In most applications, the control of stepper motors is implemented using a microcontroller. However, there are many applications that require manual control of the stepper motor using the controls on the instrument panel. In an in-vehicle detection instrument designed by the author, the main body of the instrument needs to be placed in the car, while the target light source controlled by the stepping motor is outside the vehicle, and the target light source can be manually positioned at any point according to a certain curve. In order to simplify the operation and simplify the design, the author designed a control circuit for the stepping motor by using a switch.
2 stepper motor switch control circuit shown is the author designed switch control stepper electric activity theme paper with a switch manual control stepper motor implementation method Hunan Xiangtan City Radio Co., Ltd. Zhou Xiaohui control circuit, and a digital potential control with a switch The up and down counters set the two expansion circuits for the counter output.
Structure. This means that the microcontroller can easily adapt to different power drive devices from different vendors. If the microcontroller's core is all stopped, use the emergency stop pin of the ST72141K microcontroller, which allows the output of all peripheral components to go directly into tri-state mode. The ST72141K has an 8-bit timing circuit that can be automatically calibrated over the entire operating speed range of the motor. It produces six status signals with an accuracy of better than 1.2% and does not have to be set in software. A second timing circuit (6-bit) can generate a pulse width modulated signal for voltage control or an internal voltage reference signal for power control. The power mode comparator that is usually required in this case is also integrated in the ST72141K. In addition, you can use its SPI interface to exchange information with other controllers for other purposes such as detection or maintenance. At the same time, an 8-bit A/D converter and another independent 16-bit timing circuit can further process other control functions, such as using sensors to monitor temperature or regulate pressure.
In addition to these basic functions, the ST72141K microcontroller also includes an oscillator safety protection circuit (OSG), a reset circuit when the power is turned on, an undervoltage detection circuit, and a low-voltage switch. Like all other products in the ST series, the ST72141K can also use a quartz oscillator or a resonator to generate an external 16MHz signal (the internal clock signal is 8MHz) - the clock signal fails and is integrated into the device. The Oscillator Safety Protection Circuit (OSG) provides its own time base signal to maintain the monitoring circuit to continue operation and to transfer the microcontroller to a predetermined state. In addition, a full set of control and adjustment tasks can be performed with 8kB of RDM and 256 bytes of RAM. The ST72 series of microcontrollers can be programmed in C or in assembly language.
