我对 Arduino 电路很陌生，我正在尝试将 DFPlayer Mini 连接到 Arduino Nano BLE 33 Sense。如果我理解正确，库“SoftwareSerial”在 BLE Sense 上不起作用，并且我无法找到使 DFPlayer 正常工作的方法（我也尝试使用 HardwareSerial，但由于某种原因它不起作用） . 你知道有什么方法可以修复连接或找到替换库吗？这是我的代码
#include "Arduino.h"
#include "SoftwareSerial.h"
#include "DFRobotDFPlayerMini.h"
//mp3
SoftwareSerial mySoftwareSerial(12, 11); // RX, TX (meno 11)
DFRobotDFPlayerMini myDFPlayer;
void printDetail(uint8_t type, int value);
void setup(void) {
//mp3
if (!myDFPlayer.begin(mySoftwareSerial)) { //Use softwareSerial to communicate with mp3.
Serial.println(F("Unable to begin:"));
Serial.println(F("1.Please recheck the connection!"));
Serial.println(F("2.Please insert the SD card!"));
while(true);
}
myDFPlayer.setTimeOut(500); //Set serial communictaion time out 500ms
//----Set volume----
myDFPlayer.volume(3);//et volume value (0~30).
myDFPlayer.volumeUp(); //Volume Up
myDFPlayer.volumeDown(); //Volume Down
//----Set device we use SD as default----
myDFPlayer.outputDevice(DFPLAYER_DEVICE_SD);
//----Set different EQ----
myDFPlayer.EQ(DFPLAYER_EQ_NORMAL);
//mp3
static unsigned long timer = millis();
if (millis() - timer > 3000) {
timer = millis();
myDFPlayer.next(); //Play next mp3 every 3 second.
}
if (myDFPlayer.available()) {
printDetail(myDFPlayer.readType(), myDFPlayer.read()); //Print the detail message from DFPlayer to handle different errors and states.
}
// wait for a short amount of time -- sometimes a short delay of 5ms will help
// technically we only need to execute this one time, since we aren't changing the colors but we will build on this structure
//----Mp3 play----
//Play the first mp3
}
void loop(void) {
myDFPlayer.play(1);
}
//Mp3
void printDetail(uint8_t type, int value){
switch (type) {
case TimeOut:
Serial.println(F("Time Out!"));
break;
case WrongStack:
Serial.println(F("Stack Wrong!"));
break;
case DFPlayerCardInserted:
Serial.println(F("Card Inserted!"));
break;
case DFPlayerCardRemoved:
Serial.println(F("Card Removed!"));

case DFPlayerCardOnline:
Serial.println(F("Card Online!"));

case DFPlayerPlayFinished:

Serial.print(value);
Serial.println(F(" Play Finished!"));

case DFPlayerError:
Serial.print(F("DFPlayerError:"));
switch (value) {

Serial.println(F("Card not found"));

Serial.println(F("Get Wrong Stack"));
break;
case CheckSumNotMatch:
Serial.println(F("Check Sum Not Match"));
break;
case FileIndexOut:
Serial.println(F("File Index Out of Bound"));
break;
case FileMismatch:
Serial.println(F("Cannot Find File"));
break;
case Advertise:
Serial.println(F("In Advertise"));
break;
default:
break;
}
break;
default:
break;
}
}
我通过编译得到的错误是这个
