Function Documentation

void serie_closeConnection

(

void

)

Closes the serial port ... if it is open.

Example:

      serie_closeConnection();
   

Definition at line 87 of file serie.cpp.

bool serie_openConnection

(

const char *

port_name

)

Opens a serial port.

Parameters:

port_name

name of the device that provides access to a given serial port

Return values:

	true	if port succesfully openned
	false	if port can not be openned

Example:

      if (serie_openConnection("COM1")) {
            printf("Port openned.");
      } else {
            printf("Error openning the port");
      }
   

Definition at line 41 of file serie.cpp.

int serie_receiveData	(	char *	destination,
		int	max_data
	)

Receives the data that the devices sends to the host.

This functions is non-blocking, so it returns inmediately and no waits if data is not available

Parameters:

	destination	pointer where data buyes will be put
	max_data	maximum number of bytes that can be received, remaing data is keept in device's buffer

Returns:

number of received bytes, or 0 if nothing received

Example:

      unsigned char buffer[10000];
      int num_bytes;

      num_bytes = serie_receiveData(buffer, 10000);
      if (num_bytes > 0) {
            printf("Received %d byes\n", num_bytes);
      }

void serie_sendData	(	const char *	dat,
		int	len
	)

Sends a given number of to the device.

This functions is non-blocking, so it returns inmediately and no waits until data is sent to the device

Parameters:

	dat	pointer to data
	len	number of bytes to be sent

Example:

      unsigned char dades[] = {35,49,110,69};

      serie_sendData(dades, 4);
   

Definition at line 136 of file serie.cpp.

void serie_sendStr

(

const char *

cad

)

Sends strings of text to the device.

This functions is non-blocking, so it returns inmediately and no waits until data is sent to the device

Parameters:

cad

pointer to a null-terminated standard C string

Example:

      serie_sendStr("Les coques amb tomaca estan molt bones\x0D");
