For some reason I cant use the lib on UART1 of an ESP32 module (Doit Devkit V1) using the Arduino IDE and get an error whose reason I dont understand:

This is the error: c:/users/gorkde/appdata/local/arduino15/packages/esp32/tools/xtensa-esp32-elf-gcc/esp-2021r2-patch5-8.4.0/bin/../lib/gcc/xtensa-esp32-elf/8.4.0/../../../../xtensa-esp32-elf/bin/ld.exe: C:\Users\Gorkde\AppData\Local\Temp\arduino\sketches\7E5FE3F65971D37C0376085A1A8B3022\sketch\TEST.ino.cpp.o:(.literal.startup._GLOBAL__sub_I_player+0x4): undefined reference toDY::Player::Player(int, unsigned char, unsigned char)' c:/users/gorkde/appdata/local/arduino15/packages/esp32/tools/xtensa-esp32-elf-gcc/esp-2021r2-patch5-8.4.0/bin/../lib/gcc/xtensa-esp32-elf/8.4.0/../../../../xtensa-esp32-elf/bin/ld.exe: C:\Users\Gorkde\AppData\Local\Temp\arduino\sketches\7E5FE3F65971D37C0376085A1A8B3022\sketch\TEST.ino.cpp.o: in function _GLOBAL__sub_I_player': C:\Users\Gorkde\Documents\Arduino\Sketches\TEST/TEST.ino:4: undefined reference toDY::Player::Player(int, unsigned char, unsigned char)' collect2.exe: error: ld returned 1 exit status

exit status 1

Compilation error: exit status 1`

Here is my minimalized code:

`#include

// Musik initialisieren DY::Player player(1, 33, 25); // Initialise the player on UART1, pins TX: 33, RX: 25.

void setup() { }

void loop() { }`

And my last question: How can I use an already initialised hardwareserial.h port as source for the player?

Solved that by using the arduino lib.

So maybe I thought wrongly before and the ESP code is only for the ESP IDE? Then you should state that clearly so evgerybody understands!

Here is the working code:

`#include

include

//Serielle Schnittstelle2 initialisieren HardwareSerial SerialPort1(1); // use UART1

// Musik initialisieren DY::Player Music(&SerialPort1);

void setup() {

// Serielle Schnittstellen initialisieren Serial.begin(115200); // Serielle Ausgabe an SerialPort1.begin(9600, SERIAL_8N1, 33, 25); // Serielle Schnittstelle 1 für Audio an

// Sound initialisieren Music.begin(); Music.setCycleMode(DY::PlayMode::OneOff); // File einmal abspielen, dann stop }

void loop() { Music.play(); // Musik abspielen Music.next(); // Zum nächsten Titel wechseln } `

SnijderC / dyplayer
