Version 3.20 and higher of THRSim11 contains several components:

LED. This component can be connected to every pin of the simulated 68HC11. The LED will display the current state of the pin. You can choose your own color and title. If you minimize the window you can still see the state of the led.
Switch. This component can be connected to every pin of the simulated 68HC11. The pin can be driven by the switch. You can choose your own color and title.If you minimize the window you can still see the state of the switch. The switch can be toggled by using the system menu. (You enter this menu by clicking the icon.)
7 segment display (with decimal dot). This component can be connected to 8 pins of the simulated 68HC11. Each pin drives one of the segments of the display. You can choose your own color and title.
Hex 7 segment display. This component can be connected to 4 pins of the simulated 68HC11. The state of these 4 pins together is displayed as one hexadecimal digit on the 7 segment display. You can choose your own color and title.
Byte 7 segment display. This component consists of two coupled 7 segment displays. This component can be connected to every internal byte of the simulated 68HC11. E.g. register A, IO register PORTA or memory location $3000. You can choose your own color and title.
Word 7 segment display. This component consists of four coupled 7 segment displays. This component can be connected to every internal word of the simulated 68HC11. E.g. register SP (the stackpointer) or timer register TCNT. You can choose your own color and title.

These components were originally designed by Alex van Rooijen. Alex also designed the way in which the THRSim11 program communicates with these components via the standard windows COM protocols. Harry Broeders did a complete redesign of these components to make them more robust and more friendly to use.

How to use these components:

Install these components as follows:

• Start the THRSim11 program. Remember you must have version 3.20.
• Look in the Connect menu. The components should be added there. See this screenshot.
• When you open a components window you can connect it to the simulated 68HC11 by using the connect dialog. You can enter the connect dialog by:
  • right click your mouse on the component window and select the connect option in the popup menu that will appear.
  • select the component window and select the connect option from the main menu connect option.
  • open the component windows system menu (in Windows 95/98/NT you do this by clicking on the upper left icon of the window) and select the connect option.

  In this screenshot a hexadecimal 7 segment display is being connected to pins PC0, PC1 etc.

• You can not only connect components to pins. The byte 7 segments display for example can be connected to every byte in the simulator. See this screenshot.
