BUG in the WavFilePlayer example
mariocaptain opened this issue · 4 comments
Description
The WavFilePlayer example doesn't work with Teensy 3.5's BUILTIN_SDCARD pin.
SD.begin(BUILTIN_SDCARD) freezes as long as there is any AudioPlaySdWav.play() call in the code.
I have tested with many brand new Teensy 3.5 boards and SD cards.
Also I have tested and can confirm that this problem doesn't happen when an external SPI SD module. In that case, in the below code I just replace BUILTIN_SDCARD with the CS pin connected to the module (8 in my case). So the same code works with an external SD module.
Steps To Reproduce Problem
You can use my code below, which is essentially the stock WavFilePlayer example.
Hardware & Software
Board: Teensy 3.5
Shields / modules used: none
Arduino IDE version: 1.8.9
Teensyduino version: 1.46
Operating system & version: Windows 10
Arduino Sketch
[/C0DE]

This is my code:
Code:
#include <Audio.h>
#include <Wire.h>
#include <SPI.h>
#include <SD.h>
#include <SerialFlash.h>
// GUItool: begin automatically generated code
AudioPlaySdWav playSdWav1; //xy=343.00000381469727,3690.2000064849854
AudioOutputAnalogStereo dacs1; //xy=525.0000076293945,3693.2000064849854
AudioConnection patchCord1(playSdWav1, 0, dacs1, 0);
AudioConnection patchCord2(playSdWav1, 1, dacs1, 1);
// GUItool: end automatically generated code
// Use these with the Teensy 3.5 & 3.6 SD card
#define SDCARD_CS_PIN BUILTIN_SDCARD
#define SDCARD_MOSI_PIN 11 // not actually used
#define SDCARD_SCK_PIN 13 // not actually used
void setup() {
Serial.begin(115200);
AudioMemory(8);
SPI.setMOSI(SDCARD_MOSI_PIN);
SPI.setSCK(SDCARD_SCK_PIN);
if (!(SD.begin(SDCARD_CS_PIN))) {
while (1) {
Serial.println("Unable to access the SD card");
delay(500);
}
}
}
void playFile(const char *filename)
{
Serial.print("Playing file: ");
Serial.println(filename);
playSdWav1.play(filename);
delay(5);
// Simply wait for the file to finish playing.
while (playSdWav1.isPlaying()) {
}
}
void loop() {
playFile("SDTEST1.WAV"); // filenames are always uppercase 8.3 format
delay(3000);
}I'm having the same issue. Switching to a previous version of Arduino and Teensyduino works, seems like the latest version broke something with AudioPlaySdWav.
