大型设计中FPGA的多时钟设计策略,很详细的描述了在FPGA设计中时钟设计的方法-FPGA design large multi-clock design strategy, a very detailed description of the FPGA design clock design method

下面是一个超声波测距的程序，硬件电路由于电脑格盘已丢失，下面的代码是从样机上复制的。 硬件电路包括液晶显示、超声波的发射、超声波的接受、滤波、单片机处理。 液晶显示采用LCD1602模块，下面的代码里有液晶的驱动，可以拷贝用于它处。 超声波发射电路包括压电换能器及其支持电路，发射约44KHz的超声波。 超声波的接收电路包含一块CD40106处理芯片。技术指标大约是测距范围在三米左右，测量精度约在厘米级别。大量用于倒车雷达的测距中。-The following is a range of ultrasound procedures, the hardware circuit as a result of the computer grid plate has been lost, the following code is copied from the prototype. Hardware circuit including liquid crystal display, ultrasonic transmitter, ultrasonic acceptance filtering, single-chip processing. LCD1602 LCD module used, the following code, there are LCD drivers, you can use it to copy. Firing circuit including the piezoelectric ultrasonic transducer and its support circuitry, fired about 44KHz ultrasound. Ultrasonic receiver circuit includes a processing chip CD40106. Technical indicators for a range of about 3 meters range around the measurement precision level of about cm. Reversing a large number for the location of the radar.

C51上实现SD卡程序,是FAT32文件系统-C51 realize the SD card procedure is FAT32 file system

一些常用串口的例子，希望对大家有帮助，里面有好几个源代码。-Examples of some commonly used serial port, in the hope that everyone has to help, there are several source code.

这是我的移植中的LPC1768板文件，某些编程文件可以用于指，使用了lwIP的一种方法是没有操作系统（又名“裸机”）上运行 - seeLwIP_with_or_without_an_ OPERATING_SYSTEM。运行在无操作系统模式也经常被称为从控制它的LWIP的符号NOSYS环境。在NOSYS模式下，netconn和插座的API不可用。所有申请必须使用原始（或本地）API编写。至于了lwIP而言，有执行在整个系统中的仅一个线程。由于不需要操作系统模拟层，一个端口这样的环境稍微简单。
