Data logger

A simple data logger with "high speed data acquisition".
A standard SD card formatted with FAT16 was selected as the data storage media because they are cheap, robust, small, and readily interface to a PC. ATMega163 was selected - it has sufficient SRAM for SD card sector reads, a 10 bit eight channel Analogue to Digital Converter (ADC), an SPI interface for an SD card interface and sufficient flash memory to allow development of a FAT16 file system. The chip can be readily replaced, with minimal software changes, to more recent versions of the ATMega range such as the ATMega 16.
