Motor Driver Block using Soft PWM of WiringPi Library.
This block controls both the magnitude and direction of a DC motor with an H-bridge such as the DRV8833 or the SN754410 using Soft PWM of the WiringPi library.
The reference zero speed is set with high voltage at both motor terminals (both PWM signals at full duty cycle). For the DRV8833 driver this creates a highly linear response and eliminates the typical dead band around zero speed. This increases motor response but may have a larger power draw (this has not been measured).
