Congratulation, you have succeded with make a LED blink. Now lets improve your skill by making more LED blink ( 8 LED ). In this lesson, we will make four LED blink change reversed.
Step 1st
Build the circuit as shown in figure 1. As you seen on figure 2. P0.0 trough P0.7 is connected to LED's katode each. Remember, that all we want to do with this lesson is make four LED blink change reversed.
Figure 2. Diagram Skematik LED Blink
Step 2nd
In this step, you must tipe the assembly program to make four LED blink, we assume that you have already known the editor, we used MIDE-51 to edit the program.
Step 3rd
Safe your assembly program above, and name it with LED2.asm (for example) Compile the program that you have been save by using MIDE-51, see the software instruction.
Step 4th
Download your hex file ( LED2.hex ) into the microcontroller by using Microcontroller ATMEL ISP software, see the instruction.After download this hex file you'll see the action of the LED ( of course if your cable connection and your program are corrected ).
