WM8960问题（有偿，1000元以下）

heyuchen · 发表于 2020-4-27 11:15:36

我用的STM32F429，要求很简单，就是把一段很短的音频文件（18KB）用const内置在程序里面，用软件IIC配置WM8960（配置信息都有），然后再用IIS-DMA形式往WM8960传数据就可以了。但是我编完了程序，死活放不出来。找到问题的麻烦加下我QQ315324320，解决了给1000，谢谢。

const uint16_t data[]={0}; //这里根据需要放音频文件
int main(void)
{
uint32_t wavetotal;
uint32_t i;
wavetotal=sizeof(music)/2;
   NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2);
IIC_Init();
WM8960_Set_Play_Recorde_Reg();
IIS_GPIO_Init();
IIS_Init();
IIS_DMA_Init((uint16_t*)music,wavetotal);
SPI_I2S_DMACmd(SPI2,SPI_I2S_DMAReq_Tx,ENABLE);
DMA_Cmd(DMA1_Stream4,ENABLE);
   I2S_Cmd(SPI2, ENABLE);
}

void  delay_us(uint32_t us)
{
uint32_t i;
    i = us * 20;
    for(; i != 0; i--);

}
