This project delivers GNU/Linux support (USB driver and Tools) for a Digital Signal Processor (DSP) cards of the Signal Ranger series by SOFT dB, (look here for more details) connected to a GNU/Linux host via USB. The Signal Ranger MK2 is a fixed point DSP board featuring a 300 MHz TMS320C5502 DSP, a 400 kgates SPARTAN 3 FPGA and a high-speed USB 2 interface, providing fast communications to the board (see details on the technical features). The Signal Ranger STD is a fixed point DSP board featuring a 100 MHz TMS320C5402 DSP and a full-speed USB interface (see details on the technical features). The Signal Ranger DSP board series is recognized for its performance and reliability; particularly suitable for a variety of applications, including:

for more examples take a look here. Srange project provides GNU/Linux support for the Signal Ranger Mark 2 (SR-Mk2); it is tested for all linux kernels 2.6.20 and later and to the Signal Ranger SP2 and STD USB kernel module (Linux 2.4.18 and later, 2.6.12 and later are supported).

uLan is multi-master message oriented communication protocol which utilizes RS-485 signal levels. Use of 9-bit character simplifies transfer of binary data. Characters are transferred same way as for RS-232 asynchronous transfer except parity bit, which is used to distinguish between data characters and protocol control information. A physical layer consists of one twisted pair of leads and RS-485 transceivers. Use of 9-bit character simplifies transfer of binary data and for intelligent controllers can lower the CPU load, because of the CPU need not to care about data characters send to other node. Producers of most microcontrollers for embedded applications know that and have implemented 9-bit extension in UARTs of most of today’s MCUs, e.g. some of them are all Intel 8051 and 8096 based MCUs with UART, members of Motorola 683xx family (like 68332, 68376 and so on) and Hitachi H8 microcontrollers. Package ul_drv is the Linux device driver designed to access the uLan network. Today supported hardware is ISA i82510 RS-485 card, support for PCI card equipped by OX16C950-PCI controller or simple active converter dongle for standard PC RS-232 ports. Source tree contains directory containing driver kernel source files, directory with userspace library hiding system dependent kernel driver access routines and some example utilities.

The K8055 interface board, from Velleman, has 5 digital input channels and 8 digital output channels. In addition, there are two analogue inputs and two analogue outputs with 8 bit resolution. The number of inputs/outputs can be further expanded by connecting more (up to a maximum of four) cards to the PC's USB connectors. Here is some features;

...and some specifications;

For this interface board, there are various programs/utilities for GNU/Linux;
