SPI Xpress USB-Based SPI Host Adapter

SPI Xpress is a Serial Peripheral Interface protocol exerciser and analyzer controlled from PC. It operates on standard SPI and non-standard 4-wires and3-wires serial protocol interfaces up to 50 Mbps data rate.

Serial Peripheral Interface has become a de facto standard for chip-to-chip communication and peripheral control, like real-time clocks, displays, microcontrollers. Its full-duplex and relative simple communication scheme also present many advantages for point-to-point data streaming to DSP, ADC and DAC.

Used as a SPI exerciser and analyzer, this Xpress series device lets you play the role of a master from the PC andlets you intercept the serial protocol traffic for subsequent checking. Moreover, as de facto standard, SPI protocol is characterized by many parameters and custom variations. SPI Xpress offers signal polarity and positioning options, clock generation options and 3 wires port interface capabilities when used as both exerciser and analyzer, enhancing your options for SPI debugging and testing.

Palm-sized, PC-based and USB-powered, SPI Xpress typically fits embedded system development and validations usage scenarios, when there is a need to test and debug at signal level by interacting with each component of a serially-interconnected system.

SPI Xpress is controlled with the 8PI Control Panel software, through the GUI, the TCL/tk scripting interface and the freely provided C/C++ API. SPI analyzer control software notably include 3 levels of decoding and a waveform viewer. Programming interfaces are especially useful when low-level debug must be synchronized with higher-level software debug. Controlling both the software execution and signal-level interactions from the same familiar PC environment also increases software and hardware embedded engineers productivity:

• Stop quitting your desk for trials in the lab;
• Stop waiting for the bench-top logic analyzer or signal generator to be available;
• Place your debug tool next to your laptop on any desk

*** IMPORTANT:  ALL GP and Xpress series devices with serial number starting with "05" must be used with  8PI control Panel software version 2.05 or newer. ***
