NVP1918C音频的顺序是怎么弄得。
NVP1918C音频顺序是怎么回事,音频通道始终是乱的。芯片手册上的介绍如下
需要的是4路通道的音频 对应视频通道的5,6,7,8四个通道。但是音频始终存在问题 ,无法把音频第通道改到对应的视频通道代码如下:
void audio_init(unsigned char dec, unsigned char ch_num, unsigned char samplerate, unsigned char bits)
{
gpio_i2c_write(dec, 0xff, 0x01);
if( (dec == 0x60) || (dec == 0x64))
{
gpio_i2c_write(dec, 0x06, 0x1a);
gpio_i2c_write(dec, 0x07, 0x80|(samplerate<<3)|(bits<<2)); //Rec I2C 16K 16bit : master
if(4 == ch_num)
{
gpio_i2c_write(dec, 0x06, 0x1b);
gpio_i2c_write(dec, 0x08, 0x01);
//gpio_i2c_write(dec, 0x0a, 0x45);
//gpio_i2c_write(dec, 0x0e, 0x32);
//gpio_i2c_write(dec, 0x09, 0x03);
//gpio_i2c_write(dec, 0x0e, 0x00);
}
else if(8 == ch_num)
{
gpio_i2c_write(dec, 0x06, 0x1b);
gpio_i2c_write(dec, 0x08, 0x02);
//gpio_i2c_write(dec, 0x0e, 0x54);
//gpio_i2c_write(dec, 0x0f, 0x76);
//gpio_i2c_write(dec, 0x09, 0x07);
//gpio_i2c_write(dec, 0x0e, 0x00);
//gpio_i2c_write(dec, 0x0a, 0x54);//0x54
//gpio_i2c_write(dec, 0x0b, 0x76);//0x76
//gpio_i2c_write(dec, 0x0c, 0x10);
//gpio_i2c_write(dec, 0x0d, 0x32);
}
else if(16 == ch_num)
{
gpio_i2c_write(dec, 0x06, 0x1b);
gpio_i2c_write(dec, 0x08, 0x03);
//gpio_i2c_write(dec, 0x0e, 0x54);
//gpio_i2c_write(dec, 0x0f, 0x76);
//gpio_i2c_write(dec, 0x09, 0x0f);
//gpio_i2c_write(dec, 0x0e, 0x0f);
}
gpio_i2c_write(dec, 0x13, 0x80|(samplerate<<3)|(bits<<2)); // PB I2C 8k 16bit : master
gpio_i2c_write(dec, 0x23, 0x10); // Audio playback out
}
else
{
gpio_i2c_write(dec, 0x06, 0x19);
gpio_i2c_write(dec, 0x07, 0x00|(samplerate<<3)|(bits<<2)); //Rec I2C 16K 16bit : master
gpio_i2c_write(dec, 0x13, 0x00|(samplerate<<3)|(bits<<2)); // PB I2C 8k 16bit : master
}
gpio_i2c_write(dec, 0x00, 0);//add by ssy
gpio_i2c_write(dec,0x09,(gpio_i2c_read(dec,0x09) & 0xf3)
|| 0x40);
gpio_i2c_write(dec, 0x01, 0x88); // Audio input gain init
gpio_i2c_write(dec, 0x02, 0x88);
gpio_i2c_write(dec, 0x03, 0x88);
gpio_i2c_write(dec, 0x04, 0x88);
gpio_i2c_write(dec, 0x05, 0x88);
gpio_i2c_write(dec, 0x22, 0x80); //aogain
gpio_i2c_write(dec, 0x24, 0x14); //set mic_1's data to i2s_sp left channel
gpio_i2c_write(dec, 0x25, 0x15); //set mic_2's data to i2s_sp right channel
