[FIFO implementation]
A FIFO instance structure. More...
#include <app_fifo.h>
Data Fields | |
| uint8_t * | p_buf |
| Pointer to FIFO buffer memory. | |
| uint16_t | buf_size_mask |
| Read/write index mask. | |
| volatile uint32_t | read_pos |
| Next read position in the FIFO buffer. | |
| volatile uint32_t | write_pos |
| Next write position in the FIFO buffer. | |
Detailed Description
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.
