Infineon DC Motor Shield with TLE94112EL

Introduction

This DC motor shield can be assembled on Arduino Uno compatible development kit.

Lab setup

 

Platform IO Coding

wire.h is not recognized at first, so, inside “platformio.ini,” lib_deps = Wire needs to be included to avoid an error when main.cpp was complied.

• lib_deps = Wire, TLE94122

Arduino Coding Explanation

• Header Files

  • #include <TLE94112.h>
  • #include <Tle94123Motor.h>
  • #include <tle94112_conf.h>

• TLE Object

  • Tle94112 controller = Tle94112();

• Tle94112 Motor Objects

  • Tle94112 Motor motor1(controller);
  • Tle94112Motor motor2(controller);

• void setup()

    // Enable MotorController Tle94112
    // Note: Required to be done before starting to configure the motor
    controller.begin();
    // Connect motor1 to HB1 and HB2
    motor1.connect(motor1.HIGHSIDE, controller.TLE_HB1);
    motor1.connect(motor1.LOWSIDE, controller.TLE_HB2);
    // Drive HB1 with signal from PWM1
    // Note: This allows to control the speed of the motor
    motor1.setPwm(motor1.HIGHSIDE, controller.TLE_PWM1);
    // Set PWM Frequency, default is 80 Hz
    motor1.setPwmFreq(motor1.HIGHSIDE, controller.TLE_FREQ100HZ);
    //when configuration is done, call begin to start operating the motors

    motor1.begin();
