Function
Converts bit information to byte information.
Format
ret = modbus_get_byte_from_bits( src , index , nb_bits )
Parameters
src [ C : uint8_t * ] [ Python : ctypes.POINTER(ctypes.c_uint8) ]
Specify the start address of the array that has stored the bit data which is to be converted to bytes.
index [ C : int ] [ Python : ctypes.c_int ]
Specify the position to start byte conversion in the src array.
nb [ C : uint ] [ Python : ctypes.c_uint ]
Specify the number of bits to convert.
Return values
ret [ C : uint8_t ] [ Python : ctypes.c_uint8 ]
If the function succeeds, the byte conversion result is returned.
Remarks
Converts the given bit information to byte information.
Example
Converts the bit array [0, 1, 0, 1] to byte information (10).
