I have a bit of a specialized question for you. Recently I got my Pi up and running, and am amazed at what it can pull off. But I want more.
I want to be able to record the output from an accelerometer, which is recording aspects of an impact. To do so I will need a minimum of a 12 bit ADC sampling at 100 kHz. At that speed I figure I will need an external microcontroller to buffer the samples, and then have the Pi read in from the buffer to do all of its fun UI stuff. I am planning on using SPI to let them all chat, but am open to suggestions.
Now the kicker is I can only use DIP packages since I do not have PCB abilities. Could someone suggest a microcontroller and ADC that could handle this? I would prefer if there were no expensive programmers required, gotta love the open source theme with the Pi.
Thanks in advance for the suggestions!
