Arduino 开发的 CH32V307 IIS 音频输出测试

[复制链接]
这次介绍的是如何在CH32V307上通过Arduino 编程，从 IIS接口输出一个正弦波然后通过NS4168 播放出来。关于NS4168的介绍，可以在【参考1】看到。
线路方面：
B12（I2S2_WS）连接到 LRCLK
B13（I2S2_CK） 连接到 BCKL
B15（I2S2_SD）连接到  SDAT
同时特别提醒 NS4168 的CTRL 需要连接 3.3V
之后，给Ch32v307烧录如下代码：
  1. //#include "ch32v30x_spi.h"

  2. /* Global Variable */

  3. #define  Len    48*16*2

  4. u16 I2S2_Tx[Len] = {

I2S2_Tx 里面定义的是一个正弦波数据，通过如下C# 代码生成：
  1. using System;

  2. using System.Collections.Generic;

  3. using System.Linq;

  4. using System.Text;

  5. using System.Threading.Tasks;

  6. 

  7. 

  8. namespace SinAudio

  9. {

  10.     class Program

  11.     {

  12.         public const int LOOPS = 16;

  13. 

  14.         static void Main(string[] args)

  15.         {

  16.             double sin,cos;

  17.             for (int i = 0; i < LOOPS * 48; i++) {

  18.                 sin = (0.5 + Math.Sin(i * 2 * 3.1415 / 48))* 65535/2;

  19.                 //cos = (0.5 + Math.Cos(i * 2 * 3.1415 / 48)) * 65535 / 2;

  20.                 Console.Write("{0},{1},", (Int16)sin, (Int16)sin);// (Int16)() * );

  21.                 if (i % 32 == 0) {

  22.                     Console.WriteLine("");

  23.                 }

数据可以看成是 48K 16Bits 采样结果，数据是int16 (负数使用补码形式表示)
