For a recent project, I needed to boost the output from a USB (high ampage charging) port from 5V up to 18V to power an amplified speaker. I decided to try rolling my own boost converter (mainly because playing with big inductors sounded cool). My first attempt was a dismal failure (it could only source about 10mA […]

Abstract: USB has just become easy to implement. This application note eases equipment designers into USB by allowing them to continue to transmit and receive data using the familiar UART frames of the MAX3100 UART. A UART-to-USB converter IC and operating system driver will take care of all of the USB complexity. The application note describes
Desription ROHM’s USB Audio Decoder ICs integrate a USB 2.0 host, SD memory card controller, AAC decoder, WMA decoder, MP3 decoder, Audio DAC amp, and a system controller all on a single chip, allowing easy playback of music stored in USB flash memory using an audio player. They can be easily added to virtually any
Introduction USB is very common interface today. If you look around, many of devices today comes with a USB port. Computers, printers, routers, usb keys, etc. All this devices have a USB controller inside. These devices can be divided in two groups: USB Host (like a computer, routers, modern LCD TV’s); USB Device (like flash
Here is an example of how to interface a PIC18F452 to a PC via the USB port. The windows-pc (98, Me, 2000, XP, 2003) runs a program (C# application, Microsoft Visual Studio .NET 2003) to communicate with the USB interface, which transfers data to and from the PIC18F452.

Introduction If you’ve dabbled with PIC18F microcontrollers and the USB Generic HID standard before (perhaps you’ve even tried my Building a PIC18F USB device project) then you will have noticed that there is a lot of complexity in supporting USB on both the PIC18F and the Windows host-side of things. Getting beyond the basic steps of

INTRODUCTION The idea for creating a USB sound card based on a PIC came from discussions of other people creating one on the Microchip USB forum. The hardware of the card is based on all Microchip products. The software uses a modified version of the Microchip USB framework which is interrupt driven instead of the

Inroduction More and more experiments are now ‘PC-assisted.’ Also conventional acquisition systems are very expensive. Since portable PCs are today common and a USB link is a better solutionhere we present an oscilloscope using USB port of the PC that operates at up to 10 kHz with ±16V input voltage. It has much more improved features than the PC-based oscilloscope . The oscilloscope uses IC
