At the moment we are experimenting microcontroller sometimes we have some constraints either in the program or in the hardware, there will be two possible problems:<\/span> 3. The combination of both<\/span><\/p>\n To overcome this, we must localize Which one of our microcontroller system if the program or hardware?.<\/span> To view the program’s true or not, we have already made in software Mide, when in the build if no error means that the program that we have made are correct, then compiled to hex.<\/span> That’s why before we download the program into the microcontroller then it is good we simulate beforehand.<\/span><\/p>\n One simulation software that will be introduced is ISIS Proteus software.<\/span> Advantages of this software we can draw the circuit and simulate it.<\/span><\/p>\n Figure 39 display the ISIS 7 at the time will be installed<\/span><\/p>\n \uf076 the simulation software used is PROTEUS ISIS 7 Professional.<\/span> Following initial appearance<\/span><\/p>\n Figure 40 initial appearance ISIS 7 l<\/span><\/p>\n \uf076 Can select Component mode image sepert 1:40.<\/span><\/p>\n Figure 41 display Tool Box ISIS 7<\/span><\/p>\n \uf076 Then select the components to be used, see picture.<\/span> In the toolbox to the left, select Component mode and then click the button that contains the letter P To enable Pick Device.<\/span> Pick Device is a dialog box to select the components that we will use.<\/span><\/p>\n Figure 42 Display select components<\/span><\/p>\n \uf076 Example: will create an image microcontroller circuit with LED display components chosen are: 8031, AT89C51, red LED, resistor.<\/span><\/p>\n Figure 43 List of components to be assembled.<\/span><\/p>\n \uf076 Display after coupled with some LED<\/span><\/p>\n
