PIC18F4550 USB interface

“Implementation of USB-PC Data Transfer Interface with PIC18F4550 Microcontroller” A detailed, useful study about data transfer from the computer’s USB port with PIC18F4550, also features of PIC18F4550, its structure, installation of USB protocol communication circuit are included and the source software is shared. I believe that we will overcome the problem of Turkish resources as we see such successful works.

IMPLEMENTATION OF USB-PC DATA TRANSFER INTERFACE WITH PIC18F4550 MICROCONTROLLER

Developments in the electronics and computer industry require many devices we use in daily life to be faster, more reliable and more useful. For this purpose, small computers defined as microcontrollers are frequently used. The number of computer and microcontroller supported devices is increasing day by day, especially in the field of electronic measurement and instrumentation.

Every computer user frequently uses peripherals such as printers, mice, keyboards, modems, scanners, joysticks and digital cameras. In addition, interface support is seen as an important problem in scientific studies that require computer control. With the introduction of the USB (Universal Serial Bus) protocol into technology, these problems have been significantly reduced.

In this study, the advantages of PIC (Peripheral Interface Controller) microcontrollers over other microcontrollers and the advantages of USB communication over parallel and serial communication are brought together. The basics of the USB protocol, the features and applications of the PIC18F4550 microcontroller used will be discussed in detail.

Purpose and Scope of the Study

The aim of this study is to ensure the fast and safe transfer of data received from peripheral devices to the computer via the USB port, especially in the field of instrumentation. PIC18F4550, one of the PIC microcontrollers produced by Microchip, is a USB-supported microcontroller and was used to process the received signals and send them to the computer via USB. An interface written in the Visual Basic programming language has been established, especially to convert analog signals to digital and present them visually to the user in the computer environment.
Outline of the Study

This work; It consists of five main sections: introduction, theoretical foundations, material and method, application and conclusion. In Chapter 2, information is given about the reasons for choosing USB, the basics of USB protocols, the reasons for choosing the PIC microcontroller, the features of the PIC18F4550 microcontroller and the PIC18F4550 A/D converter module. In Chapter 3, detailed information is given about the hardware and software parts of the programming circuit developed for the PIC18F4550 microcontroller.

Chapter 4 describes the software and hardware configurations prepared for the application. Information is given about the features of the application circuit, programs written in C language, and commands written on the PIC side. In Chapter 5, information is given about some issues regarding the evaluation of the application and the use of the thesis in practice, and finally, thoughts about the development of the application.
