Hi, My question for everyone is does anyone have a way to sigle out and use the 4 GPIO pins on the GPS daughter board. I have the connex mother board. I have the pinout for the 60 pin hirose. I just don't know how to talk to only the 4 GPIO pins. Thanks Jana |

The ones attached to the gumstix are easier to use than the ones attached to the UCB1400. -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ |

Hey Dave thanks, How do I access any of the pins individually. I just want to tie them to turn on 4 different leds in different sequences. -Jana On Fri, Apr 11, 2008 at 1:14 PM, Dave Hylands <dhy...@gm...> wrote: > HI Jana, > > > My question for everyone is does anyone have a way to sigle out and use > the > > 4 GPIO pins on the GPS daughter board.

Once you figure out the GPIO number you can do: modprobe proc_gpio echo "GPIO out set" > /proc/gpio/GPIO99 (replace 99 with the GPIO pin number) Replace "set" with "clear" to change the output to be low. You might also want to try: <http://docswiki.gumstix.com/index.php/Sample_code/C/gpregs> but replace #ifdef __ARM_EABI__ 0x40E00000 / MAP_SIZE #else 0x40E00000 & ~MAP_MASK #endif with 0x40E00000 & ~MAP_MASK -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ |

Thanks a lot I will give it a try. -Jana On Sat, Apr 12, 2008 at 7:04 PM, Dave Hylands <dhy...@gm...> wrote: > Hi Jana, > > On Sat, Apr 12, 2008 at 4:46 PM, Jana Coakley <ja...@ag...> > wrote: > > Hey Dave thanks, > > How do I access any of the pins individually.
