LPC2148 USB Audio Device Example This USB example project implements an USB Audio Device that connects via the USB interface to the PC. It may be used on the following devices: LPC2141 LPC2142 LPC2144 LPC2146 LPC2148 An USB Audio Device (HID) does not require any special USB driver, since the USB Audio support is already built into Windows 2000 and Windows XP. Therefore USB Audio devices can be directly connected to the computer. This example project is designed to work with Keil MCB2140 Evaluation Board. Refer to Running USBAudio for information on how to operate this example project.

The LT® 1529/LT1529-3.3/LT1529-5 are 3A low dropout regulators with micropower quiescent current and shutdown. The devices are capable of supplying 3A of output current with a dropout voltage of 0.6V. Designed for use in battery-powered systems, the low quiescent current, 50mA operating and 16mA in shutdown, make them an ideal choice. The quiescent current is well controlled it does not rise in dropout as it does with many other low dropout PNP regulators.

he LPC932 can be used to create a Pulse Width Modulated PWM signal. That s an analog signal, with only 2 discrete levels, for example 0V and 5V and a constant period. The current value of this signal at a certain poiTnt of time is proportional to its Duty Cycle. That s the High Time during one period divided by the period. It can also be calculated as the average value during a particular period. That means after low pass filtering, (e.g. RC circuit) the signal becomes analog, with an actual value controlled by the microcontroller. The PWM functionality enables the LPC932 to control for example the speed of DC motors or the brightness of electric lighting.
