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 CAN_AVR#JTAG
Serial with a bootloader
FTDI products :
Note FTDI bitbanging is not well supported with avrdude under linux
TODO ftbb :
- ftdi_usb_open: device not foundSegmentation fault
- port to 5.5 ( API has changed since 5.1 )
- find good solution to run it as user
- test arduino configuration
- ISP LED
relative commercial products

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 :
