A FIFO instance structure. Keeps track of which bytes to read and write next. Also it keeps the information about which memory is allocated for the buffer and its size. This needs to be initialized by app_fifo_init() before use. More...

uint16_t app_fifo_t::buf_size_mask |
Read/write index mask. Also used for size checking.
uint8_t* app_fifo_t::p_buf |
Pointer to FIFO buffer memory.
volatile uint32_t app_fifo_t::read_pos |
Next read position in the FIFO buffer.
volatile uint32_t app_fifo_t::write_pos |
Next write position in the FIFO buffer.
