libirig106

Forked from Bob Baggerman's irig106lib

libirig106 is a cross-platform open-source library written in C for reading and writing IRIG 106 Chapter 10 (now 11) files. Tested on all 3 major platforms.

A cross-platform Python wrapper is also available.

Using the library

Basic usage consists of:

1. Opening the file
2. Reading a packet header
3. Processing packet data if relevant
4. Repeat from #2

As an example, to iterate over 1553 messages in a file:

I106Status status;
I106C10Header header;
MS1553F1_Message msg;

int fd = open("test.c10", 0);
while (!(status = I106NextHeader(fd, &header))){

    if (header.DataType == I106CH10_DTYPE_1553_FMT_1){  // 0x19

        // Read data into buffer
        int buffer_size = GetDataLength(&header);
        char *buffer = (char *)malloc(buffer_size);
        int read_count = read(fd, buffer, buffer_size);

        // Read CSDW and first message
        status = I106_Decode_First1553F1(&header, buffer, &msg);

        // Step through 1553 messages
        while (!status){
            // Process message...

            // Read next message
            status = I106_Decode_Next1553F1(&msg);
        }

        free(buffer);
    }

    else
        lseek(fd, GetDataLength(&header), SEEK_CUR);
}

Building and Testing (requires cmake)

Unix / make

mkdir build && cd build
cmake ..
make

Windows / visual studio

From the VS native tools commandline run:

mkdir build && cd build
cmake ..
cmake build . --config Release

Alternatively, run the build_and_test.py script from unix terminal or VS commandline to build and then run the test suite.
