Detailed Description
Structure holding the parameters for TDM initialization.
Member Data Documentation
◆ data_lsb_first
| bool no_os_tdm_init_param::data_lsb_first |
Data ordering (default: msb first)
◆ data_offset
| uint8_t no_os_tdm_init_param::data_offset |
Data offset in a slot, specified in number of bits as offset from MSbit
◆ data_size
| uint8_t no_os_tdm_init_param::data_size |
Useful data size in a slot, specified in number of bits
◆ extra
| void* no_os_tdm_init_param::extra |
TDM extra parameters (platform specific)
◆ fs_active_length
| uint8_t no_os_tdm_init_param::fs_active_length |
Frame sync active length specified in number of bits
◆ fs_active_low
| bool no_os_tdm_init_param::fs_active_low |
Frame sync polarity specifier (default: FS active high)
◆ fs_lastbit
| bool no_os_tdm_init_param::fs_lastbit |
Frame sync is normally asserted on first bit of slot 0 of a frame, this specifier allows assertion on last bit of the previous frame
◆ irq_id
| uint32_t no_os_tdm_init_param::irq_id |
◆ mode
| enum no_os_tdm_mode no_os_tdm_init_param::mode |
TDM operating mode: master/slave, tx/rx
◆ platform_ops
| const struct no_os_tdm_platform_ops* no_os_tdm_init_param::platform_ops |
Platform operation function pointers
◆ rising_edge_sampling
| bool no_os_tdm_init_param::rising_edge_sampling |
Specify whether data sampling occurs on SCK rising edge (default: on SCK falling edge)
◆ rx_complete_callback
| void(* no_os_tdm_init_param::rx_complete_callback) (void *rx_arg) |
DMA receive complete callback
◆ rx_half_complete_callback
| void(* no_os_tdm_init_param::rx_half_complete_callback) (void *rx_arg) |
DMA receive Half complete callback
◆ slots_per_frame
| uint8_t no_os_tdm_init_param::slots_per_frame |
Number of slots in a frame
