Method Detail

close

public void close()
           throws IOException

Close the port of current object

Throws:

IOException - If a TiGPIO error occurs

getPort

public int getPort()

Gets the port id of current object

Returns:

the port id

open

public static TiGPIO open(int portID,
                          int... pinIDs)
                   throws IOException

Open the TiGPIO port by port id and the pin list, and return the object

Parameters:

portID - port id

pinIDs - the pin id use, range:0-15

Returns:

TiGPIO object

Throws:

IOException - If a TiGPIO error occurs

portNumber

public static int portNumber()

Maximum number of port supported

Returns:

number

readPin

public int readPin(int pinID)
            throws IOException

Read the pin level value

Parameters:

pinID - the pin id, range:0-15

Returns:

pin level value, 0:low level, 1:high level

Throws:

IOException - If a TiGPIO error occurs

readPort

public int readPort()
             throws IOException

Read the port value

Returns:

port value, For example: if pinIDs = {0,3,5}, it means pin0, pin3, pin5 are enabled
value=33(0x21):pin0=1, pin1=X, pin2=X, pin3=0, pin4=X, pin5=1, pin6=X, pin7=X, X:ignore

Throws:

IOException - If a TiGPIO error occurs

setEventParameters

                               int evt,
                               int captureFilter)
                        throws IOException

Set the pin event parameters

Parameters:

pinID - pin id, range:0-15

evt - pin event,
EVT_NONE: none event (default)
EVT_RISINGEDGE: rising edge event
EVT_FALLINGEDGE: falling edge event
EVT_BOTHEDGE: both edge event

captureFilter - the event capture filter time window, unit:us

Throws:

IOException - If a TiGPIO error occurs

setWorkMode
