With S51 SCM procedures L298 driver chip (C language) there are six ports, input ports, respectively, for P1.0, P1.1, P1.2, P1.3, P1.4, P1.5. Six output ports were P0.0, P0.1, P0.2, P0.3, P2.4, P2.5. which P0.0, P0.2, P2.5 output high-low. P0.1, P0. 3, P2.4 output PWM pulse signal. procedural requirements P1.0-P1.5 as long as any one to 1 , the P0.0, P0.2 output high when the P1.2 or P1.3 to 1 , P0.1, P0.3 same PWM duty cycle output signal
