I just finished making the L298/L297 Circuit for a Bipolar 2-Phase stepper motor... But before hooking it up with my microcontroller circuit i want to check n make sure the circuit is working fine... How do i check it and what should be the voltages on the output of the L298 and what should be the voltages on the Clock,Enable,CW/CCW and Reset pins of the L297...
I connected the chips to 5V and the Vdd of L298 to 30V and I am getting around 6V on the above mentioned pins of the L297 (It would be safe to connect it to a uC?) and on two outputs of L298 I am getting 0V and 17V on the other two...
Why 17V? Should it be this way...?
Secondly i wanted to know which wires of the stepper motor would go into the four outputs? Does the order matter... as when i change the configuration the voltages on the output change....
Regards
