Ring-Buffer

A simple ring buffer (circular buffer) designed for embedded systems. It allows creating queues for different types of elements.

Code based on the following two projects:

• http://www.simplyembedded.org/tutorials/interrupt-free-ring-buffer/
• https://github.com/crespum/Ring-Buffer

Usage

#define RING_BUFFER_MAX_NUM_ELEMENTS     16

ring_buffer_t ring_buffer;

uint8_t buffer[RING_BUFFER_MAX_NUM_ELEMENTS];
ring_buffer_attr_t attr = {
    .buffer = buffer,
    .size_elem = sizeof(buffer[0]),
    .num_elem = sizeof(buffer),
};

ring_buffer_init(&ring_buffer, attr);

uint8_t buf_put = 8;
ring_buffer_put(&ring_buffer, &buf_put);

uint8_t buff_get;
ring_buffer_get(&ring_buffer, &buf_get);
printf("buff_get = %u", buf_get); // buff_get = 8
