5.12. I2S_Audio_Player

5.12.1. DEMO Purpose

This Demo includes the following functions of GD32 MCU:

 Learn to use I2S module to output audio file

GD32E230C-EVAL board integrates the I2S (Inter-IC Sound) module, and the module

can communicate with external devices using the I2S audio protocol. This Demo mainly

shows how to use the I2S interface of the board for audio output.

5.12.2. DEMO Running Result

Download the program <12_I2S_Audio_Player>. After downloading the program, insert

the earphone into the audio port J1, then listen to the audio file.

5.13. RCU_Clock_Out

5.13.1. DEMO Purpose

This Demo includes the following functions of GD32 MCU:

 Learn to use GPIO control the LED

 Learn to use EXTI to generate external interrupt

 Learn to use the clock output function of RCU

 Learn to communicate with PC by USART
