Hi - I've been searching for the gpio assignments for the lcd pins on the breakout-gs board - I rather rashly soldered a temp/hum sensor on there rather than on the NSSP (which is easy to find) LCLK, BIAS... etc those ones!) cheers Kirk -- Electronics and Computer Science University of Southampton, UK +44 (0)2380 594491 http://www.ecs.soton.ac.uk/~km |

Click on the "Chart" link for the version of gumstix that you have. <http://docswiki.gumstix.com/Gumstix_motherboard_I/O> -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ |

maybe not a good move to have used the LCD pins :-( gum1.ecs.soton.ac.uk now has an SHT75 temp/hum sensor on it - and some code in /root which fails at the mmap stage (to do low-level gpio). We have this working on diferent pins on another gum... feel free to fiddle with gum1 and the temphum.c code as I haven't finished marking exams yet :-) cheers Kirk Dave Hylands wrote: > Hi Kirk, > > On 6/21/07, Kirk Martinez <km...@ec...> wrote: >> Hi - I've been searching for the gpio assignments for the lcd pins on >> the breakout-gs board - I rather rashly soldered a temp/hum sensor on >> there rather than on the NSSP (which is easy to find) >> LCLK, BIAS... etc those ones!) > > Click on the "Chart" link for the version of gumstix that you have. > <http://docswiki.gumstix.com/Gumstix_motherboard_I/O> > -- Electronics and Computer Science University of Southampton, UK +44 (0)2380 594491 http://www.ecs.soton.ac.uk/~km |

The gum1.soton.ac.uk link doesn't resolve. -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ |

Here's my cheat sheet for the breakout board, geared towards the ribbon cables I soldered to it (IDE cable connectors make instant "solderless breadboard" connectors :). The numbers are GPIO port numbers. I probably have one geared towards the 60 pin connector somewhere, too.

oops its gum1.ecs.soton.ac.uk sorry! you can run the binary if you like :-) Dave Hylands wrote: > Hi Kirk, > > On 6/24/07, Kirk Martinez <km...@ec...> wrote: >> maybe not a good move to have used the LCD pins :-( >> gum1.ecs.soton.ac.uk >> now has an SHT75 temp/hum sensor on it - and some code in /root which >> fails at the mmap stage (to do low-level gpio).
