Hi, I found a sensor that works with I2c protocol, but in the list of the command bytes that must be sent, there is somthing strange.
It gives somthing like that:


    command                       byte 0    byte 1    byte 2

read measurment byte 0       0x02      0x41     R+0x03
read measurment byte 1       0x02      0x42     R+0x03
.
.
.


it is the "R+" in front of the third byte that I don't understand, can anyone help me?
L.C.

A link to the sensors data sheet would help ;-)

I guess it means "Reading". The address probably is 0x01, which result then in a writing address byte of 0x02 and a reading address byte of 0x03.
