Here's one:

Thanks Dave. Actually I have been trying to build on that website but I am
sort of stuck at the I2C part. It fails when I try to compile the buildroot
using their software, maybe their drivers are designed around an older
buildroot. I get compile errors from missing header files or inconsistent
definitions or structs. I am trying to build my own robotics platform for
school, something like the flockbots, but is it ever challenging :/
Thanks again,
Pete

Yeah - that project was done quite some time ago, and I'm not
surprised with issues in the kernel drivers.

Is there a particular feature of the i2c stuff that you need/want? Or
to put it another way, what is it about the standard i2c srivers
that's not good enough?

Pete,

I'm one of the builders of the Flockbots and may be able to lend a hand.

We used buildroot 773, based on 2.6.11, a very old kernel.  In fact, 773 is
the last version that used 2.6.11.  The I2C stuff included on the wiki
requires 2.6.11 as the ABI was changed in subsequent kernel versions.

As mentioned in previous posts, the wiki is quite old now.  We've made
significant improvements that have yet to be documented to the public.
Including:

- Replaced the Brainstem with a Robostix
- Upgraded to buildroot ~1161 (2.6.15 kernel), including new Linux I2C stack
(allowing Linux to be both I2C Master or Slave)
- Have C-based API for Linux user-space and a Java-based API for easier
(although slower) control and access to all aspects of the Robostix
- Added a 2x16 character LCD for output

If you'd like more info, contact me here or directly at rsteck *at* gmu dot
edu.

Thanks again Randy! I am having great success with my buildroot
compilations.

Hello everyone,

I was wondering if anyone has any information on how to communicate with a
Brainstem GP2 from a Gumstix Verdex pro (with GPSstix and Audiostix 2).
I am using ttyS1 for GPS and ttyS0 for serial comms with my laptop, leaving
ttyS2 free (I think). Is this BTUART??

Thanks for all your help.

Dan

ttyS2 is STUART.
ttyS1 is BTUART
ttyS0 is FFUART

and the verdex has no HWUART.

If you're talking about the onboard GPS (on the gpsstix - I thought it
connected to the STUART port).

See this conversation about HWUART versus BTUART on the gpsstix/audiostix:
