The 700 mA supply might be marginal (just from what I've read), but I've been having similar problems. I'll start another thread for my problems, assuming I don't first find a thread that matches completely, but here's some info on my problems: 5VDC phone charger power supply, rated at 1000 mA with ...

<t>I'm a driver guy from the I2C thread mentioned earlier and must admit I haven't looked at my driver code for at least a week.  I'm in the same boat as others here in that I don't have a Pi ... my order might go through by the end of June, but who knows.  The driver task looks fairly straight-forw...

<t>Is there anyone already working on developing a driver for the Broadcom BSC?  I'm looking into morphing an existing i2c driver into one to support the BSC and while it doesn't look like an onerous task, but I'd hate to spend time on redundant work.<br/> <br/> If I am the only one looking at this ...

<t>It's been a matter of (somewhat bad) news in the kernel community that with the proliferation of ARM devices implementing Linux OE's, each within their own realm, getting patches to the kernel has been problematic.  Some because of platform issues, leading to questions like "do we need this in th...

<t>mistertransistor said: <br/> <br/> <br/> <br/> Anyone else wanting to use I2C devices?<br/> <br/> Andrew<br/> <br/> <br/> Oh, yes.  Sparkfun (and others, I"m sure) have some nice, small accelerometers, electronic gyros and other sensor modules for sale (big in the Arduino arena) that talk via I2C...

<t>Not SDR related, but still ham related: I'm kicking around using the R-Pi in an FRS/GPRS radio hack where I hijack the existing tuner-IC-to-microcontroller serial link (among other signals) to wind up with a programmable radio for at least the 70 cm band.  Granted, applying a microcontroller to t...
