how did you set up the SPI control legs? because the example in adafruit is for uno and the teensy has other SPI legs:
#define RESET 17 // VS1053 reset pin (output)
#define CS 10 // VS1053 chip select pin (output)
#define DCS 16 // VS1053 Data/command select pin (output)
#define CARDCS A0 // Card chip select pin
#define DREQ A1 // VS1053 Data request, ideally an Interrupt pin
let me know how that turned out for you.
HI,
Thank you for your fast reply!
I measured the SPI-Clock @ 8 MHz on the teensy 3.1, which might be to high since the max SPI-Clock of the VS1053 is listed @ 5 MHz. Nevertheless, even changing the SPI_CLOCK_DIV in the adafruit lib didn't change much.
To answer your questions:
Pin-Setup on Teensy 3.1:
VS1053-AdafruitBreakout ==> Teensy 3.1
CLK ==> 13
MISO ==> 12
MOSI ==> 11
DREQ ==> 5
CS ==> 20
Reset ==>23
DCS(XDCS) ==> 22
CARDSCS(SDCS) ==> 21
Sourcecode:
I didn't modify much in the end starting from the Adafruit exemple code...
