Hello,
I am working on a project where I am replacing a microcontroller (and code) with a new one. It listens to its master via SPI and moves 4 stepper motors according to what the master says.
They somehow are controlling 2 stepper motors off one L293D driver for a total of 2 L293D's. The two outside wires are all tied to together on all motors. The enable lines for the chips are fixed high.
How are they able to do this?
24 volts.
