Error Message: pinmap not found for peripheral Location: 0x8009B0B on Nucleo-F429ZI


when I load this onto my board, I get a pinmap not found for peripheral error. I did some research on this problem (One of the pages I visited) and I think I understand the problem, however the pins I'm using all support exactly what I'm asking them to do. This problem has only arisen since I converted my code from procedural to object orientated (I need to do this to implement scheduling properly).

I have a feeling it's to do with how I'm initializing them in the constructor member initialiser list as i don't fully understand how it works (I'm fairly new to C++).

there are other classes to my program however they follow the same structure as my UpdateOutput class.

Thanks in advance for any advice.

int main() {
    printf("inside main");

    DigitalOut led1(LED1);
    AnalogOut Vout(A0);
    UpdateOutput wave;
    SensorData inputs;
    Timer time;

    enum waves {OFF = 0, SINE, TRIANGLE, SAW, SQUARE};
    int waveType = OFF;

    float sonarCorrection = inputs.calibrateSonar();//makes a measurement of the acatual run time of the sonar code
    float topFrequency = 1047.0f;                                       //the highest frequency the synth will play
    float upperSonarThreshold = 1000.0f;                        //the furthest distance the sonar will register
    float lowerSonarThreshold = 100.0f;                         //the closest distance the sonar will measure
    float period = 2272.73f; 
    //replace with:
    //float period = inputs.getFrequency(float lowerThreshold, float upperThreshold, int correction, float topFrequency);
    //after bug fixes have been applied

    led1 = 1;                   //turn on led1 to show code is running properly

    time.reset();
    time.start();
    int tmr = time.read_us();

    //test loop before thredding is applied
    while(true)
    {
        waveType = SINE; //keep synth producing a sine wave for testing
        tmr = time.read_us();
        switch(waveType)
        {
            case OFF:
                Vout = 0.0f;
                break;

            case SINE:
                Vout = wave.sinWave(tmr , period);
                break;

            case TRIANGLE:
                Vout = wave.triangleWave(tmr , period);
                break;

            case SAW:
                    Vout = wave.sawWave(tmr, period);
                break;

            case SQUARE:
                Vout = wave.squareWave(tmr, period);
                break;

            default:
                waveType = TRIANGLE;
                break;


        }//end of wave type switch case
    }

}

Update Output class:

class UpdateOutput{


    public:


            //constructor for class, with member initializer list
                UpdateOutput(): runLed(LED2), clipLed(LED3), dac(D13) 
                {}

            float sinWave(int tmr, float period);

            float sawWave(int tmr, float period);

            float triangleWave(int tmr, float period);

            float squareWave(int tmr, float period);


    private:

    //class attributes
    DigitalOut runLed;
    DigitalOut clipLed;
    AnalogOut dac;

    //extern float frequency(float lowerThreshold, float upperThreshold, int correction);
    bool waveState = 0;
    //float lastVout;
};

example of function within UpdateOutputs class

float UpdateOutput::squareWave(int tmr, float period){
    float Vout = 0.0f;
    //float period5 = period/1.587401052;
    float resultingWave;

    float x = (float)(tmr % (int)period)/period;

    if (x > 0.5f){
        resultingWave = 1.0f;
    }
    else{
        Vout = 0.0f;
    }

    Vout = (resultingWave/WAVE_DEVIDOR)+(0.25f); //translate wave to work between 0 and 1 rather than -1 and 1
    if (Vout > 1){
        clipLed = 1;
        Vout = 1.0f;
    }
    else if (Vout < 0.0f){
        clipLed = 1;
        Vout = 0.0f;
    }
    //printf("Vout = %5.3f\n\r", Vout);
    return Vout;
}//end of squareWave

Solution

  • You are using AnalogOut Vout(A0); as your DAC output in main(). Perhaps you intended to update UpdateOutput::dac directly in the class>

    A0 is assigned PA_3 in PinNames.h while PeripheralPinMaps.h has:

    //*** DAC ***
    
    MSTD_CONSTEXPR_OBJ_11 PinMap PinMap_DAC[] = {
        {PA_4,       DAC_1, STM_PIN_DATA_EXT(STM_MODE_ANALOG, GPIO_NOPULL, 0, 1, 0)}, // DAC_OUT1
        {PA_5,       DAC_1, STM_PIN_DATA_EXT(STM_MODE_ANALOG, GPIO_NOPULL, 0, 2, 0)}, // DAC_OUT2
        {NC, NC, 0}
    };
    

    So it is the AnalogOut Vout(A0); is invalid. D13 assigned to UpdateOutput::dac and which is an alias for PA_5 however is correct.

    You might change AnalogOut Vout(A0) to AnalogOut Vout(D13);, but I suspect that your either are, or intended to update UpdateOutput::dac in the waveform generator functions themselves rather then assigning their return value.
