I would like to creating a custom add-on library for including the third-party library. The c++ source file in the SmoothLED library includes some overload function operations and function pointer, such as the class smoothLED defined in the header file(SmoothLED.h):
class smoothLED {
/*!
@class smoothLED
@brief Class to allow any Arduino pins to be used with 10-bit PWM
*/
public: // Declare all publicly visible members
smoothLED(); // Class constructor
~smoothLED(); // Class destructor
smoothLED(const smoothLED&) = delete; // disable copy constructor
smoothLED(smoothLED&& led) = delete; // disable move constructor
smoothLED& operator++(); // prefix increment overload
smoothLED operator++(int) = delete; // disallow postfix increment
smoothLED& operator--(); // prefix decrement overload
smoothLED operator--(int) = delete; // disallow postfix decrement
smoothLED& operator+=(const int16_t& value); // addition overload
smoothLED& operator-=(const int16_t& value); // subtraction overload
smoothLED& operator=(const smoothLED& value); // equals overload
smoothLED& operator+(const int16_t& value); // addition overload
smoothLED& operator-(const int16_t& value); // subtraction overload
bool begin(const uint8_t pin, // Initialize a pin for PWM
const bool invert = false); // optionally invert values
void hertz(const uint8_t hertz) const; // Set hertz rate for PWM
static void pwmISR(); // Actual PWM function
static void faderISR(); // Actual fader function
void set(const uint16_t& val, // Set a pin's value
const uint16_t& speed = 0); // optional change speed in milliseconds
private: // declare the private class members
static smoothLED* _firstLink; //!< Static pointer to first instance in list
static uint16_t _counterPWM; //!< loop counter 0-1023 for software PWM
volatile uint8_t* _portRegister{nullptr}; //!< Pointer to the actual PORT{n} Register
smoothLED* _nextLink{nullptr}; //!< Pointer to the next instance in list
uint8_t _registerBitMask{0}; //!< bit mask for the bit used in PORT{n}
volatile uint16_t _currentLevel{0}; //!< Current PWM level 0-1023
volatile uint16_t _currentCIE{0}; //!< Current PWM level from cie table
uint16_t _targetLevel{0}; //!< Target PWM level 0-1023
volatile uint8_t _flags{0}; //!< Status bits, see cpp file for details
uint16_t _changeDelays{0}; //!< Variable storing delay time for fades
volatile int16_t _changeTicker{0}; //!< Countdown timer used in fading
inline void pinOn() const __attribute__((always_inline)); // Turn LED on
inline void pinOff() const __attribute__((always_inline)); // Turn LED off
}; // of class smoothLED //
#endif
I write a wrap function in C++ header file, i.e.,
void createSmoothLED()
{
smLED = new smoothLED();
debugPrint(MSG_smLED_CREATE_SMOOTHLED);
}
But when I connect the Arduino, only one instance of smoothLED can be successfully created. When I create the second instance of smoothLED, MATLAB report an error:
“Unable to receive data from the target hardware. For MATLAB, reconnect the target hardware, clear the hardware objects and try again.”
I want to control RGB LED through the third-party library smoothLED.
So how can I revise my code?
