Fifo

This module provides a Generic 'type' fifo in pure C. It is not as effecient as a typed fifo, but it provides the flexibity of storing different types and structs.

Fifos can be defined staticly or initiallized dynamicly

dynamic example:

#include "Modules/Utilities/fifo.h"

fifo_t myFifo;

uint16_t myBuf[64];

int main(void)
{
    //creates a fifo that can store 64 uin16_t
    fifo_init(&myFifo, 64, sizeof(uint16_t));

    uint16_t myData = 0;
    for(int i =0; i < 64; i++)
    {
        myData++;
        fifo_push(&myData); //
    }

    fifo_pop_buf(&myFifo, myBuf, 64);

    return 0;
}

static example:

#include "Modules/Utilities/fifo.h"

FIFO_DEF(myFifo, 64, uint16_t); //Expands to:
/*
uint16_t myFifo_data[64];
fifo_t myFifo = {
    .mBuffer = myFifo_data,
    .mHead = 0,
    .mTail = 0,
    .mMaxLen = 64,
    .mCount = 0,
    .mObjSize = sizeof(uin16_t)
};
*/

uint16_t myBuf[64];

int main(void)
{
    uint16_t myData = 0;
    for(int i =0; i < 64; i++)
    {
        myData++;
        fifo_push(&myData); //
    }

    fifo_pop_buf(&myFifo, myBuf, 64);

    return 0;
}

Note

The main benefit of the static define is that it uses an array of 'type' to hold the data. This can help with debugging when the type is a struct.
