I2C addresses can be notified with 7 or 8 bits. The Tracii software provides the option use I2C-bus device addresses in 7 and 8 bit notation.
I.e. the least significant bit of the first I2C-bus message - the read or write bit - is no part of the address.
In Tracii Talk the R/W bit will be set automatically due the r or w after the address. In the 8 bit notation the LSB in the address byte is ignored.
So a device located at I2C-bus address 50h is addressed by the value 50w/r in the 7 bit notation or A0r/w in the 8 bit notation.
