WEEK 6


3.4.5        Diptrace Design

          DipTrace is EDA software for creating schematic diagrams and printed circuit boards. DipTrace is an advanced PCB design software application that consists of PCB Layout with efficient auto-router, Schematic Capture, Component and Pattern Editors that allow to design own component libraries. Besides being very simple to learn, this software has a very intuitive user interface and many innovative features. For instance, a schematic can be converted to a PCB with one mouse click. Advanced manual placement and auto-placement features allow getting acceptable placement in several minutes. The board designer can instantly renew the PCB from an updated version of schematic and keep all previous work without changes. PCB and Schematic can be compared at any design stage to ensure they are identical.

DipTrace has a powerful automatic router. It can route a single layer and multilayer circuit boards, and there is an option to autoroute a single layer board with jumper wires, if required. Smart manual routing tools allow users to finalize the design and to get the results they want in a blink of an eye. Other important features are Electrical Rule Check ( ERC ), Design Rule Check (DRC) and Net Connectivity Check-the functions that check connections in Schematic by different rules ( pin type or short circuit), the clearance between layout objects, which ensures board accuracy, and connectivity of all nets not depending on how they are connected (with traces, thermals or shapes). 

3.4.5        USB ICSP PIC Programmer V2010 (UIC00B)


                 UIC00B is an enhanced version of UIC00A. It offers low cost yet reliable and user friendly PIC USB programmer solutions for developer, hobbyist as well as students. It is designed to program popular Flash PIC MCU which includes most of the PIC family. Besides 8bit, it can also program 16bit and 32bit PIC MCU. On board ICSPTM (In Circuit Serial Programming) connector offers flexible methods to load program, UART Tool and Logic Tool. It supports on board programming which eliminate the frustration of plug-in and plug-out of PIC MCU. This also allow user to quickly program and debug the source code while the target PIC is on the development board. Since USB port is commonly available and widely used on Laptop and Desktop PC, UIC00B is designed to be plug and play with USB connection. This programmer obtained its power directly from USB connection, thus NO external power supply is required, making it a truly portable programmer. This programmer is ideal for field and general usage. UIC00B offers reliable, high speed programming and free windows interface software.


3.4.5        Design


Before the hardware can be develop, simulation by using Proteus software must be done in order to ensure that the hardware was working properly and successfully function. After this step was completed, the PCB layout for this circuit designed was sketch by the DipTrace simulator. The successful design was printed on the special paper (smooth surface) to transfer it to the board (PCB) by ironing process (heating). The process of etching then will be done by using the acid etching liquid.After the circuit is completely etch, the circuit was tested to ensure that the functionality of the circuit and proceed to the next task of project development.

3.4.8    Hardware development process

A hardware development process is a structure imposed on the development of a hardware product. Synonyms include hardware life cycle and hardware process. PCB designing can be including as part of Hardware development. Figure 3.1 is the model that student use upon hardware completion. Each step describes how student develop the hardware.
3.4              Summary of Chapter

Through internet and library research the reliable source information about the component to use were successfully gathered. So to conclude this chapter, the method that has been use in order to create this device is highly gain the idea to develop this project. In this project methodology, there have two parts which are hardware development and software development. In the hardware development, the block diagram and the main component must be identified. These components are used based on their characteristics which are suitable for the device’s operation. In the software development, the program of device’s operation must be design and coding. Before design and coding the program, the flowchart of operation must be done to make sure the device’s operation is same with the specification
