information about AVR

Possible programmer

Serial with a bootloader

FTDI products :

• UartSB from seeedstudio
• FTDI Basic Breakout from sparkfun

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

JTAG

Warning : standard atmega has no jtag.

• AVR Dragon low cost JTAG/ICSP ( 50 $ ) , see :
  • http://support.atmel.no/knowledgebase/avrstudiohelp/mergedProjects/AVRDragon/AVRDragon.htm
  • http://www.hbrobotics.org/wiki/index.php5/AVR-Dragon_Under_Linux
• AVR JTAG ICE clone , kits start at 15 € , a good choice for DIY guy.
  • http://aquaticus.info/jtag
• low cost parallels jtag ( 5$ ) , slow but cheap ( for occasional needs as bootloader flashing ).

Of course, JTAG interface is not useful for user who don't need bootloader flashing and embedded software developing

AVR ISP

• [1] use ftdi on arduino board to emulate an ISP programmer
• USBtinyISP AVR Programmer Kit
• USBprog - An open source all purpose tool (AVR ISP, ARM7/ARM9, AT89,JTAG, RS232, IO) seems to be a killer product but users reports a lack of quality software and no answer on patch submits
