Hello, I am working on a BBB project. I am looking to connect 3 devices to the I2C bus. I already have the DS1307 RTC model working. i2cdetect shows
60: -- -- -- -- -- -- -- -- 68 -- -- -- -- -- -- -- I then connected the MCP23017 to the BBB, but cannot see the the address I set. I tried this with several different boards, that worked perfectly on a RasPi. I am really desperate to get a solution, but have no idea what I could do to fix the problem. This is what I did so far: - disconnect the RTC and kept another I2C device connected => 68 disappeared - changed the power supply from USB to external - used all the different power ports P9_03-P9_08 - used the second I2C bus What else can I check. Is my BBB buggy? I am running: Debian GNU/Linux 7 (wheezy) uname -a shows Linux arm 3.8.13-bone28 #1 SMP Thu Sep 12 23:22:35 UTC 2013 armv7l GNU/Linux Content of /etc/modules snd-bcm2835 i2c-dev i2c-bcm2708 No uncommented modules in /etc/modprobe.d/fbdev-blacklist.conf Why is the RTC module working and all the other modules aren't. Any advice would be really appreciated. Thank you in advance. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
