How to Optimize Control Pins for Basic Movement Functions in a Robot Using L298N Dual H-Bridge?

Hello.I have a simple robot with two DC motors. Using the L298N Dual H-Bridge, what’s the minimum number of control pins I can use to give me forward, back and turn?
If I tied Ven high and relied on the “C=D Fast Motor Stop” when idle would this be bad?

Hello. In my opinion, you need all 6 inputs. You could go with 5, when connecting both EN inputs. You need the fast motor stop option. This means that both C and D cannot be controlled only inversely, but you need the possibility to drive them at the same logical level.
