SNAP OEM I/O Systems
Opto 22 SNAP OEM I/O systems are highly configurable, programmable processors intended for OEMs, IT professionals, and others who need to use custom software with Opto 22 SNAP I/O modules.
SNAP OEM I/O Processors
SNAP OEM I/O processors currently include the SNAP-ARL-ASDS, a compact ARM-based unit that mounts on standard Opto 22 SNAP mounting racks and interfaces with a mix of Opto 22 analog and digital SNAP I/O modules. (High-speed hardware counters and latches are not supported for digital I/O.) The brain includes an RS-232 serial port and 10Mbps Ethernet connection, supports multiple file transfer protocols, including FTP and Samba, and comes with an installed Linux kernel and all necessary drivers.
Operating System
The SNAP-ARL-ASDS unit ships with an installed Linux® operating system that is customized to run on the unit's ARM-based hardware. Advanced programmers can use Linux-based tools to develop custom applications for the brain to execute and communicate with the analog and digital I/O modules. The hardware also supports other embedded or runtime operating systems (not provided), allowing developers to use the best combination of OS and programming language for a particular I/O application.
Drivers and Programming
Linux applications running on the SNAP-ARL-ASDS can read and write to analog, simple digital, and serial I/O points on SNAP I/O modules using easily implemented file-based operations. Drivers, code samples, and driver source code are provided. Applications can be developed using several common development tools and environments, including—but not limited to—C or C++, Java, and shell scripts.
Development Tools
For advanced users, Opto 22 provides full Linux and utility source code and comprehensive technical documentation in the SNAP OEM I/O Linux Readme.
