encoder4_motor.get_vin_adc_raw8_value()

• Retrieves the 8-bit ADC (Analog-to-Digital Conversion) raw value of the input voltage.

encoder4_motor.get_vin_current_float_value()

• Retrieves the input voltage current value in amperes.

encoder4_motor.get_vin_current_int_value()

• Retrieves the input voltage current value in milliamps.

encoder4_motor.get_vin_voltage()

• Retrieves the voltage value of the input voltage, returning an integer.

encoder4_motor.init_i2c_address(0x24)

• Initializes the I2C address of the device, ranging from 0x01 to 0x7F.

encoder4_motor.set_encoder_mode(0x00)

• Sets the direction of the encoder mode, with options for "AB" or "BA" mode.

encoder4_motor.set_i2c_address(0x24)

• Sets the I2C address of the device.

encoder4_motor.set_motor_mode(0x00, 0x00)

• Sets the running mode of motor 1. The drop-down menu provides three options:
  • NORMAL: Normal mode, where the motor operates according to default settings.
  • POSITION: Position control mode, controlling the motor movement by specifying a position.
  • SPEED: Speed control mode, controlling the motor rotation by specifying a speed.

encoder4_motor.set_all_motors_mode(0x00)

• Sets the mode for all motors:
  • NORMAL: Normal mode, where motors operate according to default settings.
  • POSITION: Position control mode, controlling motor movement by specifying positions.
  • SPEED: Speed control mode, controlling motor rotation by specifying speeds.

encoder4_motor.set_motor_encoder_value(0x00, 1000)

• Sets the encoder value for the motor, which typically represents the current position or cumulative rotation of the motor.

encoder4_motor.set_position_encoder_value(0x00, 1000)

• Sets the position encoder value for the motor. This value is used to specify the target position or current position in position control mode.

encoder4_motor.set_position_max_speed_value(0x00, 100)

• Sets the maximum speed value in position control mode, ranging from -127 to 127.
