It's a WIP project. Contact me for offering help , questions etc

Goal

Provide a smart , small and cheap board for actuators / sensors / in automation and robotic context . Small units could be easily integrate in robotic_arm , little robot like swarmbot , sensors projects like CARACA ... more on robotic

Features

• Smart , using CAN network and industrial quality software , to create a distributed network. see CANopen for software.
• cheap and small :
  • no electronic parts to program/debug as Arduino mini pro , Lilypad Arduino ... use a CAN bootloader ( or a programmer )
  • no switch to set Node-ID , use LSS fastscan ( or set it with the programmer )
  • no battery ?

Proposal design

Use an AtMega from automotive serie as the ATmega64C1 with a CAN transceiver or just a DIP connector to let user choose his transceiver.

Possible programmer

JTAG

look http://objects.reprap.org/wiki/CAN_AVR#JTAG

Serial with a bootloader

• UartSB from seeedstudio
• FTDI Basic Breakout from sparkfun

relative commercial products

• http://www.candip.com/candip-m162.htm ATMega162 + CAN controller SJA1000
• http://www.grifo.com/CAN/uk_gm1.htm Atmel T89C51CC01

MCU considerations

Atmel AVR ( see CAN_AVR ) or others products if AVR are not suitable for our constraints. Good alternative could be AT89x microcontrollers based on the 8051 architecture, industrial standard.

OS considerations

Perharps we need realtime thread support so FreeRTOS could be a good option. useful topics :
