Hello. I have SMARTMP3 Board and NRF52832. The vs1053 works fine on the arduino. But it doesn't work on the nrf52832.
I use these connections:
#define SCK_PIN 3
#define MOSI_PIN 4
#define MISO_PIN 28
#define CS_PIN 24
#define MP3_RESET 27
#define MP3_DREQ 23
#define MP3_XCS 24
#define MP3_XDCS 25 //Data Chip Select / BSYNC Pin
VCC to 3.3V (VDD)
GND to GND
For arduino I use this example https://github.com/ARISGames/arduino/blob/master/MP3_Player_Example/MP3_Player_Example.pde , I have also ported this code to the NRF52832, so they are the same. STATUS register should send me 0x48 value, but I receive only 0, that means it doesn't work. The SD Card (this board also has slot for sd card) works fine.
