TMS320c5517的AIC3204声音输出程序设置

3440

问答对人有帮助，内容完整，我也想知道答案 0 目前在做TMS320C5517开发板的测试工作，上面有两个AIC3204模块，现在是想让声音从AIC3204-1的麦克风输入，然后从AIC3204-1和AIC3204-2 的3.5mm耳机接口同时输出，意思就是单通道输入多通道输出。但是ti得测试程序只能单独运行一个AIC3204，也就是单输入单输出，想请各位大神帮帮忙。下面分别是两个AIC3204的测试程序 //AIC3204-1 #define AIC3204_I2C_ADDR 0x18 #include "evm5517.h" #include "evm5517_gpio.h" #include "evm5517_i2c.h" #include "evm5517_i2cgpio.h" #include "stdio.h" extern Int16 aic3204_tone_headphone( );
