C Communication
Communication to the Model BPS120 is read only. To read the pressure counts, the master performs a read request by asserting a start
condition, sending the 7-bit address of the part (0x28), and sets the read/write bit. The master then waits for an acknowledgement. The
acknowledgement is sent by the pressure sensor along with 2 bits of status and bits 13:8 of the pressure counts, the master acknowledges the
first 8 bits, and the pressure sensor sends the remaining 8 bits of data. The master then does not acknowledge and sends a stop condition,
signaling the end of the transaction.
Specifications are subject to change without notice.
Users should verify actual device performance in their specific applications.
