自制51編程器 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).

VHDL 關于2DFFT設計程序 u scinode1 ∼ scinode9.vhd: Every SCI node RTL vhdl code. The details can be seen in the following section. u 2dfft.vhd: The top module includes these scinodes and form a 3x3 SCI Torus network, and it support these sub-modules scinode1∼ scinode9 reset and clk and global_cnt signals to synchronous the sub-modules to simplify the overall design. u proj2.wfc: VSS simulation result that is the same as the ModelSim simulation result. u Pro2_2.wfc: VSS simulation result of another test pattern can’t cause overflow situation.

VxWorks Device Driver 機制分析.我們不可避免地經常要和device driver打交道,而device driver本身跟操作系統的相關性特別密切,而了解如何能做到屏蔽底層硬件提供標準且通用的接口給上層是我們研究device driver標準的基本目的,由于時間和篇幅的限制,而且我們的工作主要在VxWorks上進行device driver的開發,所以這里只對VxWorks下的標準device driver開發進行分析

WDM(Windows Driver Mode)驅動程序模型。相比起以前的KDM 和VXD 來說,它的性能更高、系統之間移植更加方便。所以,隨著系統的升級(指MS 的操作系統),WDM 已經逐步取代KDM 和VXD,成為MS 系統下驅動程序開發的主流

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.
