Wishbone to LPC (Low-Pin Count) Bridge, includes master and slave modules. Supports 8-bit I/O Read and Write cycles, 8-bit Memory Read/Write cycles, DMA cycles, and up to 32-bit Firmware memory read/write cycles. Serial IRQ support is also provided. None of this has been tested (yet) with a third-party LPC Peripheral or Host.

Designing read/write device (RWD) units for industrial RF-Identification applications is strongly facilitated by the NXP Semiconductors HITAG Reader Chip HTRC110. All needed function blocks, like the antenna driver, modulator demodulator and antenna diagnosis unit, are integrated in the HTRC110. Therefore only a minimum number of additional passive components are required for a complete RWD. This Application Note describes how to design an industrial RF-Identification system with the HTRC110. The major focus is dimensioning of the antenna, all other external components including clock and power supply, as well as the demodulation principle and its implementatio

Abstract: This application note explains the hardware of different types of 1-Wire® interfaces and software examples adapted to this hardware with a focus on serial ports. Depending on the types of iButtons required for a project and the type of computer to be used, the most economical interface is easily found. The hardware examples shown are basically two different types: 5V general interface and 12V RS-232 interface. Within the 5V group a common printed circuit board could be used for all circuits described. The variations can be achieved by different populations of components. The same principal is used for the 12V RS-232 interface. The population determines if it is a Read all or a Read/Write all type of interface. There are other possible circuit implementations to create a 1-Wire interface. The circuits described in this application note cover many different configurations. For a custom application, one of the described options can be adapted to meet individual needs.

这是一个比较完整的java语言编写的文件系统程序，有8个基本功能，要求设计一个N个用户的文件系统，每次用户可以保存M个文件，用户在一次运行中只能打开一个文件，对文件必须设置保护措施。且至少有Create,Delete,Open,Read,Write等命令。

Linux系统中，设备驱动程序是操作系统内核的重要组成部分，在 与硬件设备之间 建立了标准的抽象接口。通过这个接口，用户可以像处理普通文件一样，对硬件设 备进行打开(open)、关闭(close)、读写(read/write)等操作。通过分析和设计设 备驱动程序，可以深入理解Linux系统和进行系统开发
