Raspberry Pi Pico WAV Player oleh Elehobica

4 Apr, 2022

Di post sebelumnya, Loresek membagikan preview proyek Digital Music Player berbasis Raspberry Pi Pico. Nah proyek ini berdasarkan pada proyek RPi_Pico_WAV_Player nya Elehobica.

Raspberry Pi Pico WAV Player oleh Elehobica

Untuk spesifikasi nya sendiri bisa dilihat di bawah ini:

Playback for 44.1KHz 16bit Stereo WAV format
SD Card interface (exFAT supported)
160x80 LCD display
UI Control by 3 GPIO buttons or Headphone Remote Control Buttons
Display Tag information by LIST chunk in WAV File
Display Coverart image by JPEG file
Volume Control Function by fully utilizing 32bit DAC range

Untuk ukuran sebuah proyek DIY DAP spesifikasi di atas sudah cukup lengkap, walau Playback hanya bisa memutar file WAV 16bit / 44.1KHz tapi bagi Loresek ini udah cukup untuk menikmati alunan musik-musik favorit.

HARDWARE

Bagian terpenting untuk membuat proyek DIY Audio khusunya audio portable adalah hardware-nya. pertama apakah mudah untuk ditemukan di pasaran? dan kedua apakah harga-nya terjangkau? Yup!!! semuanya masuk kriteria kriteria proyek DIY.

Hardware minimal yang dibutuhkan untuk membuat proyek Raspberry Pi Pico WAV Player ini antara lain:

Modul Raspberry Pi Pico.
Modul LCD SPI dengan driver ST7735S dan resolusinya adalah 160x80 Pixel.
Modul DAC, pada contoh menggunakan modul PCM 5102.
Modul Soket Micro SD.
Tombol tekan (push button) sebagai controlnya.

Sofware/ Firmware Raspberry Pi Pico WAV Player

Elehobica menyediakan source firmware-nya secara terbuka melalui laman Githubnya (lihat akhir artikel).
