DAVROS stands for "David's AVR Operating System" and is a foray into the world of embedded systems. It is one of my AVR Projects.

The development system I am using is the EasyAVR3 from mikroElectronica. Though not even up on their site yet, I was able to obtain one through their UK distributors: Breadboarding UK

For v1.0, I am targetting the following features:

  • ATMEGA8535 processor.
    • 8MHz, inbuilt clock
  • HD44780-based display (optional).
  • HD61202-based display (optional).
  • SPI-based peripherals:
    • SD card/MMC card for storage, instructions
    • DAC for mono audio out
    • 4-channel ADC for analogue input
  • UART-based peripherals
    • GPRS for communications
    • RS232 Serial for PC communication

For v 1.1

  • Ethernet
  • Composite video out
