Hi, trying to read out the data from some pressure sensors. They are used as slaves an my arduino as master. My question is: How do i figure out the adresse of the sensors?
The datasheet says that the sensors have some preconfigured slave addresses.... Here the part from the datasheet:
Slave address: The I²C-bus master-slave concept requires a unique address for each device. The HCLA has a preconfigured slave address (1111000xb). By factory programming it is possible to define a secondary slave address additional to the general one. According to I²C specification 127 different addresses are available. The sensor will then listen to both slave addresses. After generating a START condition the master sends the address byte containing a 7 bit address followed by a data direction bit (R/W). A "0" indicates a transmission from master to slave (WRITE), a "1" indicates a data request (READ).
Do I need to read the address from (1111000xb) before I start the measurement? Or is the a nicer easier way faster way to handle that problem? Thanks a lot kohlmeise
