Expander_Write_PortA
Expander_Write_PortB
Prototype
sub procedure Expander_Write_PortA(dim ModuleAddress, Data as byte)
Description The function writes byte to Port Expander’s PortA.
Parameters - ModuleAddress: Port Expander hardware address, see schematic at the bottom of this page
- Data: data to be written
Returns Nothing.
Requires Port Expander must be initialized. See Expander_Init.
Port Expander’s PortA should be congured as output. See Expander_Set_DirectionPortA and
Expander_Set_DirectionPortAB routines.
Example
‘ Write a byte to Port Expander’s PORTA
...
Expander_Set_DirectionPortA(0,$00) ‘ set expander’s porta to be output
...
Expander_Write_PortA(0, $AA)
Notes None.
