Functions
	EV3_VAR_INIT (char *ev3_brick_addr, NULL)
	Predefined IP address of the EV3 brick.
	EV3_VAR_INIT (uint16_t ev3_brick_port, 8800)
	UDP port of the EV3 brick.
int	ev3_init (void)
	Initialize the remote access and detect the EV3 brick. This function do nothing in the case of the local access. To disable the brick detection just specify IP address before the call of this function. More...
void	ev3_uninit (void)
	Uninitialize the remote access.
size_t	ev3_write_binary (const char *fn, char *data, size_t sz)
	Write binary data into the specified file of the EV3 brick. More...
size_t	ev3_write (const char *fn, char *value)
	Write a string into the specified file. More...
size_t	ev3_write_bool (const char *fn, bool value)
	Write a boolean value into the specified file. More...
size_t	ev3_write_int (const char *fn, int value)
	Write an integer value into the specified file. More...
size_t	ev3_write_dword (const char *fn, uint32_t value)
	Write an unsigned integer value into the specified file. More...
size_t	ev3_write_byte (const char *fn, uint8_t value)
	Write a byte value into the specified file. More...
size_t	ev3_write_float (const char *fn, float value)
	Write a float value into the specified file. More...
size_t	ev3_write_char_array (const char *fn, char *value)

size_t	ev3_multi_write_binary (uint8_t *sn, uint16_t pos, const char *fn, char *data, size_t sz)
	Write binary data into several specified files of the EV3 brick. More...
size_t	ev3_multi_write (uint8_t *sn, uint16_t pos, const char *fn, char *value)
