AVR325: High-Speed Interface to Host EPP Parallel Port
Updated: Feb 24, 2005
Description
This Application Note describes a method for high-speed bidirectional data transfer between an AVR Microcontroller and an of-the-shelf IBM (R) PC-compatible desktop computer. The interface provides an 8-bit parallel data path, yielding data transfer rates up to 60 kilobytes/second with an AVR processor operating at 4 MHz. This is an order of magnitude faster than a standard RS-232 connection while not requiring complex external interface hardware (like USB or SCSI).
