USB Interface Development Board Tutorial -1 STAGE/PART-1 MAKING OF THE MAIN CIRCUIT BOARD CONTROL YOUR DEVICES FROM COMPUTER USING USB PORT – pic18f4550 + MPLAB IDE INTRODUCTION ( USB PROJECT) : STEP 1 This project demonstrates a computer control interface using a USB Board. (USB INTERFACE PROJECT). This tutorial will show you a simple way […]
This project is a USB Generic Human Interface Device (HID) device based on a PIC microcontroller. It is a USB interface for alphanumeric LCD display where the user as desired can program it. USB interface is implemented by using PIC18F2550 microcontroller ideal for low power (nanoWatt) and connectivity applications that benefit from the availability of
USB Indoor/Outdoor Thermometer (or, ‘My first USB device’) This is a simple design that demonstrates the USB peripheral on the PIC 18Fs. There are a bunch of examples for the 18F4550 40 pin chips online, this design demonstrates the smaller 18F2550 28 pin version. The PCB uses surface mount parts, but all components are available

Universal Serial Bus (USB) provides a serial bus standard for connecting a wide variety of devices, including computers, cell phones, game consoles, PDA’s, etc. USB Library contains HID routines that support HID class devices, and also the generic routines that can be used with vendor specified drivers. USB HID Class The HID class consists primarily
This project was sent by Electrical Engineer Atanasios Melimopoulos (Copyright (c) June 15, 2007) INTRODUCTION: In-Circuit-Debuggers, as you may already know, have become the PIC’s debugging standard tool for many programmers because it’s easy use and handy interface to the target picplaced- board. They come with MPLAB plug-ins that provides a full rich set of
The USB keypad reference design demonstrates crystal free USB operation. Microchip has partnered with Lumvatech to demonstrate a low-cost aesthetic design, with touch capability and LED lighting integrated. All features are driven with a single PIC16F1459 MCU. USB is one of the most common serial interfaces used in a wide variety of applications. The USB
In this video we step through a an updated version of the USB demo board. Changes include: -circuit board will only contain bare minimum parts to demonstrate USB communication from host to device and device to host -for both firmware and host software, we will make the projects from scratch, import downloaded USB function libraries,
description Add general purpose input/output lines to your computer based projects. This circuit is a 12 pin digital GPIO interface using the Microchip PIC18f14k50 microcontroller which connects to an USB host port. The microcontroller is available in through-hole DIP20 and SMD packages, too. Circuit diagram The device is powered by the USB bus. 12 port

iButtons are small button like casings that communicate with only 2 wires. They are incredibly robust and all have a unique serial number which is hardware written into the device and never repeated. They are cheap (about 1 Pound / 1,50 Euro/ $2) This serial number allows the keys to be truly unique and thus
In this instructable I’m going to show you how to make your own PIC18 development board that features both Ethernet and Full Speed USB 2.0 at a low cost. Features: The development board is based on a PIC18LF4553 microcontroller. The microcontroller features a Full Speed USB 2.0 (12Mbit/s) interface without the need for any external
