Hi all, I am having problems integrating robostix gumstix at this moment. I have fixed a 10k pull-up resistor between pin 3 and 4 of gumstix connector on robostix as in the below mentioned link. http://docwiki.gumstix.org/index.php/Robostix_modifications. but my gumstix is not able to boot even with these modification. previously when i connected tweener and gumstix i was able to discover the blutooth device on gumstix on my laptop but now when i use just the robostix and gumstix i don't discover the blutooth device on gumstix which means that the gumstix is not booting up. Can anyone suggest me the right way to do this stuff ? Thanks, |

I had the same problem before. My set kept rebooting. Somebody sent me a link showing how to connect "UARTS Pin14"(AtmelI2C-V) to "BOARD Pin+"(edge side) on Robostix. I couldn't find the link, but just try it and see if it work. For the worst case, you can always use 2 power supplies, one for Gumstix, one for Robostix? -- View this message in context: http://www.nabble.com/Robostix%2BGumstix-Connecton--tp16647495p16656668.html Sent from the Gumstix mailing list archive at Nabble.com. |

Thanks for the reply... Could you please explain what you mean by "BOARD Pin+"(edge side) on Robostix Do you mean; +5v or what? And besides how possible is it to power Robostix and Gumstix simultaneously? Can we power verdex from tweener and power robsotix at thesame time with all three connected to each other?

There are 2 pins right next to the power jack on Robostix. If you look carefully, you can see "BOARD" , (on mine, it just show"ARD" and the "BO" was cut). You can supply the Robostix through these pins too. I guess that why it was right next to the power jack. The "BOARD Pin+" is pin near the edge. Yes, it means +5V. If you can, you can search for the layout map of the Robostix. I forgot where did I find them, so I can not send you the link, sorry! Once you done this, you don't have to worry about the double power supplies. Sorry for my MISTAKE. What I tried to say is use 2 power supplies for Robostix and Wifistix simultaneously? There is a power jack on my Wifistix, just like the one on Robostix. With one power supply connect to the Robostix, the Gumstix would be turn on but not enough power to make it functional. I guess that's why my set kept rebooting. Once I plug 2 power supply, the problem solved. Seems like the power from Wifistix support Gumstix too. 2 supplies did not burn out my set, so I assume it should be safe. The connection I mention above can solve this issue too, but require you have a soldering iron. I don't have Tweener, so I can not prove that, but my Robostix+Gumstix+Wifistix work fine. I hope I explained your question. -- View this message in context: http://www.nabble.com/Robostix%2BGumstix-Connecton--tp16647495p16664696.html Sent from the Gumstix mailing list archive at Nabble.com. |

Yes it worked! Thanks Hanguang. Presently working on howto program robostix with an analog to digital converter.
