Package: piServoCtl
piServoCtlOverviewThis is a servo motor control library for Raspberry Pi. In addition to normal servo motors, continuous rotation servo motors can also be controlled.
It utilizes hardware PWM. Therefore, the servo motor can be moved smoothly. Since you are using pigpio, you need to install pigpio and start pigpiod. To start pigpiod, you need to press thesudo pigpiodcommand or run pigpiod automatically.In addition, you can easily make an RC car by using two rotation servo motors. Use the Drive class to set the GPIO pin and servo motor. You can easily implement the steering function by using the steering method.Installationsudo pip3 install piServoCtlUsageFirst, start pigpiod (if it is not started). Then import the module. The module name is "piservo". Please note that it is different from the name when it was installed.sudo pigpiodServoThe easiest way is to useServo(gpio)(wheregpiois the GPIO pin number). Use GPIO that supports hardware PWM.You can control the servo motor with thewritemethod.DriveThe easiest way is to useDrive(left_gpio, right_gpio)(left_gpio,right_gpioenter the GPIO pin number). Use GPIO that supports hardware PWM. You can swap theleft_gpioandright_gpioto flip the front and back of the car.You can control the car with thesteeringmethod.DemoServofrom piservo import Servo
