TIME TO BUILD THE PROGRAMMING

METHODOLOGY

CONTENT:

Now, I need to move to the next step that will help my project really work which is build the programs. After design the schematic diagram especially the brain of the system which is PIC circuit, I can easily determine which pin of the IC that will control each circuit since I have 5 circuit. But, its quite take time to ensure that the program successfully. I have to build the program step by step because I want to try minimize the error while run the program. When the program for one circuit is done, then I will build a program for another circuit and run the program again. By doing this step, I can easily trace any error that will occur while run the program. Because of this step is quite challenging, so I ask my friend that expert about this program to guide me to build a program for my project. I use MPlab to build this program and burn into the PIC 16F877A by using PIC kit 2.

OBJECTIVES:

• To learn about how to build a program for one system.
• To trace any error that occur in the program and how to correct the error until the system successfully done.
• To interface the program to IC then to the hardware.

SCHEMATIC DIAGRAM OF PIC 16F877A

METHODOLOGY

CONTENT:

After changing the block diagram, so I can understand and see clearly what should I do in my project. Then, I decide to design schematic diagram of the main part of my project which is PIC 16F877A by using Protel software. This schematic was design by referring to my new block diagram. Since its quite difficult of designing a circuit and create a programming, so I ask my friend to teach and help me until the function was done successfully. Once the schematic was done, I proceed to the next step which is convert to the PCB layout. By doing this step, it will become easier when I want to print the schematic on the PCB board before etching the board with Ferric III Clorida Acid.But, I need to design another circuit that will connect to this PIC. I will show the design in the next post.

OBJECTIVES:

• To build up the brain of this project..
• To determine each pin that will connected to other circuit by design it using Protel software in order to ensure whether it is successfully function or not..
• To minimize an error that will occur as much as I can..
