Eversmith

A Firmware for ATmega Mircocontrollers (www.atmel.com) to send an receive short messages (SMS) in a GSM Network with a GSM Mobile Phone/Cell Phone/Handy connected to the AVRs serial port. The firmware is completely written in AVR-Assembler Code using AVRStudio4 (free download from the Atmel Web-Site). (You may call it: YAAS - Yet Another AVR SMS Software)

Features:

Sends and receives Short Message in SMS PDU-Format. PDU creation and decoding is done on the fly (from UART to Memory), so only one memory area is needed that can be shared.
Switches output pins on receive of SMS
Send system status via SMS on demand
Sends SMS if input pins where enabled
Menu-based configuration via Terminal-Software
Configuration values are kept in EEPROM storage
Debouncing of input keys
Buffered UART
