I got mine directly from Bas Laarhoven <b...@laarhoven.org>, you might contact him directly and see if he has any on-hand, or if he knows of a good place to buy one. > Also I wonder about pinout usage and other documentation. > Where is the BeBoPr manual that Charles mentioned? > > I could not find any info about their assignments of > the Beaglebone pins. Perhaps one has to read the code > to figure that out. The manual came with the board. I'm not sure I'm allowed to share it, since it's not online anywhere I can find. I have, however, pieced together most of the I/O assignments from a combination of the manual, tracing signals on the board, and examining the software in the git repository. Give me a bit and I'll commit my changes to Michael's repo. ...OK, changes are in the arm335x-hal-pru-module branch, as comments at the bottom of the stepgen.p file: http://git.mah.priv.at/gitweb?p=emc2-dev.git;a=blob;f=configs/pru-examples/stepgen.p;h=d6292075abca1cd687dbb4b47cd1ad748b1521d6;hb=fde5606226ba14d0b033ba6b2310d2c58a296284#l506 This is still a work in-progress, but most of the main pins are there. -- Charles Steinkuehler char...@steinkuehler.net ------------------------------------------------------------------------------ Try New Relic Now & We'll Send You this Cool Shirt New Relic is the only SaaS-based application performance monitoring service that delivers powerful full stack analytics.
