39
40 // 0. Include vsf header file
41 #include "vsf.h"
42
43 // 1. Declare the ring buffer
44 declare_vsf_rng_buf(<ring buffer name>);
45
46 // 2. Defining your ring buffer variable with specific type
47 def_vsf_rng_buf(<ring buffer name>, <item type>)
48
49 // 3. Implement your ring buffer with specific atom access protection macro:
50 implement_vsf_rng_buf(<ring buffer name>, <item type>, <atom access macro>)
51
52 NOTE: You can use vsf_interrupt_safe_simple for interrupt, use __vsf_sched_safe for
53 scheduler, use NO_RNG_BUF_PROTECT for no protection
54
55 // 4. Defining your ring buffer variable
56 VSF_CAL_NO_INIT static <ring buffer name> <ring buffer var>;
57
58 // 5. Initialise a ring buffer with specific ring buffer buffer
59 vsf_rng_buf_init( <ring buffer name>, <item type>, <address of ring buffer var>, <item count>);
60
61 // 6. If you want to initialise a ring buffer with a given buffer, use vsf_rng_buf_prepare
62 rather than vsf_rng_buf_init above:
63 vsf_rng_buf_prepare( <ring buffer name>,
64 <address of ring buffer var>,
65 <address of buffer>,
66 <size of ring buffer buffer> );
67
68 // 7. Use following macro for enqueue, dequeue and peek one item:
69 vsf_rng_buf_send( <ring buffer name>,
70 <address of ring buffer var>,
71 <Item>);
72 vsf_rng_buf_get( <ring buffer name>,
73 <address of ring buffer var>,
74 <address of item buffer>);
75 vsf_rng_buf_peek( <ring buffer name>,
76 <address of ring buffer var>,
77 <address of item pointer>);
78
79 NOTE: Peek returns a reference to existing data in the ring buffer, there is no copy access
80
81 // 8. Use following macro for enqueue, dequeue and peek multiple items:
82 vsf_rng_buf_send( <ring buffer name>,
83 <address of ring buffer var>,
84 <address of item buffer>,
85 <number of Items>);
86 vsf_rng_buf_get( <ring buffer name>,
87 <address of ring buffer var>,
88 <address of item buffer>,
89 <number of Items>);
90 vsf_rng_buf_peek( <ring buffer name>,
91 <address of ring buffer var>,
92 <address of item pointer>,
93 <number of Items>);
94
95 NOTE: Peek returns a reference to existing data in the ring buffer, there is no copy access
96
97 // 9. You can get the number of items within a ring buffer:
98 vsf_rng_buf_count( <ring buffer name>, <address of ring buffer var> )
99
100 // 10. You can get the number of peekable items withi a ring buffer
101 vsf_rng_buf_peekable_count( <ring buffer name>, <address of ring buffer var> )
102
103 // 11. You can reset the peek access
104 vsf_rng_buf_reset_peek( <ring buffer name>, <address of ring buffer var> )
105
106 // 12. You can also remove all peeked items from the queue
107 vsf_rng_buf_get_all_peeked( <ring buffer name>, <address of ring buffer var> )
108
