Bu devre pic18f4550 mikrodenetleyicisi için tasarlanmış. Devrede pic mikrodenetleyicisi usb bağlantısı sayesinde usb programcılarla programlanabilir ve bu işlem tamamlanınca bağlantı kesilerek usb pinleri ile aynı bağlantı noktasından kontrol yapılabilir. Ayrıca precision soket yardımıyla da diğer pinler rahatlıkla kullanılabilir.

This board is a Microchip PIC prototyping board for the 18F4550 microcontroller using USB. It is designed to have the PIC loaded with a USB bootloader and then a separate programmer is no longer needed. The board has all the circuitry needed for a successful USB interface. Free I/O pins have 1-3 solder pads for easy connection for prototyping. This board is based on the one I use for all my own USB experimentation, and is compatible with the firmware and software in my 18F4550 USB Interface article, my PIC USB Bootloader article, and others. It should also work fine for other PIC USB interfacing projects, such as HID or CDC (virtual COM port) applications.
The board can be populated with a 7805 voltage regulator for use with an external power supply, or can be used directly from USB bus power (up to the current limit of USB), with a 3-pin header that can be used with a jumper to select one mode or the other. The board is made with a mixture of through-hole and surface-mount components, however all of the surface-mount components are resistors or capacitors (only 2 leads), and are the 1206 package size (not microscopic), which are not very hard to solder successfully.

Bu devreyi kurduktan sonra bilgisayara bir program yüklemek gerekli mi seri portu USBden okumak için gibi?

usb ile çalışacaksanız deneme yapacağınız, usb portunu kontol eden program olmalı
