to run lcd n96 320*240pixle with lpc1768

说明：  FDC2214驱动基于stm32f103ve(Fdc2214 driver FDC2214 driver code based on stm32f103ve)

该程序为数码管静态显示程序。 每按一次 独立按键 中的 T0，数码管的值便会加一(The procedure for the digital static display program. Each time you press the button in the Independent, the value of the digital tube will add a T0)

本文主要是msp430f149为主芯片的电路实验板和完整的汇编源代码。可以直接送厂定做(This article is msp430f149 circuit experiment board based chips and complete compilation of source code. Can be directly sent factory custom)

说明：  方波产生：范围为1~5K，，，精度为100us(Square wave generation: the range of 1 ~ 5K,,, accuracy 100us)

基于STC89C52单片机实现中断LED数码管显示及处理的程序，适合初学值使用(Based STC89C52 MCU interrupt LED digital display and processing procedures, suitable for beginners to use the value)

大多数自行车速度表工作通过使用霍尔效应传感器固定在自行车前叉。磁铁是附加到前轮上的辐条之一,它将与霍尔效应开关一次革命的车轮。速度计监测传感器计数轮革命。如果知道车轮的直径,距离可以很容易地计算如果你知道有多少革命的车轮。此外,如果时间完成革命,平均速度也可以计算出来。 对于这个问题,您将编写一个程序来确定总距离(英里)和平均速度(英里每小时)考虑到车轮直径,革命的数量和总时间的旅行。你可以假定前轮从未离开地面,并没有下滑或打滑。(Most bicycle speedometers work by using a Hall Effect sensor fastened to the front fork of the bicycle. A magnet is attached to one of the spokes on the front wheel so that it will line up with the Hall Effect switch once per revolution of the wheel. The speedometer monitors the sensor to count wheel revolutions. If the diameter of the wheel is known, the distance traveled can be easily be calculated if you know how many revolutions the wheel has made. In addition, if the time it takes to complete the revolutions is known, the average speed can also be calculated. For this problem, you will write a program to determine the total distance traveled (in miles) and the average speed (in Miles Per Hour) given the wheel diameter, the number of revolutions and the total time of the trip. You can assume that the front wheel never leaves the ground, and there is no slipping or skidding.)

YE5852A电荷放大器说明书,在网上找了很久的资料，希望有用。(YE5852A charge amplifier brochures, the Internet looking for a long time, I hope useful.)
