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.

High volume USB 2.0 devices will be designed using ASIC technology with embedded USB 2.0 support.
For full-speed USB devices the operating frequency was low enough to allow data recovery to be handled
in a vendors VHDL code, with the ASIC vendor providing only a simple level translator to meet the USB
signaling requirements. Today s gate arrays operate comfortably between 30 and 60 MHz. With USB 2.0
signaling running at hundreds of MHz, the existing design methodology must change.

For developers who design and program devices that use the USB interface. Introduce the USB
and help to get your devices and communicating as quickly and easily as possible.The USB is versatile enough for a wide range of peripheral devices. Standard peripherals that use USB include mice, keyboards, drives, printers,
and audio/video devices. USB is also suitable for data-acquisition units, control
systems, and other devices with specialized functions, including one-of-a-kind designs.

Supplemental information for a high-speed serial bus that integrates well with most IEEE standard
32-bit and 64-bit parallel buses is specified. It is intended to extend the usefulness of a low-cost interconnect
between external peripherals, IEEE Std 1394-1995. This standard follows the ISO/IEC 13213:1994 Command
and Status Register (CSR) architecture.

Most satellite dish actuators send a series of pulses to indicate their position. By counting pulses the positioner knows where the dish is pointing. It is possible to use a serial port and Linux with RTAI patches in order to count these pulses, thus minimising the external hardware required for a positioner. The zip contains instructions, circuit diagrams and example code.
