Struct stm32_i2s_v12x::format::Data24Frame32

pub struct Data24Frame32;

32 bits transferred for each audio sample, represented in memory with 24 bits per sample

Receiving

When receiving, the 8 least significant bits are ignored. Each received sample will be sign- extended to 32 bits.

Example (I2S, MSB justified, or PCM)

Bits on wire: 1000 1110 1010 1010 0011 0011 xxxx xxxx

Received 32-bit sample in memory: 1111 1111 1000 1110 1010 1010 0011 0011 (0xff8eaa33)

Example (LSB justified)

Bits on wire: xxxx xxxx 1000 1110 1010 1010 0011 0011

Received 32-bit sample in memory: 1111 1111 1000 1110 1010 1010 0011 0011 (0xff8eaa33)

Transmitting

When transmitting, the 8 most significant bits of each 32-bit sample are ignored. The final 8 bits sent on the wire will all be zero.

Example (I2S, MSB justified, or PCM)

32-bit sample in memory: xxxx xxxx 1000 1110 1010 1010 0011 0011 (8 most significant bits can be anything, other 24 bits are 0x8eaa33)

Bits on wire: 1000 1110 1010 1010 0011 0011 0000 0000

Example (LSB justified)

32-bit sample in memory: xxxx xxxx 1000 1110 1010 1010 0011 0011 (8 most significant bits can be anything, other 24 bits are 0x8eaa33)

Bits on wire: 0000 0000 1000 1110 1010 1010 0011 0011
