[chhsieh3]

• Application: This example code uses the M487 microcontroller and external audio Codec NAU88L25 to decode and play an AMR audio file in a MicroSD card.
• BSP Version: M480_BSP_CMSIS_V3.05.003
• Hardware: NuMaker-PFM-M487 V3.0

This example code uses the M487 microcontroller and external audio Codec NAU88L25 to decode and play an AMR audio file stored in a MicroSD card. Before running the example code, user needs to store the AMR file into a MicroSD card and insert the MicroSD card into the card slot on the NuMaker-PFM-M487 board.

The Play AMR file supports mono mode. The data length is 16 bits and sampling rate is 8 kHz.
