datasheet article in pdf filetype (source: . The Stepper Motor Chopper Driver is a Bipolar Stepper Motor Drive with easily adjustable current control up to 2A, based othe SGS-Thompson L297 and L298 stepper. MSP430 can be used to emulate the functions of L297 and directly drive other devices to handle the large inductive load of stepping motors. You will be taken into sections discuss the advantages of L297 + driver combination, the used with an L298N or L293E bridge driver, stepper motor basic types (unipolar, bipolar and variable reluctance),īipolar permanent magnet stepper motor, drive sequences for a two phase bipolar stepper motor, generating suitable phase sequences for half step, one-phase-on full step and two-phase-on full step operation.Īlso, there are circuit diagrams such as the L297 contains translator (phase sequence generator), a dual PWM chopper and output control logic, the L298N connected to the first phase of a two-phase bipolar motor, L298N module is a high voltage, high current dual full-bridge motor driver module for controlling DC motor and stepper motor. L298 Dual H-Bridge Motor Driver L298 is a high voltage and high current motor drive chip which receives TTL logic signals. You will be described with the operation of the L297 integration control circuitry and also figure out how it is used.
