Today I will show you how easily you can build your first project on blinking LED by using PIC 16 microcontroller. In my previous post Step by step Project guide on PIC Microcontroller I was mansion that for start-up we need
- 1 Proteus 7 Professional (where we Make your hardware arrangement our project and simulate it to see the result)
- 2 Mikcro C. (here we write the Embedded C Program and build the hex file of that)
Start with Proteus
- Click on new file it will open blank work pace.
- Now to make our project we need and add PIC 16, Crystal, Traffic light.
- Now place this on workplace and connect them
Now question is how to do that? For that see the video which will make you understand easily.
Now last and main question is how to write your program?
See in PIC16 four ports are available Port A, Port B, Port C, Port D. Now you have to know the procedure to define those ports as an input or output. For defining ports you can use TRIS command. Let suppose you have to define port D then your command will be TRISD.
Now how to define port D as a input or output for that the format will be
TRISD = 1 (input)
TRISD = 0 (output)
Now see the hardware connection, three LEDs are connected in Port D bit 0, bit 1 and bit 2 positions. So now for glow the
Upper led we have to send 00000001 = 1
Middle LED we need to send 00000010 = 2
Lower LED we need to send 00000100 = 4
So for our Simple Project on LED blinking by PIC 16 Microcontroller we have to send the number Port D =1, Port D= 2 and Port D = 4 with some delay .
