MKR ZERO has an integrated SD connection with special SPI interfaces (SPI1), with which you can play music files without additional hardware! For those who do not know, I2S (Inter-IC Sound) is an electrical serial bus interface standard for connecting digital audio devices.
Attention Musicians: We have some news for you! We have released two libraries for you:
- Arduino Sound Library - an easy way to play and analyze audio data with Arduino on SAM D21-based boards.
- I2S library - for using the I2S protocol on SAMD21-based boards.
Arduino MKR Zero
The MKR ZERO offers you the performance of an Arduino Zero in the smaller format, which is determined by the MKR form factor. The MKR ZERO board is a great tool to learn more about the development of 32-bit applications. It has an integrated SD-connection with special SPI-interfaces (SPI1), with which you can play MUSIC files without additional hardware! The board is operated by Atmel's SAMD21 MCU with a 32-bit ARM Cortex® M0+ Kern.
