Homepage
This library provides circular buffers. The main difference with other circular buffer libraries is that it does not use dynamic memory allocation for storing data. Instead, the buffer is allocated statically.
Example
#include "mbed.h"
#include "CircularBuffer.h"
int main()
{
CircularBuffer<16> buffer;
uint32_t n = buffer.write((uint8_t*)"Hello World !", strlen("Hello World !"));
printf("wrote %d bytes\n", n);
char str[10];
n = buffer.read((uint8_t*)str, 5);
str[n] = '\0';
printf("str=%s\n", str); // prints:Hello
buffer.read((uint8_t*)str, 1); // discard space
n = buffer.read((uint8_t*)str, 7);
str[n] = '\0';
printf("str=%s\n", str); // prints:World !
return 0;
}
Three types of buffers already exist :
SmallCircularBuffer // 32 bytes MediumCircularBuffer // 128 bytes BigCircularBuffer // 512 bytes
