Place another terminal, label it +12V (or your target motor voltage), and connect it to VMOT . Tie the corresponding power ground to the motor system ground.

How many microseconds should your STEP pulse be? Does your DIR pin change too close to the rising edge of STEP? With the simulation, you can connect a virtual oscilloscope to the STEP and DIR lines. You can watch the motor’s virtual coils (1A, 1B, 2A, 2B) respond to your microcontroller code in real-time . If your timing is off, you fix it in the code—not with a re-spin of the board. a4988 proteus library

Open the installation directory of your Proteus software (e.g., C:\ProgramData\Labcenter Electronics\Proteus 8 Professional\Data\LIBRARY ). Note: ProgramData might be a hidden folder. Does your DIR pin change too close to

High step rates (very low delayMicroseconds values) can overwhelm the Proteus simulation engine CPU limits. Increase the step delay to see smoother visual rotation.
