 Step development basic burning programming

Objective :

To learn and understand better how to burn IC.

Content/procedure :

Step 1:

Launch PIC Kit 2 programming software by Selecting Start > Program > Microchip > PIC Kit 2

The following programming interface appears and notifies that the PIC Kit 2 and target device found and connected. 

Step 2: 

If device is successfully detected, the model name will appeared at “Device Configuration Area” 

Step 3 :

For UIC00A, the “VDD Target” will automatically be 5.0. User should powered +5V to the target PIC. 

Step 4 :

Go to File and select Import Hex. Browse for the Hex file location and open to start import the Hex file.

Step 5:

After Hex file has been successfully imported, the target device can be programmed by clicking on Write. The PIC will be erased and programmed with the new Hex code imported. The operation status will display on the Status Window if writing is successful. 

Step 6:

Push button is a special feature to load Hex file into the target device. Push button can be used after Programmer>Write on PIC kit Button is checked as figure below: 

Step 7:

Pressed push button and the Hex file will automatically program into the target device.

Step 8 :

The program already successful Burning Program.

PCB fabrication...hardware step development

Objective :

     PCB Drawing: PCB drawing is designed using Protel DXP 2005. Once the PCB layout has been correctly design, it is now prints out the layout on the A4 size transparent OHP paper. Note that, two types of printers are allowed to print the PCB layout, one is laser printer and the other is carbon type of printer such as Photostat machine. Inkjet and dot matrix type of printer will not work.

Content/procedure :

1.    PCB Cutting: Cut photo PCB size according to the film size.

2.    PCB Photo Etching: Expose the photo PCB in photo etching kit for 8-10minutes.

3.    PCB Developing: Wash the PCB using PCB developer (white powder) for 2 min.

Circuit Connection

Simulation Connection

Result and analysis :

Maxsonar-EZ1

The Maxsonar-EZ1 sensor offer a very short to long range detection which is from 0-inches to 254-inches plus with a very low power consumption. It has provided sonar range information from 6-inches out to 254-inches with 1-inches resolution. Object from 0-inches to 6-inches are range as 6-inches. It has 3 modes selection for the output range which is:

~ Serial, 0V – 5V, 9600 Baud
~ Analog, 10mV/inch
~ Pulse Width, 147us/inch

EUART of PIC16F887

The Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART) module is a serial I/O communication peripheral. It is also known as Serial Communications Interface (SCI). It contains all clock generators, shift registers and data buffers necessary to perform an input or output serial data transfer independently of the device program execution. As its name states, apart from the usage of clock for synchronization, this module can also establish asynchronous connection, which makes it irreplaceable in some applications.

Conclusion :

• Maxsonar-EZ1 will send the output if in ASCII format. For maxsonar-EZ1 sensor, the output are in RS232 format which mean that the HIGH(1) bit are at 0V while the LOW(0) bit are 5V, so need to connect the TX of sensor connect to NPN while RX of sensor to TX of microcontroller as shown in figure above.

Tittle of activity :

• 1st FYP briefing

I'm attending the briefing about FYP at Gemilang Hall, UniKL BMI by FYP Committee about the what to do and not to do. Just like the ordinary briefing like last semester that tell the basic thing and just adding the info about Engineering Day's shirt and the new features like this blog so on.

In this week also I got to meet my project supervisor to discussing about the progress of my project. Basically my project had undergo the simulation development but I just complete half of it. The sensor and camera part still in research in order to combine it with the main micro controller. Futhermore, I had bought some of the components to be used in this project.

14th week ( 23 April 2012 - 27 April 2012 )

Tittle of activity :

• Summit chapter 1,2,3 and progress report

Introduction

The purpose of this project is to research about basically functioning to create new system to reduce accidents that occur during reversing car. The main focus of this project is for the owner of the vehicle especially if the driver is a disable people, they need to install this system to their car. This progress report discusses the progress I have made from Jan 16 – April 27, 2012.

Work Completed from Jan 16 – April 27, 2012

During this period the progress of the project complete in searching information. Much information was get during research using internet and journal. Information about component will be used for this project such as ultrasonic sensor, LCD Display, PIC16F877A, reverse camera system and how the camera will connect to personal computer. The entire component used for this project. From the research found many type of component with same function but different futures and advantages and disadvantages. Beside that the progress for this part is select the PIC will used for this project.

The reason chose the PIC:

        i.            Easily understood by humans.

      ii.            Closer to human language.

    iii.            More simple command and not longer.

During this semester also select the design and shape will be used for this implementation of reverse sensor in vehicle. Must do the best selected of the component to make sure the project will follow the target and archive the objective.

Work to be completed by November 2012

Next, I have to finish my research on the components that will use for this project. This completed on March 2011. For the next step, I have to find all the components needed, start learn about microcontroller language or command so it’s become easy for I’m to start write program and complete the project by applying all the research that I have done before. I also need to finish up my final report for this project but it will only be a few paragraphs due to the lack of information available. I will then write the conclusion and management implications for the final paper. The entire project should be completed by the first week of October 2012.

Problems Encountered

While doing this project research, the first problem that occurs is choosing the suitable sensor for this project, at the same time I also face a problem how to place the camera at the suitable place and it cannot be seen and secure from been stolen. Second problem, is how to write the program. I need someone to teach me about microcontroller, language program and how to re-program with use PIC 16F877A and also refer some book to learns. However the project is still on schedule and will proceed as how the project was planned.

Conclusion

My research project is on schedule and I should encounter no problems finishing it by October 2012. If there is any problem or comment regarding on my final year project, please respond me at hamidahza2509@gmail.com.
