Embedded C++ Motor Control Class — Embedded-c-cpp Code
Encapsulates motor control logic using PWM and direction pins on an ARM MCU.
class Motor {
public:
Motor(GPIO_TypeDef* dirPort, uint16_t dirPin, TIM_TypeDef* pwmTimer) : dirPort(dirPort), dirPin(dirPin), pwmTimer(pwmTimer) {}
void forward() { dirPort->ODR |= (1<<dirPin); }
void reverse() { dirPort->ODR &= ~(1<<dirPin); }
void setSpeed(uint8_t duty) { pwmTimer->CCR1 = duty; }
private:
GPIO_TypeDef* dirPort;
uint16_t dirPin;
TIM_TypeDef* pwmTimer;
};Embedded-c-cpp Language Guide
Embedded C/C++ refers to using the C or C++ programming languages for programming embedded systems. These are resource-constrained devices like microcontrollers, IoT devices, automotive controllers, and real-time systems where direct hardware control and performance are critical.
Primary Use Cases
- ▸Microcontroller firmware
- ▸Real-time operating systems (RTOS) tasks
- ▸IoT devices and sensors
- ▸Automotive ECU programming
- ▸Industrial automation and robotics
Notable Features
- ▸Direct memory and register access
- ▸Low-level I/O control and peripheral interfacing
- ▸Deterministic and high-performance execution
- ▸Supports modular and object-oriented designs
- ▸Rich ecosystem of compilers, toolchains, and RTOS libraries
Origin & Creator
C was created by Dennis Ritchie at Bell Labs in the 1970s, and C++ was developed by Bjarne Stroustrup in the 1980s. The embedded variant evolved as developers adapted these languages for low-level, resource-constrained systems.
Industrial Note
Embedded C/C++ dominates industries like automotive (ISO 26262), aerospace (DO-178C), industrial automation, and consumer electronics where memory, speed, and reliability are critical.
