的Arduino在結構

Question

創建結構的數組我有我的代碼如下結構：

struct digitalDataStruct { 
    unsigned long timestamp; 
    int digitalData; 
}; 

struct analogDataStruct { 
    unsigned long timestamp; 
    int analogData[16]; 
}; 

struct structWithPositionAndCo { 
    const int sizeOfDigital = 1000; 
    const int sizeOfAnalog = 10; 
    digitalDataStruct sensorValuesDigital[]; 
    analogDataStruct sensorValuesAnalog[]; 
    int digitalPosition = 0; 
    int analogPosition = 0; 
    int lastDigitalWriteToPC = 0; 
    int lastAnalogWriteToPC = 0; 
}; 

現在我想創建digitalDataStruct和analogDataStruct的陣列。

structPackage.sensorValuesAnalog = new analogDataStruct[structPackage.sizeOfAnalog]; // array to store the value coming from the sensor 
structPackage.sensorValuesDigital = new digitalDataStruct[structPackage.sizeOfDigital]; // array to store the value coming from the sensor 

但我仍然得到這個錯誤：

incompatible types in assignment of 'analogDataStruct*' to 'analogDataStruct [0]' 

任何線索？

您可以使digitalDataStruct和analogDataStruct成員指向這些相應類型而不是數組。您還需要一個成員變量，以便每個成員變量都可以跟蹤每個項目的數量，如果它不是您可以編碼的已知值。

struct structWithPositionAndCo { 
const int sizeOfDigital = 1000; 
const int sizeOfAnalog = 10; 
digitalDataStruct* sensorValuesDigital; 
analogDataStruct* sensorValuesAnalog; 
int digitalPosition = 0; 
int analogPosition = 0; 
int lastDigitalWriteToPC = 0; 
int lastAnalogWriteToPC = 0; 

};
