4 This is a hardware and software project that includes building and using
6 firmware for user interfacing and/or sensors.  A Butterfly is a $US20
7 battery powered card with an AVR microcontroller and lots of goodies:
8 sensors, LCD, flash, toggle stick, and more.  You can use AVR-GCC to
9 develop firmware for this, and flash it using this adapter cable.
11 You can make this adapter from an old printer cable and solder things
12 directly to the Butterfly.  Or (if you have the parts and skills) you
14 Butterfly and the printer port, or with a better power supply than two
19 SPI protocol drivers interact with the AVR, and could even let the AVR
25 AVR and a DataFlash chip; and to the AVR reset line.  This is all you
26 need to reflash the firmware, and the pins are the standard Atmel "ISP"
40 (a) flash new firmware that disables SPI (set PRR.2, and disable pullups
41 by clearing PORTB.[0-3]); (b) configure the mtd_dataflash driver; and
51 DataFlash in reset) and tweak the spi_butterfly driver to make it bind to
