Digital Image Sensors With CMOS

  Adding vision to your projects needs not be a difficult task. Whether its machine vision for robot control or the sampling and storage of images for security, CMOS images sensors can offer many advantages over traditional CCD sensors. Just some of the technical advantages of CMOS sensors are,

Circuit Falcom FSA03 Smart Antenna with uBlox 5 GPS Chipset

The Falcom FSA03 GPS module is an extremely cost effective GPS solution for embedded systems. Retailing for about $50 USD in small quantities, the FSA03 includes an uBlox 5 single chip GPS module integrated with a Sarantel quadrifilar helix antenna to make a tidy single board solution. Official documentation from Falcom indicates the FSA03 has an asynchronous 3.3V serial port for communications using NMEA or UBX binary protocols, a time pulse output and reset input. What the official documentation doesn't indicate is that a USB port and external interrupt pin is routed out but recorded as N.C. (not connected) on the documentation.

 Every USB device must respond to setup packets on the default pipe. The setup packets are used for detection and configuration of the device and carry out common functions such as setting the USB device’s address, requesting a device descriptor or checking the status of a endpoint.

USB Descriptors

All USB devices have a hierarchy of descriptors which describe to the host information such as what the device is, who makes it, what version of USB it supports, how many ways it can be configured, the number of endpoints and their types etc
The more common USB descriptors are

• Device Descriptors
• Configuration Descriptors
• Interface Descriptors
• Endpoint Descriptors
• String Descriptors

Endpoint Types

The Universal Serial Bus specification defines four transfer/endpoint types,

• Control Transfers
• Interrupt Transfers
• Isochronous Transfers
• Bulk Transfers

USB Protocols

Unlike RS-232 and similar serial interfaces where the format of data being sent is not defined, USB is made up of several layers of protocols. While this sounds complicated, don’t give up now. Once you understand what is going on, you really only have to worry about the higher level layers. In fact most USB controller I.C.s will take care of the lower layer, thus making it almost invisible to the end designer.
Each USB transaction consists of a

Connectors

All devices have an upstream connection to the host and all hosts have a downstream connection to the device. Upstream and downstream connectors are not mechanically interchangeable, thus eliminating illegal loopback connections at hubs such as a downstream port connected to a downstream port. There are commonly two types of connectors, called type A and type B which are shown below.

Making sense of the USB standard

Starting out new with USB can be quite daunting. With the USB 2.0 specification at 650 pages one could easily be put off just by the sheer size of the standard. This is only the beginning of a long list of associated standards for USB. There are USB Class Standards such as the HID Class Specification which details the common operation of devices (keyboards, mice etc) falling under the HID (Human Interface Devices) Class - only another 97 pages. If you are designing a USB Host, then you have three Host Controller Interface Standards to choose from. None of these are detailed in the USB 2.0 Spec.

About of MP3 Player

The Bottom Line Quite a few developments have occurred since I've written my two how to choose an MP3 player and CD-MP3 player essays. Time to reevaluate the market!

MP3 player technology has become cheaper with new products and breakthroughs on the horizon. Time to reevaluate the market and consider whether it's time to wait for the new technology or is it okay to buy now?

What's here now?
