Enum pl_io_port_num contains the list of available 8-bit GPIO ports. Use these constants when selecting the port with the io. object (see the io.portnum property).
Note that GPIO lines are of bidirectionaltype and do not require explicit configuration as outputs or inputs.
Enum pl_io_port_num includes the following constants:
|0- PL_IO_PORT_NUM_0:||8-bit port 0 (P0). Contains I/O lines 0-7. Lines 5-7 are not implemented on this platform.|
