GENERAL DESCRIPTION

120-PIN CONNECTOR

The high speed ADC SPI program, version 2 and version 3,
(SPIController.exe) allows the user to control advanced features
on high speed, analog-to-digital converters (ADC) with SPI
capability. This advanced controller program is used in con­
junction with the HSC-ADC-EVALB or HSC-ADC-EVALC
data capture boards and specific device evaluation boards to
manipulate and control SPI-accessible features. More infor­
mation on the range of features available can be found in the
specific device data sheets and in the AN-877, Interfacing to
High Speed ADCs via SPI application note.
The SPI Controller program can run as a standalone application
on a Windows® platform, or in conjunction with any available
data analysis tool, such as VisualAnalog™ or ADC Analyzer™.
The software includes advanced features to ensure a smooth
transition from evaluation into prototyping and production.
When a desired configuration is attained, the program includes
a C-code generator that provides compatible C source code that
can be incorporated into customer-developed software. For
users without an available microcontroller, the software also
includes an assembly code generator that produces code
targeted for the ultralow cost PIC12F629 microcontroller.
