Introduction.

Workshop PG5 Exercise Chapter 4
Next:
1. Build and donwload the program. (If you need a little help with
building or downloading, refer back to chapter 2).
2. Go on line.
3. Activate the run mode. (refer to chapter 2 for help)
Observing the led’s on your PCD, activate input 0 and input 1. Led 0 and led one
should be on. Also, Output 0 (led 32) should be on.
Turn input 0 and input 1 off, and activate input 2 and input 3. Led 2 and led 3
should be on, but no output leds should be on.
Leave input 2 and input 3 on, and activate input 0 and input 1. Now input led 0,
led 1, led 2, and led 3, should be on, along with output 0 and output 1. (led 32
and led 33)
Binary Inverter:
Using the same program, we will introduce the binary inverter. The binary inverter,
converts the logic 1 or high, to a logic 0 or low, and vice-versa.
1. Deactive the run mode, and go offline.
2. The binary inverter is located on the toolbar of the Fupla editor. The icon is
.
3. Click on the icon and this symbol will be displayed.
4. Position the tip of the arrow where you would like to insert the inverter.
Click the left mouse button one time and this will paste the invert symbol
to the pin. Position the pointer on the symbol and click the left button to
remove the symbol.
Place an inverter symbol to the AND gate of your program to match the display
above. Build and download the program, go online, and activate the run mode. In
the previous exercise, All the inputs had to be high to activate output 1. (Led 33).
Now, input 1, input 2, and input 3 have to be high, and input 0 has to be low, to
activate output 1. (Led 33)
Spend a little time inserting the inverter symbol, creating different scenarios.
Confirm the operation of the different scenarios by testing your programs. You will
find that this symbol is a very useful and commonly used symbol.
Below are a few examples.
