Hi Graham :) Yes, I tried. On default I2C-0 and I2C-1. I2C2 was disabled by default and i enabled it when the Beaglebone was running with the "echo BB-I2C1 > /sys/devices/bone_capemgr.9/slots" command. The sensor was connected to the board. And here is another question: if i enable the I2C2 bus real time on the board, should it see the sensor or the memory map, without restarting the board?
