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.

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.
