Inspired by this microcontroller audio project [via], I set out to build a 100% DIY digital audio recorder. I chose Texas Instrument's MSP430 microcontroller for this project because it's fast (16 MHz), it's cheap ($1), and it's very low power.

This week we'll look at some MSP430 basics -- power requirements, programming connections, and development tools. In the coming weeks we'll make the MSP430 record audio.

The MSP430 has been around for ages, but the $20 eZ-430 USB development tool has really brought it to the attention of DIY'ers. This is a programmer, debugger, and development board in the shape of a USB flash-drive. If you're lucky, you can get one free at a MSP430 Day in your area.

Read on to learn about basic connections and programming options for the MSP430.

    Note that the programmer/debuggers are not being given away at the events this year, but they are so cheap you can just buy one on ti.com
