Detailed Description

The main class for the I/O board.


Constructor & Destructor Documentation

GP3::GP3 ( int  rx,
int  tx 
)

Construct a GP3 object with a SoftwareSerial port NOTE: Not available in port version

GP3::GP3 ( Stream &  _port)

Construct a GP3 object with any port Note must be 57600 baud This is the port version's only constructor

GP3::~GP3 ( )

Clean up if using the default port If not using the default port you are on your own.


Member Function Documentation

unsigned int GP3::a2d ( void  )

Get the analog value (0-1023) on the current channel

void GP3::a2dChan ( int  chan)

Select an A/D channel (default=0) All subsequent calls to a2d will use this channel

void GP3::a2dConf ( bool  rightjustify,
int  cselect 
)

Configure A/D convert for right justification (default) and voltage reference Rarely used; see GP3 manual for details

int GP3::getError ( void  )

Returns non-zero if an error has occurred Never automatically cleared after construction

bool GP3::isListening ( )

Call the soft port's isListening function If using your own port, always returns false even if you are using a soft port Not available in the port version

bool GP3::listen ( void  )

Call the soft port's listen function If using your own port, always returns false even if you are using a soft port Not available in the port version

void GP3::pwm ( int  chan,
int  dc,
int  dfreq 
)

Generate PWM Use chan=-1 for hardware channel

int GP3::readByte ( void  )

Read a byte from the GP3 with a timeout You usually do not call this directly Unless you are using repeat

unsigned int GP3::readWord ( void  )

Read a word from the GP3. Rarely called from a user program unless using repeat

void GP3::repeat ( int  count)

The repeat command allows the next command to repeat over and you get the 2nd and later results using readword() or readbyte()

void GP3::setCounter ( int  prescale,
int  ext 
)

Set hardware counter prescaler and source Prescaler can be 1, 2, 4, or 8
