eCosCentric has contributed a generic SPI (serial peripheral interface) bus infrastructure from its eCosPro product line to the public eCos project. The contribution will enable a range of developers support esoteric SPI peripherals using a unified API, the company says.

eCos is a minimalist open source operating system for deeply embedded systems originally developed by Cygnus and later spearheaded by Red Hat (after Red Hat's acquisition of Cygnus). eCos's active developers, including Red Hat and eCosCentric, recently unified eCos copyright holdings under the Free Software Foundation, a move supported by eCosCentric.

The SPI bus is typically used to support external peripherals such as removable multimedia cards, real-time clocks, analog-to-digital converters, and EEPROMS, eCosCentric says. One board that includes an SPI bus is the tiny gumstick-sized DIL/NetPC board that comes bundled with eCos and Redboot.

eCosCentric's contributed SPI bus infrastructure includes target source code and documentation, and is packaged in CDL (component description language). eCosCentric says it is committed to enhancing eCos and fostering its adoption.
