Linuxcnc Parallel Port Driver. The L297 Stepper Motor Controller IC generates four phase drive signals for two phase bipolar and four phase unipolar step motors in microcontroller controlled. Buy L297 L297/1 Stepper Motor Controller Driver IC with fast, low-cost shipping from oddWires.

The L297 Stepper Motor Controller IC generates four phase drive signals for two phase bipolar and four phase unipolar step motors in microcomputer-controlled applications. The motor can be driven in half step, normal and wawe drive modes and on-chip PWM chopper circuits permit switch-mode control of the current in the windings. A feature of this device is that it requires only clock, direction and mode input signals. Since the phase are generated internally the burden on the microprocessor, and the programmer, is greatly reduced. Mounted in DIP20 and SO20 packages, the L297 can be used with monolithic bridge drives such as the L298N or L293E, or with discrete transistors and darlingtons. Key Features • RESET INPUT & HOME OUTPUT • FEW EXTERNAL COMPONENTS • NORMAL/WAVE DRIVE • CLOCKWISE/ANTICLOCKWISE DIRECTION • HALF/FULL STEP MODES • PROGRAMMABLE LOAD CURRENT • ENABLE INPUT • SWITCHMODE LOAD CURRENT REGULATION Circuit Diagram. Extend the Runtime of Your Battery-Powered Applications The stepper motor driver, brushless DC motor driver, dual brushed DC motor driver and single brushed DC motor driver are optimized to deliver low noise, minimal power consumption and standby mode of operation along with features such as extreme position accuracy and motion smoothness with up to 256 micro-steps per step.

This circuit allows you to control each step, in full-step mode. Meaning: You can tell it to move one step in either direction (of course you can make it move fast and it will continuously rotate). The two inputs are a direction and a pulse.

In the next section you will find a program to control this using xPC.
