Introduction
=================
  This package is an additional sample program to show a usage example 
  that is not presented in the sample program provided in the 
  API-DIO(LNX) development environment.

  Please use it as a reference when using the API-DIO(LNX) development environment.


Specification
=================
  [Supported driver]
  API-DIO(LNX)

  [Supported development languages]
  gcc       (C, C++)
  Python    (3.12)


About this sample
=================
  This is a sample program that additionally implements the I/O switching function
  for devices equipped with the i8255 mode 0 equivalent function, devices equipped
  with the bus master function and other devices that support I/O direction setting
  to the "Input Output Sample [inout]" provided as standard.


Usage
=================
  1. Initialization
   - Specify the device name set in the config as a parameter when executing the sample.
        If parameter is not set, "DIO000" is used.
        Example) ./inout_direction DIO001

  2. I/O direction setting
   <Devices equipped with the i8255 mode 0 equivalent function>
   - To set the 8255 mode, enter 's8' while waiting for command input, 
     then enter the setting value.
   - To get the setting value of 8255 mode, enter 'g8' while waiting for command input, 
     then enter the 8255 chip number.
   - For the values that can be set, please refer to the DioSet8255Mode item in the 
     Function Reference of HELP.

   <Devices equipped with the bus master function>
   - To set the input/output direction, enter 'sd' while waiting for command input, 
     then enter the setting value.
   - To get the input/output direction, enter 'gd' while waiting for command input.
   - For the values that can be set, please refer to the DioDmSetDirection item in the 
     Function Reference of HELP.

   <Other Devices that support I/O direction setting>
   - To set the input/output direction, enter 'si' while waiting for command input, 
     then enter the setting value.
   - To get the input/output direction, enter 'gi' while waiting for command input.
   - For the values that can be set, please refer to the DioSetIoDirection item in the 
     Function Reference of HELP.

  3. Input and Output
   - To test the input, execute 'ip' or 'ib' while waiting for command input.
   - To test the output, execute 'op' or 'ob' while waiting for command input.
   - To get the current output value, execute 'ep' or 'eb' while waiting for command input.

  4. End Processing
   - If you enter 'q' while waiting for command input, the program will exit.
