Fc9-comp-macro.png ReadPort
Reads a value to one of the ports with a mask. Configures the masked bits to be inputs before reading the input value. 
Fc9-u8-icon.png - BYTE Port
0=PortA, 1=PortB 
Fc9-u8-icon.png - BYTE Mask
Allows port bits to be modified without effecting other bits, 255 = write full port. 
Fc9-u8-icon.png - BYTE Return


Fc9-comp-macro.png ConfigureInversion
Configures the pin inversion for the two ports. Disabled on all pins by default. 
Fc9-u8-icon.png - BYTE PortA
Port A inversion sent as an 8-bit value, 0 = Disabled, 1 = Enabled 
Fc9-u8-icon.png - BYTE PortB
Port B inversion sent as an 8-bit value, 0 = Disabled, 1 = Enabled 
Fc9-void-icon.png - VOID Return


Fc9-comp-macro.png ReadPortPin
Reads a single port pin from one of the ports. Configures the pins to be an input before reading the input value. Returns 0 or 1 corresponding to the value on the port pin. 
Fc9-u8-icon.png - BYTE Port
0=PortA, 1=PortB

Fc9-comp-macro.png WritePort
Writes a value to one of the ports with a mask. Configures the masked bits to be outputs before writing the output value. 
Fc9-u8-icon.png - BYTE Port
0=PortA, 1=PortB 
Fc9-u8-icon.png - BYTE Mask
Allows port bits to be modified without effecting other bits, 255 = write full port. 
Fc9-u8-icon.png - BYTE Value
Value to write. Range 0-255 
Fc9-void-icon.png - VOID Return


Fc9-comp-macro.png ConfigurePullups
Configures the pullups for the two ports. Disabled on all pins by default. 
Fc9-u8-icon.png - BYTE PortA
Port A pull ups sent as an 8-bit value, 0 = Disabled, 1 = Enabled 
Fc9-u8-icon.png - BYTE PortB
Port B pull ups sent as an 8-bit value, 0 = Disabled, 1 = Enabled 
Fc9-void-icon.png - VOID Return


Fc9-comp-macro.png ReadRegister
Reads an 8-bit value from a register on the I/O expander device. 
Fc9-u8-icon.png - BYTE Address
Register address to write to. Range: 0-15 
Fc9-u8-icon.png - BYTE Return


Fc9-comp-macro.png WriteRegister
Writes an 8-bit value to a register on the I/O expander device. 
Fc9-u8-icon.png - BYTE Address
Register address to write to. Range: 0-15 
Fc9-u8-icon.png - BYTE Value
Value to write. Range: 0-255
