-Bitfield Utilities in C
-===========================
-
-This is a C library with functions to help encode and decode Controller Area
-Network (CAN) message payloads or other bitfields.
-
-The header files contain complete function documentation, but to get you
-started, here are examples using the API:
-
-## Bitfield Manipulation
-
-The bitfields are stored in `uint8_t[]`.
-
- uint8_t data[4] = {0x12, 0x34, 0x56, 0x78};
- uint8_t result = get_byte(data, sizeof(data), 0);
- // result = 0x12;
- result = get_nibble(data, sizeof(data), 0);
- // result = 0x1;
- bool success = copy_bits_right_aligned(data, 4, 4, 12, result, 4)
- // success == true
- // result[0] == 0x2
- // result[1] == 0x34
-
-## 8 Byte Helpers
-
-If you are dealing with 8 byte CAN messages as `uint64_t`, there are some
-additional functions prefixed with `eightbyte_` that may be faster or more
-useful.
-
-### 8 Byte Decoding
-
- uint64_t data = 0x8000000000000000;
- uint64_t result = eightbyte_get_bitfield(data, 0, 1, false);
- // result == 0x1
-
- data = 0x0402574d555a0401;
- result = eightbyte_get_bitfield(data, 16, 32, false);
- // result = 0x574d555a;
-
- data = 0x00000000F34DFCFF;
- result = eightbyte_get_byte(data, 0, false);
- //result = 0x0
-
- result = eightbyte_get_byte(data, 4, false);
- //result = 0xF3
-
- result = eightbyte_get_nibble(data, 10, false);
- //result = 0x4;
-
-### 8 Byte Encoding
-
- uint64_t data = 0;
- fail_unless(8byte_set_bitfield(1, 0, 1, &data));
- uint64_t result = eightbyte_get_bitfield(data, 0, 1, false);
- ck_assert_int_eq(result, 0x1);
-
-### CAN Signal Encoding
-
-The library supports encoding floating point CAN signals as well as booleans
-into a uint64_t payload.
-
- uint64_t payload = eightbyte_encode_float(1, 1, 3, 1, 0)
- // payload == 0x1000000000000000
-
- payload = eightbyte_encode_bool(true, 1, 3);
- // payload == 0x1000000000000000
-
-### CAN Signal Decoding
-
-The library supports parsing floating point CAN signals as well as booleans.
-
- uint64_t payload = 0xeb00000000000000;
- float float_result = eightbyte_parse_float(payload,
- 2, // starting bit
- 4, // width of the signal's field
- 1001.0, // transformation factor for the signal value
- -30000.0); // transformation offset for the signal value
- // float_result == -19990.0
-
- bool bool_result = eightbyte_parse_bool(payload,
- 0, // starting bit
- 1, // width of the signal's field
- 1.0, // transformation factor for the signal value
- 0); // transformation offset for the signal value
- // bool_result == true
-
-## Testing
-
-The library includes a test suite that uses the `check` C unit test library. It
-requires the unit testing library `check`.
-
- $ make test
-
-You can also see the test coverage if you have `lcov` installed and the
-`BROWSER` environment variable set to your choice of web browsers:
-
- $ BROWSER=google-chrome-stable make coverage
