On my last order from SparkFun I threw a Raspberry Pi into the cart to get free shipping just finally had a chance to get it up and running. The whole process was super easy, just used the info found on their site. ( http://www.raspberrypi.org/downloads )
I have not actually tried anything beyond booting and looking around, but the first thing I noticed was silence! I am used to working on desktops or laptops with screaming fans, spinning hard drives and assorted clicking and clanking. When I turned of the machine I used to prepare the SD card for the Pi, there was complete silence and I noticed it almost immediately. I think I like it, but now all I can hear is my keyboard…
I now have the MP3 player hooked up to the Netduino and all of the switches appear to be working. The potentiometer was shot and the rest of them did not function much better. I will need to look into getting replacements.
Luckily I was able to find some code on the Netduino forums and the heavy lifting of getting the Netduino to communicate with the VS1053b over SPI was already completed. They are a great resource, check them out if you have any questions.
