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