自制51编程器 I have build my own programmer. This device can program the AT89C51 and works With it. So it can easily be adapted to programming other devices by itself. The Atmel Flash devices are ideal for developing, since they can be reprogrammed easy, often and fast. You need only 1 or 2 devices in low cost plastic case for developing. In contrast you need 10 or more high cost windowed devices if you must develop With EPROM devices (e.g. Phillips 87C751).

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.
