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.

SDL Library Documentation. The SDL library is designed to make it easy to write games that run on Linux, *BSD, MacOS, Win32 and BeOS using the various native high-performance media interfaces, (for video, audio, etc) and presenting a single source-code level API to your application. SDL is a fairly low level API, but using it, completely portable applications can be written with a great deal of flexibility.

his project was built and tested with WinAVR-20060125. Make sure the MCU target define in the Makefiles corresponds to the AVR you are using!! To build the code, just install WinAVR and run "make" from the console in echomaster and echoslave subdirs. "make program" will program the device if you have a AVRISP attached. Remember to set the AVR device to at least 8MHz. The AVR may use the programmable clock from MC1319x, just remember to check if the MC1319x and SPI communication is working FIRST! Otherwise you wont get any clock signal to the AVR and then you can t program it or reset the fuses! The MC1319x has default clock output of 32kHz so you will have to set your programmer to a very low frequency (<=32kHz/4) to be able to program it while it is running on that!

describes the most common terms used in radarsystems, such as range, range resolution, Doppler frequency, and coherency. The second part of this chapter develops the radar range equation in many of its forms. This presentation includes the low PRF, high PRF,search, bistatic radar, and radar equation with jamming.

The LM158 series consists of two independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage.

This document describes the uIP TCP/IP stack. The uIP TCP/IP stack is an extremely small implementation of the TCP/IP protocol suite intended for embedded systems running low-end 8 or 16-bit microcon-trollers. The code size and RAM requirements of uIP is an order of magnitude smaller than other generic TCP/IP stacks today.
