LOL. Thanks techpaul!

As it turns out, I am now using both! I've got the MCP23017 I/O Expander working via I2C, and a MCP3204 12-bit Analog-to-Digital Converter working via SPI. This will allow me to prototype what I need to for now.

Re: Swap file/partition

Personally, I would only put a swap partition on a physical hard disk, and not attempt to use one with an SD card or a USB drive, unless you were prepared to lose it. For more information: http://www.raspberrypi.org/phpBB3/viewtopic.php?p=39417

Re: Your thoughts on I2C vs SPI

Thanks Grumpy Mike - that makes sense. I think for what I want to do, I2C is the way to go.

Re: Your thoughts on I2C vs SPI

I have already install the latest firmware with Hexxeh rpi-update but I don't know how to install the kernel. I have so much difficulties on how to use the I2C on RPi now. Could you please show me how to install the kernel? All you need to do is download Chris' precompiled and packaged kernel: http...

Your thoughts on I2C vs SPI

There are a lot of discussions online pertaining to the relative merits of I2C over SPI, and vice versa. However, these largely seem to be from the perspective of someone building hardware, rather than simply adding devices to an existing interface. The Raspberry Pi supports both interfaces, so I wo...

Re: Options for development environment

I tried building a new Linux kernel on my Raspberry Pi, and it took almost 19 hours! I have an 8-core Mac Pro which I use for development, having installed a cross compiler toolchain. I also have Ubuntu 12.04 installed under VMWare, which also has a cross compiler toolchain. Both are able to build s...
