@misan the same thing above ^^^^^^ aplies to the a4950. how do you configure all 3 pins? (in1, in2, vref)?

@sanchosk the datasheet says that pwm1 and pwm2 have "200kΩ pull-down at internal ". does that mean i should pull them low?

I am designing an arduino mega shield so that is compatible with marlin firmware for a reprap. it will use 4 attiny85s running dcservo

should there be a resistor somewhere beween the encoder pins and the attiny85?

what is the best h bridge to use, and also, where can i find a good tutorial on how to use h bridges/how they work?

@misan "Encoders have two signals so not only steps can be measured (angle) but also the direction of it (sign)" when connecting encoder a and encoder b to the attiny(or...

@misan so it is okay, or not okay for the dc motor power wires and the encoder ab wires to be inverted?
