Page 7: I²C - Communication
I²C - communication 2 I²C - communication General The digital pressure measuring cell is equipped with a digital I²C interface and optionally an analog out- put. The communication via the I²C interface is described in the following chapters. This includes the correct electrical connection, the entire design as an I²C-bus with master, slave and pull-up resistors. -

2 I²C - communication 2.2.4 Connection to the computer NOTE! The digital pressure measuring cell can be connected with a PC/Notebook via PC-Interface with Con- verter USB/I²C TO39. see chapter 4.3 "Connection to the computer", Page 19 Bit rate The digital pressure measuring cell works over two sets of bitrates (transfer speed). -
Page 10: Addressing
2 I²C - communication • Valid data Data is transmitted in bytes (8 bits) starting with the most significant bit (MSB). Each byte transmitted is followed by an acknowledge bit. Transmitted bits are valid if, after a start condition, SDA remains at a constant level during the high period of SCL. -
Page 11: Write Operation
2 I²C - communication WRITE Operation An I²C WRITE operation is initiated by the master sending the slave an address byte including a data direction bit set to ‘0’ (WRITE). The address byte is followed by a command byte, and for applicable com- mands two additional data bytes (optional). - Page 12 2 I²C - communication...

Page 16: Interpretation Of The Sensor Data
3 Sensor data Interpretation of the sensor data 3.2.1 Pressure The conversion of the digital values to decimal pressure values is realized by a linear function defined by two points (P and P P[u15] P[bar] P[bar] example : 3277 (10 % of 15 bit) : 29491 (90 % of 15 bit) The minimum and maximum pressure values are stated in the order confirmation. -
Page 17: Temperature
3 Sensor data 3.2.2 Temperature The interpretation of the digital temperature values follows a linear function. To interpret the digital values of the temperature it is necessary to read the parameters T and T once from NVM (0x45 and slope offset 0x46), by using the commands (... - Page 18 3 Sensor data...
