Issue with address range - I know about it, but there are some more questions about 7-bit and 8-bit addresses - so for scanning more is better.
My question is now mainly about setting
SCL_PIN 6
SCL_PORT PORTD
SDA_PIN 7
SDA_PORT PORTD
I I get it right, it should be the port into which IO expander is connected. According the schematics http://arduino.cc/en/uploads/Main/Arduino-Pro-Mini-schematic.pdf, D6 and D7 are connected to PORTD, pins 6,7. Is that right ?
If this is right, last question could be about HW part of thing. Accelerometer is using 3.3V logic, so it's high is around 3.3V, what could be low for 5V logic ?
