How to use a singlechip to send a pulse to a two phase stepper motor driver, and how to connect with the stepper motor? Is there a program?
Connection of work voltage:The VCC is connected with a DC power supply (Note: 10V < VCC < 32V).GND: DC power supply is connected to the negative.See product descriptions in detailSignal input terminal optocoupler isolation connection methodThere are two ways to connect the input signal interface: the user can use common anode method or common cathode connection method according to the need.1, common anode connection: CP+, U/D+, EN+ connected to the power supply control system, if the power supply is +5V can directly access, if the power is greater than +5V, it shall be an external plus a current limiting resistor R, providing 8 15mA driving current to drive the internal coupling. The pulse input signal is connected through the CP-. At this point, the U/D- and EN- are active at low levels.2 common cathode connection method: 9 respectively CP-, U/D-, EN- connected to the control system of the ground (SGND, and power isolation); +5V pulse input signal through the CP+ to join; at this time, U/D+, EN+ in high level effective. The connection value of current limiting resistor R is the same as common anode connection method.Note: EN end is not connected, when EN is valid, the motor rotor is in free state (offline state), then you can manually rotate the motor shaft to do the adjustment for you. Once the manual adjustment is complete, then EN is disabled to continue the automatic control.
The EN+ motor control: offline positive end.Will EN-: Motor off-line control negative terminal.Motor winding connection:1 A+: A+ phase winding connection.A-: A- is connected with the motor winding.B+: B+ is connected with the motor winding.B-: B- is connected with the motor winding.
Signal input1 CP+: positive input pulse signal.The CP- pulse signal: negative input terminal.U/D+: the motor is reverse control terminal.U/D-: the motor is reverse control negative end.
To enable EN, give direction DIR, and then step a pulse, EN is usually +, DIR random, which direction of their own try, with wire points can try out, more hands
