3 1. Intrductin The PIC32 Pin Finder applicatin is a utility that helps the develper t fast and accurately find the different pins, cnnectins pints and names in the PIC32 develpment envirnment. This includes the PIC 32 chip itself, the PICtail bus, the Generic USB prttype card and Micrchips Prttype card. The verall view f the applicatin can be seen in figure 1. Signal, pin, functin database Garphical User Interface (GUI) Search & Find Mdule PIC32 Chip pin Identificatin Mdule PIC32 Chip pin Descriptin Mdule PICtail Bus Identificatin Mdule Generic USB Card Pin Identificatin Mdule Micrchip Prttype Card Pin Identificatin Mdule Figure 1, Overall view f the PIC32 Pin Finder The applicatin has a database with all cnnectin infrmatin fr the varius signals, pins and names. The prblem that the develper faces is that there are many signal pins, 100 pins fr the PIC32MX3XXLL chip, mst f the pins has multifunctin capabilities, nt nly that, smetimes the signal fr a certain pin changes name depending if yu lk at the Chip pin, PICtail bus label, test pint cnnectr r prttype card etc. During the develpment phase the develper can put cnsiderable time n finding and identifying different signals n the card under develpment, t get a test pint fr a measurement etc. There is als a risk t using the wrng pin r signal due t mix-ups f signal names, the same signal smetimes changes name. The PIC32 Pin Finder applicatin utility aim is t assist the develper t speed up the wrk and push the flw int a directin f fewer mistakes and therefre higher quality. As a tl t achieve this the applicatin frequently uses pictures with clear markers where t find the different signals. 2. Installatin The PIC32 Pin Finder applicatin is currently nly available and tested under Micrsft Windws XP. It will prbably wrk under W2000 and Windws Vista but it has nt been tested n this perating Systems. T install just duble click the installatin icn and fllw the instructins. The applicatin size is abut 6 mega bytes; the database is abut 2 mega bytes in size. After installatin has been dne yu will have the fllwing applicatin icn under the start menu/spectrn/pic32 Pin Finder: 3. Pic32 Pin Finder Main Frm Select the icn t start the applicatin.

Figure 2, PIC32 Pin Finder Main Frm The main bjects in the Main frm are: Menu Rw, menus t interact with applicatin Main Grid, that shw all signals n the PIC32, chip, PICtail bus, Prt Cards Details, shw details fr the selected rw in the main grid Search, t be able t search fr a specific signal, pin etc. Exit buttn, t exit applicatin Each f the bjects will be described belw in mre detail. Nte that placing the cursr (arrw) ver an item will give a hint abut the bject. Fr example hlding the cursr ver the grid clumn name Pin nr will give the hint text as can be seen in figure 3. Figure 3, Item Hint 3.1 Main Grid The main Grid shws all infrmatin abut the pins and signal names fr the PIC32 chip, PICtail bus, and prttype card. The headers are as fllws: Ref: Database reference fr the rw PIC32 Chip Pin Name: Signal name(s) fr the PIC32 pin Pin Nr: Pin number n the PIC32 Chip PICtail Bus Name: Signal name n the PICtail bus Cn.

The pin number and signal name will be indicated in the left upper crner, in blue. Yu can keep this windw pen and change the selected rw in the main Grid and see hw the indicated pin in red will change t reflect the selected rw in the main grid. If yu click n the Descriptin buttn the applicatin will pen a windw with a descriptin f the selected PIC32 pin. See figure 7 belw. In the Grid in this windw the different functins that the selected pin can have will be shwn. This windw will shw mre infrmatin abut the selected pin: Id: Database reference number Functin: Signal name and functin fr the pin 64Pin: Pin number n a 64 pin PIC32 chip 100Pin: Pin number n a 100 pin PIC32 chip I/O: Type f I/O, see legend at bttm f windw Inp.
