The package makes it possible to create custom SPI buses via GPIO lines. This module is based on i2c-gpio-custom and allows to configure an SPI bus via GPIO lines and expose it to userspace without rebuilding the kernel. This is maily intended to connect microcontrollers and other simple SPI devices without making an ad-hoc kernel driver.

This is the buildsystem for the OpenWrt Linux distribution. Please use "make menuconfig" to configure your appreciated configuration for the toolchain and firmware. You need to have installed gcc, binutils, bzip2, flex, python, perl make, find, grep, diff, unzip, gawk, getopt, libz-dev and libc headers. Run "./scripts/feeds update -a" to get all the latest package definitions defined in feeds.conf / feeds.conf.default respectively and "./scripts/feeds install -a" to install symlinks of all of them into package/feeds/. Use "make menuconfig" to configure your image. Simply running "make" will build your firmware. It will download all sources, build the cross-compile toolchain, the kernel and all choosen applications. You can use "scripts/flashing/flash.sh" for remotely updating your embedded system via tftp. The OpenWrt system is documented in docs/. You will need a LaTeX distribution and the tex4ht package to build the documentation. Type "make -C docs/" to build it. To build your own firmware you need to have access to a Linux, BSD or MacOSX system (case-sensitive filesystem required). Cygwin will not be supported because of the lack of case sensitiveness in the file system. Sunshine! Your OpenWrt Project http://openwrt.org
