Implementation USB into microcontroller Igor Atmel-USB device:
USB-RS232 converter + USB-8/16bit converter + USB-EEPROM scratch pad
based on cheap AVR microcontroller
Purpose of this article is to inform readers about implementation USB to RS232 converter into singlechip microcontroller, which this interface directly not supports. Simply: implementation USB interface on firmware level (similar as emulation of RS232 interface in microcontrollers, which not have RS232 support). Given project is the next follower of my project of basic USB module IgorPlug-USB (AVR) (computer remote control IgorPlug with USB).
For use in user applications I developed improved USB to RS232 converter (+ another interfaces) with next features:
Device is intended for embedding into your products (source codes of firmware and software is free). For better choice I have prepared two versions, which are different in used processor type. Simpler version is based on AT90S2313 processor. Improved version is based on ATmega8.
