The wiki page now contains instructions on how to connect the naviboard v3 to a graphics card [1]. This should enable everyone to use it and requires only three parts: a VGA connector (or DVI or HDMI), a 3V regulator (LDO) and a naviboard. Connect everything as described, plug it in, load the i2c-dev module and run i2cdetect to check if it's working. If the instructions are not detailed enough, please complain and I will try to clarify any issues. I tested this setup with the integrated Intel graphics card on my notebook and it worked fine, a test with an nvidia card will follow. To find the right I2C bus on your machine, load the i2c-dev module and run i2cdetect on all available busses (look in /sys/bus/i2c/devices for i2c-*, or simply try this: for i in `seq 1 20`; do echo $i; i2cdetect -y $i; done;). The commands output should be different if your monitor is disconnected (or switched off). Have fun!

I don't have experiences with USB-I2C interfaces but anyone should work. Be sure to add a 3V voltage regulator (LDO) if you want to power the board from USB which supplies 5V. If you want you can build your own adapter using an old VGA cable. The I2C bus is used for DDC. If you have a spare VGA or DVI connector on your computer you could use it to connect the FRNB (http://en.wikipedia.org/wiki/VGA_connector pin 12 and pin 15). To power the board you could try pin 9 which should carry 5V. Use a LDO regulator to get 3.3V or 3.0V which is needed for the sensors. The I2C bus needs level translation too. Fortunately, if you have a complete board, the needed chip is already included. I will add a section to the wiki about how to connect the board to a 5V I2C bus. Pinout and more documentation will be added too. Hope that helps, Christoph ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
