CF2 API ReferencePIOSet -- Configure I/O pin as output and set highDescription:Prototype:Inputs:Returns:Configures an individual bit of an I/O port as an output driving high. The pin argument can bespecified as numerical value between 1 and 50 corresponding to the CF2 pin out on connector C.short PIOSet(short pin);pin is the pin number to act onReturns the current level (after setting) or -1 if there's an errorPIOTestAssertClear -- Return true if I/O pin is currently an output asserting lowDescription:Prototype:Inputs:Returns:This function tests to see if the specified pin is configured as an output and is asserted low.short PIOTestAssertClear (short pin);pin is the pin number to test.Returns nonzero if the pin is set low, and zero if the pin is set high or is not an I/O output.PIOTestAssertSet -- Return true if I/O pin is currently an output asserting highDescription:Prototype:Inputs:Returns:Return TRUE if I/O pin is currently an output asserting highshort PIOTestAssertSet (short pin);pin is the pin number to test.Returns nonzero if the pin is set high, and zero if the pin is set low or is not an I/O output.PIOToggle -- Configure I/O pin as output and toggle current levelDescription:Prototype:Inputs:Returns:Configures an individual bit of an I/O port as an output driving at the opposite of the currentlevel. The pin argument can be specified as numerical value between 1 and 50 corresponding tothe CF2 pin out on connector C.short PIOToggle(short pin);pin is the pin number to act onReturns the current level (after toggling) or -1 if there's an errorPIOWrite -- Configure I/O pin as output and write levelDescription:Prototype:Inputs:Returns:Configures an individual bit of an I/O port as an output driving at the specified level. The pinargument can be specified as numerical value between 1 and 50 corresponding to the CF2 pinout on connector C.short PIOWrite(short pin, short value);pin is the pin number to act onvalue is the value (0 or 1) that you wish to write to the pin.Returns the current level (after setting) or -1 if there's an errorPERSISTORInstruments Inc.34 of 84CF2 API Reference7/19/2005
