Gestalt Firmware Library Reference

Reserved Microcontroller Resources

Memory Resources

• SRAM: 640 bytes. This leaves 1408 bytes remaining on an Atmega328.
• EEPROM: Addresses 0, 1 and 2.
• Program Memory: 2250 bytes. Approx 7% of avaliable on Atmega328.

I/O

• USART0 Tx and Rx pins. PD0 and PD1 on Atmega328.
• Networked Gestalt: three pins for an LED, pushbutton, and transciever enable. These are user-assignable.
• Arduino: The LED on Digital I/O 13 (PB5) is automatically configured as an output. It can be overridden by making an alternative LED assignment in userSetup().

Peripherals

• USART0 (Universal Serial Tranceiver 0)
• Timer2: used as a watchdog timer for receiver
