Display Keypad Data to LED

In this lesson we are like to design, how to scan keypad 4 x 4, and then display it to LED.

Step 1st
Build the circuit as shown in figure 2.8.2. As you seen on figure 2.2.8. P3.0 trough P3.7 is connected to keypad 4 x 4 and to drive LEDs, it's connected to P2.0 trough P2.7.

Step 2nd
In this step, you must tipe the assembly program to scan your keypad data, we assume that you have already known the editor, we used RIDE-51 to edit the program. ( Download File : exp281.zip )

Step 3rd
Safe your assembly program above, and name it with key1.asm (for example) Compile the program that you have been save by using RIDE-51, see the software instruction.


Step 4th
Download your hex file ( key1.hex ) into the microcontroller by using Microcontroller Laros ATMEL ISP software, see the instruction.After download this hex file you'll see the action of Keypad 4 x 4( of course if your cable connection and your program are corrected )

Display Keypad 4 x 4 with LCD Character 2 x16

After doing lesson 2.8.1. you can see that how easy to scan keypad and read data out to LED. In this lesson it's look like lesson 2.8.2. but the data will read out with LCD Character 2 x16.

Figure 2.8.3.Keypad Connection to Microcontroller

Step 1st
Build the circuit as shown in figure 2.8.3. As you seen on figure 2.8.2 P3.0 trough P3.7 is connected to keypad 4 x 4 and LCD Character 2x16 to read keypad data, connected to P0.0 trough P0.7., P2.0 and P2.1 connected to RS and EN each.

Step 2nd
In this step, you must tipe the assembly program to scan your keypad data, we assume that you have already known the editor, we used RIDE-51 to edit the program. ( Download File : exp282.zip)
