@brief I2S slot configuration for tdm mode
Fields§
§data_bit_width: i2s_data_bit_width_t
< I2S sample data bit width (valid data bits per sample)
slot_bit_width: i2s_slot_bit_width_t
< I2S slot bit width (total bits per slot)
slot_mode: i2s_slot_mode_t
< Set mono or stereo mode with I2S_SLOT_MODE_MONO or I2S_SLOT_MODE_STEREO
slot_mask: i2s_tdm_slot_mask_t
< Slot mask. Activating slots by setting 1 to corresponding bits. When the activated slots is not consecutive, those data in inactivated slots will be ignored
ws_width: u32
< WS signal width (i.e. the number of bclk ticks that ws signal is high)
ws_pol: bool
< WS signal polarity, set true to enable high lever first
bit_shift: bool
< Set true to enable bit shift in Philips mode
left_align: bool
< Set true to enable left alignment
big_endian: bool
< Set true to enable big endian
bit_order_lsb: bool
< Set true to enable lsb first
skip_mask: bool
< Set true to enable skip mask. If it is enabled, only the data of the enabled channels will be sent, otherwise all data stored in DMA TX buffer will be sent
total_slot: u32
< I2S total number of slots. If it is smaller than the biggest activated channel number, it will be set to this number automatically.
